I have a 1995 850 turbo. If the waterpump was not working how can I tell. The car does not overheat and the heating blows hot on the interior. Is there a home test I can do to test the pump. I installed a new thermo a couple of months ago and when I changed out the tensioner and belt I did not do the pump because the forum said they were very durable. The car only overheated once this summer and I believe there may have been to much anti freeze and the cap was a little loose.


Any thoughts.

 

If your water pump was not working you would know, the water pump failing leads to blown head gaskets and what not. I think your engine would be running pretty rough if your water pump wasn't working. But wait for a pro to get on and verify. That's just my 16 cents.

 

when a waterpump fails is normally spits/leaks coolant all over (often quickly emptying the radiator) the place, and if you dont notice the smell, the radiator warning lamp will come on when the expansion bottle gets low. and if you miss those clues... the temp gauge may climb, but it will be too late then as the temp sensor is now dry and will need a really eff-ing HOT block to make it wiggle.

 

How many miles are on the pump? I am changing my out in the next 5000 miles when I do my timing belt. It will have 200K miles on at that point.

 

123,000 is there much water flow normally. It does not leak water at this point

 

That's really early for a waterpump to fail. My car has 214k miles and no failage.

 

+1, you are still fine. You normally want to change them out around 180K.

 

meh, its a volvo, i dont replace it till it makes a noise or goes "SWEALANG!". seriously though, i usualy dont fallow what people "say" you should change it at. change it when the time is right.

volvo says do wheel bearings every 80k..... screw that.

 

lulz. Same here. Except the timing belt, that's something I don't think you want to wait until it goes, how do you say, SWEALANG!

 

swea'-lang different word for SHINK! (like a timming belt breaking... SHINK!)

 

SHINK! Followed by @#$% !!!!!!!
