Check Engine Light is on. Advanced Auto Parts checked codes. Shows thermostat stuck open. Engine and oil radiator fans run 100% when engine is running. Fans don't run with ignition in "on" position but engine not running. Could thermostat be the problem? Also, how hard is it to replace by somewhat experienced do-it-yourselfer? I have new thermostat, but don't want to waste antifreeze.
