Hey, I just got the timing on this 2000 S70 done at 104,000. Now, I am new to the B5000 engines so I didn't know that it is best to replace the water pump and the belt together since they are so close and easiest to do at the same time. Lucky for me my mechanic was nice enough to tell me AFTER he had finished the belt and told me to come back with the water pump. So now I have to pay the labor again (not too happy about that) and I am wondering should I get the Volvo original part or any after market that fits?

My concern is: Is this pump gonna fail, ruin my engine and make me have a bad day? Or what is goning to happen? I have heard that if you don't change the pump with the T-belt the new tension will stress the old pump and cause it to fail soon after like 2 or 3 months. I did the timing about 1500 miles ago and I am getting kinda nervous.

He also told me AFTER he was finished with the belt that I needed to replace one or two of the tensioner/rollers on the belts. I did replace the mechanical tensioner on one of the belts so how many more of those are there?

Thanks in advance for the help

John

When I had my timing belt done I went ahead and had the water pump done at the same time as I didn't want to have to have it all taken apart again.

Since yours is already done and your waterpump isn't leaking I would let it be. If it starts to leak or you hear it failing then you will have to pay anyway to have it done.

I wouldn't waste the money to have it done now. I would have it changed when you do the timing belt next time if the original pump is still there. The OEM pump is the way to go.

Either way, if your water pump DOES fail in the future, spend the couple extra bucks and have a new timing belt put on it and go 105K from that point.

I have never heard of a new timing belt causing the water pump to fail though.

Hope this Helps

The t-belt tensioner is always suppose to be replaced with the t-belt at 105K miles as stated in your maintenance book.

As for the water pump, unless it's leaking there's no need to replace it. They usually never leak. If it was leaking and the guy doing the t-belt saw it leaking then but failed to tell you at that time, I'd say the labor is HIS problem unless you declined the repair at that time.
