Your thermostat temperature should be listed in the parts catalog at your dealership and your local auto parts store may also be able to tell you what temperature thermostat your vehicle came stock with. What should my coolant temperature be? It should always be between the temperature your thermostat is designed to open and the temperature your cooling fans are designed to come on at. If temperatures get too hot the coolant can start to boil reducing its ability to cool the engine and possibly causing damage to the engine and its components. If temperatures in your engine stay too cool combustion will have to be too rich to keep things running smoothly. Most engines are designed to run with coolant temperatures between 160 degrees and 200 degrees. If the thermostat is fully open and engine coolant temperature continues to rise the engine cooling fans will turn on to increase air flow through the radiator and reduce coolant temperatures. The thermostat is either a mechanically control valve or electronically controlled by your engine’s computer and opens to allow more coolant to flow through the radiator where it can be cooled. The coolant temperature is controlled by two things, your vehicle’s thermostat and the engine’s cooling fans.
As vehicles and their engine control computers have gotten more advanced, the computer even tracks coolant temperatures and will set an engine code if the temperature gets too high.ĭifferent vehicles are designed to operate at different temperatures to protect the engine and it’s components as well as allow it to operate at maximum efficiency.
#Coolant temperature range driver
Almost every vehicle sold in the US has a temperature gauge installed to make sure the driver has the opportunity to keep an eye on coolant temperatures. Coolant temperature is a very important thing to keep track of in your vehicle.
