Advice/tips for replacing the water pump on a v8 D2?

[Vyntr]

hi all.

My water pump just failed rather spectacularly, (bearing failed) so i'm off to get a newy. I have done this before in my old D1 but this will be pretty much my first time working on the D2 so any advice or tips or WARNINGS would be hugely appreciated!

I don't have any manuals as the car didn't even have the stock one when i bought it and i haven't got an aftermarket one yet. I'll be looking this arvo but i'm not holding my breath.

the only thing i've been able to find on here that is relevent to the actual replacement proceedure is a post by stevo saying that "they are not to bad to do did mine at 140,000 km's, you have to remove the centrifugal oil filter assembly so you can get the water pump out"

i'm hoping this will be obvious once i figure out how to get the fan assembly off but as i said, any tips would be a real help!

Cheers, Vyntr

thats for the TD5.

theres no super special tricks for the v8s pump other than getting your hands on the 32mm fan spanner to remove the viscus coupling.

once youve got the shroud off drape a towel over the radiator then place a piece of cardboard box over the top of the towel to protect the radiator.

A magnetic retriever is also good to have for dropped bolts.

new gaskets is obvious but you should also replace the thermostat and its gaskets.

if you have access to a tap and die set or a set of thread clearing tools clean up the threads of all the bolt holes prior to assembly.

loctite #3, 567 and 243 will probabley be helpful at various stages as well.


good luck.

Its a 36mm spanner for D2V8 (and Td5); and the V8 is a RH thread.
The advice I'd give is to do it quickly, IE don't leave it off overnight etc, as the next coolant leak you will be dealing with is the timing cover to block face gasket, they are notoriously brittle and will leak after a pump replacement:(

ahhh whooops on the size....

last one I did was an older one.

thanks guys, i'll be grabbing a 36mm spanner from bunnings then :)

timing cover gasket? Does this get dammaged because of the water pump going or did you just mean that usually when one goes the other soon follows?

i think he means that if you leave it overnight, it dries out and then leaks soon after, i know this from experience with my D1 v8, had to do the same thing

Yes, the timing cover gasket does seam to suffer from the unclamping and then clamping of fitting a water pump, as a few of the bolts go through to the block face.

You will need to grind the spanner end thinner to fit between the bolts and the pulley.

righto, good to know!!

an adjustable riggers crescent did the trick nicely, without needing to be ground at all, and it's a little longer than ordinary ones too.

I can fully quantify this as having removed 3 times in two weeks (don't ask!)

Definitely RH thread, If feasible pull t/cover at the same time, replace front main seal (it's cheap insurance)(remember to pack oil pump to prime) and reseal with loctite master gasket/flange sealant, great stuff. W/pump and t/cover bolt are 5/16 unc by memory.
