All,

What is the recommended water pump replacement interval?

Thanks,

Matt

At the 200K timing belt change interval, in most cases. It also depends on the type of antifreeze used and frequency of flushes. The pump is metal, unlike the plastic pumps in BMWs which last for 40-50K miles.

The dealers and parts suppliers encourage owners to replace the pump at every timing belt change. More money for them. They now also include cam seals, which is labor intensive and in most cases not necessary.

Don't know the replacement interval but have a '95 855 with 201K miles and the original, non-leaking water pump. Yea, I'd say they're pretty robust.

I am pleased to learn that the WP on these motors is long lived. I am in the middle of changing out the TB on our 2002 S40. When we bought this car two years ago it had less than 25k on the clock--had been owned by a li'l ol' lady who had passed away three years previously. Before even starting the motor I pulled the TB top cover and examined the belt which looked to be in very good condition. Checking service intervals I found the recommendation to be 168 months---14 years! Now with just under 55k I checked again and found the back side of the belt to have very tiny spidery web cracks--obviously time to change it. I was concerned about the WP - which by miles, at least, was young but ordered one when purchasing the belt just in case.
My plan is to examine the original WP and check for these conditions---Does it rotate smoothly with no indication of a bad bearing?---and--does it have some resistance to rotating due to the seal still being tight? If those conditions are good I will probably leave it in place rather than install the aftermarket WP purchased. -- Dave

Don't know Volvo's recommendation. Owners manual? or internet search should turn it up.

What I do know is the water pump on the 5 cylinder engine is pretty robust. The general consensus here is they normally last over 200k. I changed mine on my 95 855 at 213k when I did the timing belt and tensioner. It wasn't leaking but I felt it was the ideal time to do it since I was doing the t-belt.

Jwalker,

Your post goes along with what I believe I have heard else where, but I wanted to hear from the board on this one.

I just want to make sure I catch them before they fail as I don't want to replace another head ever again on an interference engine!

Thanks much,

Matt
