My crossover manifold is leaking coolant. I figure while I'm removing parts to get to it I may as well do some preventive maintenance. The STS has about 120K miles. Should I replace the water-pump and/or the belt and tensioner on the pump before they seize I will probably clean the throttle body. Any advice from someone that has been there?
Any sneaky parts that I will need and can preorder?
The creator of the Northstar is a sadist. The bolts for the crossover are a bi**h to remove. I am replacing all 4 'reusable' gaskets to fix my leaks. I am also replacing the throttle body gasket after I had to remove it, the scratchy water pump tensioner pulley and the belt, and the thermostat O ring because of some oozing coolant. There's also a rubber boot on a vacuum line behind the throttle body base that crumbled when I went to disconnect it. Probably a dealer item.. So far I have about $100 into fixing my cooling system. It never gets hot, I just get a small puddle on the garage floor and have to top of the reserve tank.
