02 tl type-s.
Started this week, car temp sensor gauge goes up near hot while in park. When I drive the car its on normal reading even while driving long distances. As soon as put the car in park and wait about 5 minutes temp gauge goes up. When I turn the car off both fans kick in to cool off engine for a couple of minutes. I check the cool level and thats good, there are no coolant leaks. Replaced ECT sensor. Any Ideas???
Thanks

 

try a new thermostat, proably stuck partially closed, try increasing the revs at idle to get the coolant flowing and see if it starts to overheat then

also might be a plugged radiater; internaly (coolant passages) and/or externally (the fins) IDK

also is the coolant a 50/50 mix of coolant and water; coolant protects from corrosion, drops the freezing point, raises the boiling point, etc. ,etc. while the water is what actually does the work of keeping the engine cool by carrying away the heat from the block to the radiater

 

ok thanks i will look into this during the week.
