    Default Waterpump replacement.

    My truck almost overheated. Looked under truck saw leak coming off the harmonic balancer. Removed the fan and belt from the motor and felt under the Waterpump and it is leaking. Ive already removed the vacuum pump and tomorrow morning I will continue to remove the bracket for the power steering. Will the power steering pump have to be fully removed to remove the bracket or can the bracket be moved with the pump still attached? Also will I have to remove the pulley from the Power steering pump to remove the pump?

    Keep in mind, the water pump is attached to the backing plate that covers the timing gears for the IP. So, everything attached to that plate will need to be removed. Only then will you be able to remove the plate with the water pump attached. It is bolted on from the rear, so there is no way around this. No, you don't need to remove the pully from the PS pump to un bolt it and you can just push it to the side.

    Finally got time to really work on my truck. New water pump on. I figure I might as well change the heater hose connector at the crossover housing since it was leaking and the damn thing broke off. Will I need to purchase a new crossover or is there a special technique I can apply to remove the left over part?

    That happened to my suburban, had to drill the remains out. Drill size small enough not to remove the treads, then use a 1/2 inch tapered water pipe tap to remove the threaded remains of the fitting.

    Confirm with Grancito, previous owner did that to mine. Water pipe nipple even made the switch to the new crossover I installed.

    Yes, good conversion, brass water pipe nipple, cut the alloy pipe and put a piece of hose.

    I found a tool kit from Lisle the removes broken heater hose coupler on GM 3.8L, 5.0L, 5.7L, and 6.5L engines. It has two types of extractors one that you hammer in that has splines on it then you reverse it out with a 5/8 socket. The other extractor is a reverse drill type that is used if the part is extremely corroded. It also comes with a rethread tool too.
