I have a Ford Mondeo 2.5 V6 SI and I'm a little confused. I've read that it is best to replace the plastic water pump with a metal one, but upon doing a bit of research, just as many people say it is best top have a plastic water pump as the metal ones rust. I'm a little confused, could some one help.

ALSO Why would Ford make a water pump that rusts, surely it would be rust proof or galvanised or something...??

HI Mate

Dont listen to the hype, Metal ones DO NOT RUST.

They are normally made of alloy but even if you get one made of steel it will last the life of the car.

Its a must to change the plastic one as the plastic impeller breaks easily and this happens to almost every V6.

The result of a breakage is loss of water flow, engine over heats and warps the heads so the head gasket fails.

A new head gasket will set you back around £1200 - £1500 at a garage.

So, and I think every one will agree that you should change the plastic ford unti to the metal pump for peace of mind.

Hope this clears things up a bit.

Cheers

You sure? The one I took off my car was slightly rusted (if only I'd known it already had a metal one fitted!)

in theory it should'nt rust in any case, as the chemicals in your coolant should prevent rust from occuring :L
