Getting ready to do my timing belt.
Only one question remains.
When installing the new water pump, do I need to use any sealant on the gasket ?

Ta...

 

They make a tacking sealant to tack the gasket to the pump itself. I used it and I bought it at Advanced Auto parts however any store would have it. Its a white substance and it says its immune to several things coolant being one of them. Worked for me no leaks thank goodness 1,000 miles into the job.

I didnt really know what I was doing however so dont take my advice with my luck I was supposed to use some special Volvo stuff!!

If I recall it was made by Permatex.

I dont think youre trying to seal it really, more just tack the gasket to the waterpump itself. At least thats what the guy at the auto shop told me.

Looked something like the below. I was browsing their website and apparently they have a special waterpump tacking sealant but my auto store didn't carry that or that would've been what I bought.

 

Yes was thinking most would just use the sealant as a gasket holder.
I have a new unopened tube of loctite blue maxx. It's just a silicone sealant.
If the only reason is for using it is to hold the gasket in place then I doubt I'll bother with it.
One less thing to worry about failing down the track.

 

I dunno I think it would be pretty tough to align the gasket on the pump against the engine surface without tacking it.

 

Nah, easy as.
Just partially insert two bolts into the pump body, put the gasket on the back of the pump, and install.

Mind you I havent done an 850 pump, (yet) so in a few weeks I'll know for sure.

 

Oh OK that makes sense

 

And don’t forget to apply some thread sealant onto the bolts. Some new bolts seem to come with sealant (red) already applied.

Thanks for the heads up.
Just checked the new pump kit (gen volvo), new bolts are pre treated with a pale blue/green thread locker.

All things being equal, I should be set.

Thanks all.

 

Enjoy new water pump!

Ta.
More looking foward to not worrying about the timing belt though.

 

Update 25-12-08 (I have no life )

Yay, almost all done.

Today I did; (took about 6 hours with a lunch stop between)
Timing belt, water pump, serp belt, tb idler, tb tensioner roller, spark plugs, coolant.

Tommorow is oil and filter, and a minor auto dump and refill.

Original idlers/pulleys were a bit rough or loose (180,000K).
Someone had used a marginally longer serp belt at last change (before my ownership).
Water pump was showing signs of leaking from the welch plug.

I did use the thinest of smears of gasket goo (Blue maxx) on both sides of the gasket.
Idles sooooo much quieter, I can actually hear the injectors ticking now.

Only thing I'll add to the timing belt change is,
When trying to line up the marks, I pulled the dizzy cap and went for #1 firing.
Made the whole timing job so much faster and easier.
That crank notch is an absolute prk to see.
Hardest part of the whole job was swapping the water pump, 7 bolts, all in hard to get at spots.
I love my Stahlwille 1/4" set
