I am driving this 91 740 Non turbo, Automatic Tranny, and noticed that it start to leak coolant around the water pump.

can you recommend a good Water Pump brand? I saw there are GMB, GRAF on the markets. Prices are pretty much the same,around $50.00 or $60.00, also I quaoted one brand from AutoZone which only cost 34.99, but don't know the brand yet...

anyway any suggestions for the brand? also I want to ask that high pitch noise the noise from my water pump? cause I've heard this kind of noise for about 2 or 3 months, and not very frequently, but at least you will hear once every time you drive it, especially when I accelerate the car. Last week I found there are some coolant on the water pump right after the hose to the radiator.
and there are some left on the ground too. the leakage is not that bad but just about time to get it fixed.

Just wonder is that noise related to what's going on with the water pump and the coolant leakage?

thanks

The Hepu pumps are very good quality.

My Autozone pump goes about 100,000, save your receipt and you're good for another 100,000 provided you
service the cooling system on a regular basis and don't overtighten the belt.

Good point. I kept 2 cars in brakes for over 4 years using Autozone's Lifetime warranty. Take back the worn, trade for new.

I bought mine at the Volvo dealership for $65.00. I don't know what brand it is but figured it should be on the quality side.

Replace it immediately!! Before it seizes, or worst spins off and takes out your radiator and other things in the vicinity..

Agreed! Heed the warning of the squeeling water pump. When it makes that noise it is ready to sieze. Save yourself a tow truck bill and replace it immediately.
