How Does  Car Thermostat W ork Car thermostat function: The automotive Car Thermostat is a temperature controlled on and off valve. Any liquid-cooled car engine has a small device called the thermostat.Car thermostat sits between the engine and the radiator.When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator.  This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced drive ability, and engine protection.You can say the thermostat reduces engine wear, deposits and emissions. See  the image shows how thermostat functions when engine is cold and when engine is hot Car Thermostat controls the engine cooling system.The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the...

Coolant What Is The Role Of Engine Coolant In Your Car. Why Coolant Is Used What Is Coolant. There are many types of engine coolant, colors range from the old standard green to the blue coolant in the newew Mercedes and BMW cars. All engine coolants help guard against corrosion and  overheating  if maintained properly. Some of the main differences between the green coolant and the newer mixes is the chemicals made to create the coolant. The new red, blue and yellow coolants are more environmentally friendly and designed to last longer between services. All engine coolants are highly toxic and should be kept away from animals or dumped down the drain. You should not mix the different coolant types, if your engine came with red coolant then you should add red coolant only. The manufacturers of Dexcool (red) have had a problem with the coolant lasting as long as it should, depending on the climate and driving conditions the coolant can decompose causing coolant passage bl...

Car Engine Overheat Troubleshooting Car Engine Overheating Issues Helpful Information Make sure to service your engine coolant per your manufacturers recommendation. Step by step guide on how to troubleshoot and repair an automotive engine overheating or running hot problems, this information pertains to most cars. Difficulty Scale: 4 of 10 Begin with the vehicle on level ground, engine cold (off) in park with the emergency brake set. Step 1  - Engine coolant is used to transfer heat from the engine to the radiator, over time this coolant can dissipate and lose effectiveness. To check this fluid wait until the engine is cold, slowly remove the radiator cap, a small amount of pressure maybe released which is normal, add coolant to just above the minimum level marker. Low levels of coolant can lead to problems related to engine overheating. Always maintain proper levels of coolant in the overflow coolant reservoir tank also, re install the cap properly.  Ad...

How To Inspect Coolant Leak Engine Coolant Leak Fix Helpful Information Many points in a cooling system are able to develop leaks. Understanding the main physical components of the system helps. A leak in the heater core most often results in coolant on the front passenger-side floor. Most automobile antifreezes are either green, red, blue or yellow which are very toxic. Care must be taken when disposing of old coolant, the sweet odor can attract children and pets. When removing the old hoses be careful to not apply excess force to fragile components such as the radiator and heater core. Often cutting old coolant hoses vertically along the connection helps in the removal process. Best Practices To avoid cooling system problems change engine coolant on a regular basis (30k to 40k) to avoid a chemical decomposition which will create an acid that attaches cooling system components and gaskets.

How To Drain Coolant How To Refill Coolant Vehicle Coolant Bleed / Drain Procedure. Helpful Information Coolant can become corrosive if left inside the system for extended periods of time without changing. To prevent this corrosion the coolant must be changed at regular intervals. In cold weather coolant or antifreeze (same thing) prevent the engine block and other components from freezing. Coolant and antifreeze refer to the same product, in below freezing, coolant lowers the freeze point hence the name anti-freeze and in warm weather coolant helps raise the boiling point, "coolant". All engine coolants are highly toxic and should be kept away from animals. There are many types of engine coolant, colors range from green, blue, red and yellow which possess various properties that help against corrosion and overheating. Be leery of harsh chemical flushes because they can cause premature cooling systems failure. Some manufacturers recommend partially filling the sy...
