Everytime i start and the engine and drive the car until the engine is hot, then two or the three blocks later the engine starts overheating and tells me to stop the vehicle. I checked the radiator and it was cold. So what could be the problem the thermostat, or the water sensor etc.?How do i change the thermostat on my 2005 Jetta gli 1.8T thermostat and where is the location of the part?
Before getting into parts changing and a guessing game stop by a RADIATOR SHOP and ask them what is wrong.How do i change the thermostat on my 2005 Jetta gli 1.8T thermostat and where is the location of the part?
if your thermostat stuck close then the computer will trigger a code and the MIL (check engine light) will be on...most likely your water pump is broken, an easy way to check is open the cap of the coolant reservoir, have someone rev the engine between 3k and 4k, see if the coolant circulate in the reservoir (the coolant should come out from the smaller coolant line, from upper reservoir), the coolant should comes out fluently and not dripping !!!...good luck
the thermostat is located behind the alternator inside a black plastic housing with a hose attached to it. when you take it out, stick your finger inside the hole and feel the water pump impeller with your finger, make sure it isn't broken and that it is tight on the shaft. the factory water pumps have plastic impellers that break and fail to circulate coolant.
