Engine Cooling System

Everything you need to know

Engine coolant has a primary function of convective heat transfer for internal combustion engines. The correct coolant mixture and quality will prevent freezing in winter, prevent boiling in summer, prevent rust and corrosion of metal parts, become a good conductor of heat, and aid in preventing electrolysis.

A cooling system works by circulating liquid coolant through passages in the engine block and cylinder head(s). As the coolant flows through these passages, heat is transferred from the engine components to the coolant. The heated coolant then makes its way through a rubber hose to the radiator in the front of the engine compartment. As it flows through the thin tubes in the radiator, the hot liquid is cooled by the air flow entering the engine compartment through the grill in front of the vehicle. Once the fluid is cooled, it returns to the engine to absorb more heat. The water pump has the job of keeping the fluid circulating through the system when the engine is running.

How it works

Water is an excellent fluid for cooling as long as it remains in a liquid state, but when water turns into steam it has virtually no capacity for heat transfer. Timing waterless coolant is a superior fluid for transferring heat in engines because it remains in a liquid state and able to withstand boiling point up to 190 °C — well above the operating temperature of an engine.

Within an engine cooling system, the hottest surfaces are those adjacent to the combustion chamber, specifically the cylinder liners and cylinder head. These hot spots cause water to vaporize, preventing efficient cooling and causing loss of performance and unnecessary engine damages. When the coolant fails in this situation, eventually the engine will becomes even hotter, causing more hot spots and more steam.

Timing waterless coolants will not boil around these engine hotspots, maintaining efficient cooling performance even when the engine is put under extreme conditions. When water turns to steam it pressurizes the cooling system, putting stress on hoses and other components. The significantly higher boiling point of Timing coolants means significantly less pressure than water, resulting in a less stressed cooling system.

The Benefit Of Having a Clean And Healthy Engine

Extended Working Life

A clean engine might actually last longer than a dirtier version of the same engine. Built up residue can make it more difficult for your engine to get its job done, causing it to work harder than it should. The extra demands can cause the engine to wear out sooner than it normally would, and it might lack in efficiency during that time period. Your specialist might also uncover hidden problems when performing an engine steam cleaning that would have slipped through the cracks and continued to worsen.

Improved Vehicle Safety

Safety is one of the first factors that many potential car buyers consider when surveying their options, especially when it comes to parents buying vehicles for their families. The residue and fluid stains that build up on your engine and undercarriage can contribute to fires. Thanks to engine cleaning, you can have all of this harmful material scrubbed away and enjoy a safer vehicle for yourself and your family.

Increased Resale Value

Engine cleaning is done for both practical and aesthetic purposes. Aesthetically, engine steam cleaning will leave you with a shiny engine that looks substantially better from a cosmetic standpoint. Better aesthetics have a tendency of encouraging consumers to buy products for a higher price, and the situation is no different when it comes to used cars. If you want to get as much as you can for your used vehicle, consider engine steam cleaning to bring your old and discolored engine back to life.

5 Benefits Of Changing Coolant Liquid

Removes Rust and Scale Deposit

Over time rust and scale deposits build up within the radiator. A flush helps to remove these deposits which get pushed out with the old anti-freeze. This is important since these build ups can cause overheating or even damage your radiator.

Lubricate the Water Pump

The additives in the coolant lubricate the vehicles water pump. This will lengthen the life of the water pump.

Removes Contaminants

Flush completely drains the system of the old anti-freeze which means that any contaminants that have made their way into the system will be flushed out as well. The additives in the coolant can lose important anti-corrosive properties over time which leads to the build-up of particles. A radiator flush will remove these particles from the system.

Inspection of System

Most places will perform a complete inspection of your cooling system when they do a radiator flush. They will use pressure tests to check for leaks in the system. This should be included in the price of the flush and if it isn’t it might be best to go somewhere else.

Protect against Rust and Foam

The new anti-freeze will have additives that help prevent rust and build up. It will also prevent foaming in the system which helps it operate efficiently.

How Car Cooling System Affected Engine

Just like human beings, the car needs to dissipate heat in order to avoid overheating and exhaustion. During combustion, the engine produces large amount of heat – about 4,000 degrees Fahrenheit. This is too much for the engine to bear so a cooling system is needed to keep it at a normal temperature. Cars usually overheat due to a damaged part in the cooling system, especially the radiator, the heart of the cooling system. It is therefore necessary that all its auto parts must be in proper working condition to ensure that the whole system works efficiently.

Aside from the radiator, the cooling system is composed water pump, freeze plugs, head gasket, thermostat, hoses, heater core, fan clutch and radiator fan. All these auto parts have special roles to perform thus the absence of one could significantly affect the whole cooling process and of course, the engine’s performance. Take for example the hose, this may seem to be just an ordinary part but once broken, the coolant can escape and so it’s no longer possible for the system to cool the engine. Even just the cap of the radiator is important. It holds the pressure in the cooing system; thereby, affects its stability.

