If it is the 4cly you need to remove your intake, unbolt the thermostat housing from the side of the block (it will be the one with the radiator hose going to it) pull the thermostat out. When replacing with a new thermostat MAKE SURE YOU INSTALL IT WITH THE JIGGLE PIN FACING UP!!!! I repeat JIGGLE PIN FACING UP. Burp the radiator system well and your done. Good Luck

It's a much better idea to replace it. You can try the radiator flush, but no guarantee.
