Vital part required to circulate coolant around engine. Heat produced by engine combustion is absorbed by coolant which then passes through radiator to cool down before returning to engine. Water pump is situated between radiator and engine and driven by pulley through timing belt or fan belt. Water pump causes coolant to circulate.
Consists of body (aluminum diecast, cast iron, aluminum gravity etc), flange(forged steel, sintered iron etc), impeller (pressed steel, cast iron, synthetic resin etc), water pump bearing and mechanical seal kit.
Its material is decided dependent upon performance level, quality as well as customer requirements and working conditions. Revolution power of crankshaft is transmitted to impeller through water pump bearing. Impeller vanes drive coolant out into circulation jacket.
Vortex chamber of water pump filled with coolant is separated from water pump bearing by mechanical seal kit.
A sliding seal, like mechanical seal kit, must be lubricated all the time it is moving by coolant fluid.
Engulfed (lubricating) coolant evaporates out into water pump bearing side and exits through weep hole on body.

Worked Perfect
GMB® 190-2160 - Engine Coolant Water Pump
Nice quality water pump from GMB. I've used GMB pumps for years, so when I found this pump hear on TRUCKiD.com at this price, I bought it immediately. It even came with replacement bolts with 10mm hex socket heads to replace the strip prone button head torx bolts that are factory on Volvo. Everything went together great with no leaks.

GMB - Water Pump
GMB® - Engine Coolant Water Pump
I bought this replacement part for my 2005 Chevy Aveo. Thanks to TRUCKiD.com's accurate description of this replacement part it was exactly what I received and was a perfect fit. Although this parts installation was a little difficult and time consuming, but the part itself went in with ease. I have quite a bit of experience working on and replacing parts on many vehicles so if you are not extremely confident and not very experienced I would recommend that you find an automotive shop to replace this particular water pump. The reason I recommend you find a shop to perform the work is because it requires removing the timing belt and requires certain tools too remove and replace the timing belt. Since I replaced my old water pump with the GMB water pump my vehicle hasn't had any problem's overheating.
