this is a write up about changing Thermostat on the S model, i read other post, i don't see any on the S model with pictures, so i took some pictures while i am doing it. and it's not that difficult like they said in the book, should take less than an hour.
and put the fan back and connect the power back, put reservoir back reconnect the hoses and don't forget to add coolan. start the car and let it warm up and check for leaks. like i said, it should take less than an hour.
