Hi,
I am wondering did GM use the same power steering pump on all Firebirds and Camaros or were there different types used on the 4 cylinder, V6 and V8 models. I have a slight leak in mine and am thinking of replacing it. I tried a bottle of "Power steering Pump stop leak" but that only worked for a few weeks. Is it worth replacing the seal on the existing pump?.

Thanks.

 

Regardless of how the leak gets repaired, the pump has to be removed. Once it's out, removing the sheave is easy with the right puller, and once that's off, the seal is fairly easy (both the shaft and case seals). If you have the equipment, it's worth a shot. Otherwise, reman pumps are fairly inexpensive.

 

It's worth a try; but unfortunately, the usual cause of a leak, is a bent reservoir.

The pump itself is a small cast-iron thing. The reservoir is a big sheet-metal piece that wraps around it. The pump goes into the reservoir from the front. There is a HUGE O-ring on the front, about 4" in diameter, that seals the pump to the reservoir. When people pry on the body of the pump to tension the belt, they invariably warp the reservoir, and that O-ring can't possibly seal any more.

Repairing the pump to fix a leak therefore has a rather low probability of success. You're probably better off just rpleacing it, if you can get one.

 

Thanks guys for the information, I will look for a reman pump first. Were there different pumps used on the different models 4 cylinder, V6 and V8 or were they the same across the range.
