When i got my car back after the mapping of the ecu a few things weren't right with the car.
The cooling fans are constantly on high speed and yesterday i noticed a few drops of coolant below the thermostat housing.
The car takes a long while to reach temp and the people who mapped the ecu said it took a while to reach temp even after they removed the fuse for the fans.
Now would a thermostat that remained open cause the fans to stay on?
I dont have much experience with working on engines so alot of this is new to me.
How do i test it without removing the thermostat?
