Water pump replacement

[Ollyboy]

Hi!

I have bought a new water pump to replace the old noisy one which is on its last legs. After looking at the manual it looks like a reasonably straight forward job and I am going to do it myself.The water pump has a rubber "O" seal and two paper gasgets; the instructions in the 'pump box mention using a sealant

- what sealant is best for the job?

I assumed blue hylomar, but I have no previous experience of fitting a water pump.

Any other advice regard water pump replacement wwould be greatfully recieved.

Many thanks

Oliver

If you're talking about a 1900 late DG engine ? .... I replaced ours (because a stud snapped off in it during replacing the steel water pipe) earlier in the year. There's a large 'O' ring between the face of the pump and the engine,a smaller 'O' ring between the outlet and the steel waterpipe and a gasket where the inlet comes from behind the crank pulley. I used Blue Hylomar to seal the gasket and to hold the 'O' rings in place during fitment, not everyone recommends 'gasket goo' but it does have it's uses.

While it's off I'd check the steel pipe too ... they ain't cheap,but neither's a replacement engine. Also remember to lubricate the fasteners when you re-assemble ... we don't want them shearing off now do we ?

Cheers,Ian.

It's a 1985 "DG" which has an earlier type water pump, but is very similar to the description you gave.

Blue hylomar it is then!

Thanks, I will be inspecting the steel pipe very carefully. The radiator fluid is very clean so I'm hoping there is very little corrosion.......


Cheers!
