Pontiac Repair: 1998 pontiac transport, upper intake manifold, pontiac transport

Question
How do you get to the thermostat?

Answer
Hey Burt:


It sucks! plain and simple. you have to take the throttle body off the upper intake manifold and also take that pipe off that runs from the front timing cover along the left valve cover and under the throttle body. then you need a 13MM combination wrench and take the 2 bolts out that hold the thermostat housing onto the lower intake manifold. The top front bolt take all the way out the rear lower bolt just loosen it up enough to wiggle out the housing. Good luck :)
