Hey folks, your friendly giant here.

Fitting a water pump tommorow on 1992 998cc. Part has arrived with gasket which is fine, just wanted to know if theres any pre-fitting proceedures I should do like greasing up or WD40 in the moving part.

Many thanks

[Retro_10s]

nah, coolant acts as a water pump lube anyway, just check it has free smooth movement. WD40 will just get washed away anyway.

i would put a very light smear of multipurpose grease around the gasket though, just helps it seal it up properly.

cheers mate in regards to tightening bolts up I dont have a torque wrench to hand so literally as tight as possible without sheering?

[Retro_10s]

No i think there has to be specific torque setting otheriwse the thread on the bolt may stretch etc......, could end up damaging the block..... hmmmmm, let me see........ (be right back...)

Right they have to be torqued to 17lb/ft

damn it no torque wrench

[Jimmyarm]

Buy one, they are important

You can get one from Argos for £15 but I dont think it goes as low as 17 lb/ft.

No one in your club got one that you can borrow for two minutes to nip the bolts up ?

When doing bits like this it is really important to use it to get the seal correct, too tight and you squish the gasket too much and it wont seal properly, too loose and it wont seal properly and will work its way loose.

belive that machine mart has one of the best in its price range.

Like £15 won in a test with a load of others in a mini mag a little while back.

Anyone

[Big_Adam]

A torque wrench is a spring item, as you wind to the correct setting (writen on the body of the tool) a sping hold a sort of clutch. When the twisting force overcomes the spring (IE when the nut is torqued up) the wrench will click or go. Digital ones vibrate or bleep.

that tool zone one is similar to my own one...........which I fuggin hate. I can't set the thing as it's weird. I winds in 12's so it messes with my mind.

So what would be the best one to get as an all rounder. as i guess i better tighten the nuts on my water pump proper.
Could someone give us a link on the best one.. thanks alot

Heard a few people who had no complaints about the halfords own brand jobbie. Think their like £20 odd and good enought for the job.