How does the cooling system of your car work? The coolant, which is a mixture of anti-freeze and water, is the one that absorbs the heat from the engine. It is drawn by the water pump from the radiator and is pumped through engine block and the cylinder head to absorb the heat from the engine and its parts. It goes back to the receiving tank of the radiator through the radiator hose. The radiator has tubes that contain large amount of water and has fin area to allow outside air to pass through. As the coolant spreads over the top of the radiator tubes, it transfers heat to the air.

The performance of your car is greatly dependent on your cooling system. No matter how gutsy its engine is, it can’t work normally without a cooling system. The engine can even be inutile in an instant if it overheats and all other auto parts under the hood can also be damaged. They could melt as the engine burns the fuel inside the combustion chamber and the pistons in the cylinder could expand extremely that they can no longer move to complete the whole process in the engine.

Your car can possibly overheat as well. Engine overheating is one of the most common problems auto users encounter. You can avoid this by adding water to your radiator. So if you notice a problem on a particular part in your cooling system, consult the best auto mechanic in town. But if you think the problem is worst, you may as well replace it right away.

Using VR-12 in your vehicle’s maintenance will provide the ultimate cooling system protection, allowing you to reduces cylinder head temperatures, prevents corrosion, rust, oxidation and electrolysis, more fuel-efficiency, more $avings and go green.

The engine is a controlled explosion system, that needs to run in a specific temperature range, to operate correctly. This is very important for todays electronically controlled emission engines in order to maintain peak performance, maintain fuel mileage and emission standards. VR-12 keeps the cooling system working at its higher point of performance, which allows the vehicle’s engine to work as it was designed.

Car Care : The Key to a Long-Lasting Vehicle

1. Check all fluids

Check all fluids, including engine oil, power steering, brake and transmission as well as windshield washer solvent and antifreeze/coolant.

2. Check the hoses and belts

Check the hoses and belts to make sure they are not cracked, brittle, frayed, loose or showing signs of excessive wear.

3. Check the battery

Check the battery and replace if necessary. Make sure the connection is clean, tight and corrosion-free.

4. Check the brake system

Check the brake system manually and have the brake linings, rotors and drums inspected at each oil change.

5. Inspect the exhaust system

Inspect the exhaust system for leaks, damage and broken supports or hangers if there is an unusual noise. Exhaust leaks can be dangerous and must be corrected without delay.

6. Schedule a tune-up

Schedule a tune-up to help the engine deliver the best balance of power and fuel economy and produce the lowest level of emissions.

7. Check the heating, ventilating and air conditioning (HVAC) system

Check the heating, ventilating and air conditioning (HVAC) system as proper heating and cooling performance is critical for interior comfort and for safety reasons such as defrosting.

8. Inspect the steering and suspension system

Inspect the steering and suspension system manually including shock absorbers, struts and chassis parts such as ball joints, tie rod ends and other related components.

9. Check the tires

Check the tires, including tire pressure and tread. Uneven wear indicates a need for wheel alignment. Tires should also be checked for bulges and bald spots.

10. Check the wipers and lighting

Check the wipers and lighting so that you can see and be seen. Check that all interior and exterior lighting is working properly and replace worn wiper blades so you can see clearly when driving during precipitation.

How To Reduce Your Vehicle Maintenance Costs

If you want to avoid nasty and unexpected surprise maintenance costs, sticking to a well-organized schedule of preventative maintenance is something you are going to want to get used to. The reason is simple – frequent maintenance will keep your car in good health, ensuring you get the most out of all those expensive-to-replace parts. While it might sound counter intuitive, the solution to reduce maintenance costs is to stick to a prescribed maintenance schedule.

Keeping your vehicle’s fluids new and clean is priority number one when it comes to minimizing future costs. Frequent oil changes can prevent the build-up of harmful deposits that rob your car of fuel economy and power, as well as make internal components work harder. A harder working engine is one with a shorter life span.

Even if your vehicle is brand new, it is a good idea to check the oil every few hundred mile. If the level slowly gets lower between oil changes, you might have an issue with your engine. The same applies for your vehicle’s brake fluid, manual clutch fluid or your automatic transmission fluid.

While keeping an eye on your vehicle’s fluid levels is a good first step toward improving your investment’s longevity, sticking to the recommended service intervals in your owner’s manual is equally important.

A good example of this is a timing belt replacement. Timing belts and chains keep the different parts of a car’s engine in sync with each other and on average should be replaced every 60,000 miles. Because of the infrequency of a timing belt change, it can be easy to overlook this vital service. However, waiting another 5 to10k miles is not advised, as the results could result in a catastrophic engine head failure, a repair that could cost you over double the amount of a timing belt service.

