Thus, we definitely want to run a thermostat to allow the engine to warm up as quickly as possible until it reaches our desired and designed operating temperature. Most engine wear occurs when the engine is cold, once it's warmed up there is very little wear in a healthy engine.
As we discussed in a previous article, the engine is designed to operate at it's operating temperature. The thermostat is there primarily to help the engine warm up in the morning. Therefore you don't want the flow to be too high as the cooling system's ability to cool the engine will be reduced, not increased. If it spends a lot of time there, it loses far more heat. If the coolant spends a small amount of time in the radiator, it loses less heat. In liquid cooling systems, the ability to cool is determined by a number of factors, but the basic keys are the surface area of the radiator (how big/how many small fins), the air flow through the radiator (fans on/off, speed of car), and how quickly or slowly the cooling fluid goes through the radiator. The thermostat basically behaves like the hot and cold knobs in your shower, if the water is too hot, it turns the cold on a little more and if the water is to cold, it turns up the hot water.By regulating the flow through the cooling system it speeds up and slows down the flow of coolant into and out of the engine block. It sets a floor, not a ceiling on engine temperatures. The thermostat can only determine when the cooling system is allowed to start cooling the engine. Under high loads, they will run at or above the thermostat's fully open temperature - in other words, under hard driving, the thermostat's opening temperature is completely irrelevant. Most engines run slightly above the thermostat's minimum opening temperature under normal loads. The cooling system and load on the engine determines how hot the engine gets, the thermostat fully open will still be the mercy of the coolant system's ability to remove heat. The biggest misunderstanding about thermostats is that people believe they make the engine run cooler. The Function of the Thermostat & Cooling System Basics There are other descriptions that also seem to indicate that they lower engine/intake temps to make more power. Reading these make you believe that a low temp thermostat are a good idea for those "pushing their car harder" and that they somehow improve cooling performance. Stock thermostats are intended for normal driving conditions and aren't made for those intending to give their car a work-out ( false). The MUGEN Low Temp Thermostat NSX S2000 will increase the vehicle cooling ability ( still false) by allowing the circulation of the chilled water earlier than the OEM unit would allow it to ( that part, true).

By lowering the opening temperature to 68 degrees, and full open at 82 degrees there is a smooth transition in cooling ( ?), and you engine will be cooled optimally faster ( ?). The FEEL'S Low Temperature Thermostat Civic FD2 will provide better, more reliable and faster cooling for your FD2 ( false). This will lead to a motor than can now run much more efficiently ( false). The Sard unit will lower the temperature at which the cool water can mix with the warmer temperatures inside the engine ( true). The SARD Low Temperature Thermostat - SST12 Mazda is a drop-in direct replacement for your OEM unit. For best results, it is recommended that the Thermostat be used in conjunction with a low temperature Thermo Switch.

This in turn will give your Honda a chance to be free of overheating ( false). The SPOON Low Temp Thermostat S2000 Integra Civic will increase the vehicles cooling ability ( false) by changing the operation temperature from 90C (stock) to as low as 80C. Here are a few descriptions from websites/manufacturers selling these, notice the trend of extremely vague language: A few months back, we talked about high pressure radiator caps and what advantage they offered, this time though we're looking at a part that is far more perplexing. This week we're talking about low temperature thermostats, another item that nearly every tuning house sells and yet fail to really explain what they're for.
