Engine Cooling problem
1997 GMC Jimmy Four Wheel Drive Automatic

Most likely the thermostat has stuck in the open position
(luckily). I know where it is could you tell me the R&R proceedure. Removing the throttle body assembly sort of scares me.

Welcome to the forum, You don't take the throttle-body off according to my info. It does say to take bracket loose from throttle-body, just a couple of nuts, then move the bracket. Take out the bolts for thermostat housing.