Nevertheless, there are a few ways to trim money from your regular maintenance schedule. By and large, private, independent shops charge less than licensed dealers because they have access to less expensive aftermarket parts as opposed to typically pricier Original Equipment Manufacturer (OEM) parts. If your vehicle is out of warranty there’s little reason to use the dealer over a local shop, and if the local guys are charging less money, then, by all means, use them.

Don’t forget to save all your service receipts. Not only are they good to have for reminders, but having them available for potential buyers will also increase the residual value of your car.

50 Named Top Safety Pick

New standards for headlights and front-end crashes are making it harder for new cars and trucks to receive an insurance-industry-backed group’s highest safety rating. The Insurance Institute for Highway Safety (IIHS) gave just 15 vehicles its highest rating of Top Safety Pick+ for 2018, compared with 38 for 2017 and 48 for 2016.

For the top rating, many vehicles were tripped up by the addition of a passenger-side small-overlap front crash test that was added to the criteria for the award. The IIHS has been rating vehicles for driver’s-side protection in small-overlap front crashes since 2012 but only recently developed the test for the passenger side. It released the first test resultsin October. Vehicles had to get an Acceptable or Good (top) rating in the test to be named a Top Safety Pick+.

While automakers have been beefing up the structural integrity of the driver’s side of their vehicles, some may have neglected the passenger side, IIHS said. IIHS senior research engineer Becky Mueller told Car and Driver that automakers have been adding cross bracing and stronger metal to improve areas around the vehicle’s door frame and floorpan. “Vehicles that applied the same structures to the driver and passenger sides of vehicles typically performed well for both the driver and passenger small-overlap tests,” Mueller said. “This means that manufacturers already have the know-how to better protect passengers in small overlap.”

But apparently, not all cars and trucks have been improved across their entire front ends. In a press release, IIHS president Adrian Lund noted that drivers “expect that their passengers, who are often family, will be protected just as well as they are. Manufacturers have been taking this issue seriously since we first shed light on it, and we’re confident that good small-overlap protection will become the norm on the passenger side, just as it has on the driver side.”

Nearly 50 Named Top Safety Pick

In addition to the 15 Top Safety Pick+ winners, 47 were named Top Safety Pick. There was no passenger-side small-overlap requirement to get the Top Safety Pick award.

IIHS said the vast majority of the winners were optionally equipped, because front-end crash-prevention technology and decent-performing headlights—two key factors for the Top Safety Pick honor—are generally not available on base-trim cars and trucks. It noted that some automakers are vowing to make automated emergency braking standard by 2022 and singled out Toyota as being ahead of that curve. Seven of its models have it as standard: the CamryCorollaPriusPrius Prime, and Highlander and the Lexus IS and NX. Nissan has pledged to make it standard on most 2018 models.

Meanwhile, automakers continue to have some trouble with the IIHS’s headlight tests, which are relatively new. IIHS evaluates headlights on how well they illuminate the road as well as the amount of glare they create for oncoming vehicles. For a vehicle to be named a Top Safety Pick, its headlights need to be deemed Acceptable or Good, and they have to reach the top rating of Good for a vehicle to be labeled Top Safety Pick+.

Among the 15 models given the highest award of Top Safety Pick+, Hyundai Motor Company led all automakers, with its Hyundai, Kia, and Genesis brands placing six models in the top category. It was followed by Subaru, which had four models, and Mercedes-Benz, with two. Toyota, BMW, and Ford each placed one model on the Top Safety Pick+ list.

Checking Your Coolant and Cooling Fan

How to check your coolant

  • It’s essential to correctly identify the expansion tank – check the vehicle handbook for the location of the coolant filler cap, and follow any vehicle-specific advice given (adding antifreeze to the screen wash, brake fluid or power steering reservoir would be a very bad idea.)
  • The coolant should be between the min/max marks on the side of the expansion tank
  • Check any hoses that you can see at the same time; wet or white staining is a sign of possible problems to come
  • If the coolant needs topping up, don’t remove the filler cap unless the engine is cold – you could be scalded by a sudden release of pressurised hot water
  • Make sure you use the right sort of antifreeze – the different types don’t mix well
  • Antifreeze doesn’t just protect your engine in winter. It helps stop corrosion and scale build-up all year round
  • It’s not normal for the coolant level to drop; if you see that it has, get a garage to take a look

Engine coolant

How to check your cooling fan

When your car’s moving, air flows through the radiator to keep your engine’s temperature ‘normal’, but if you stop – in a summer traffic jam for example – your engine has to rely on a thermostatically controlled electric cooling fan to force air through the radiator.

It’s important to check regularly that the fan and temperature sensor are working. Here’s how:

  • Set the car heater to cold
  • Run the car until the engine reaches normal temperature
  • Allow the engine to idle for around five minutes
  • Watch your temperature gauge – don’t allow the car to overheat

Cooling fans should cut in automatically. If they don’t there may be a fault with the fan temperature sensor, the wiring or the fan itself.
