How to spot a water pump failure- with pics.

You can spot a slow leak by looking for signs of dexcool leaking and drying on the timing chain cover.
Heres an example- note the trail of dry coolant (white residue).


Another thing to look for is the signs of coolant being flung by the spinning water pump pulley.


Another sign to look for is drops of coolant that has not dried.


Another sign of the leak is a little more severe- drops of coolant on the floor. (the other spot was much bigger- about 8 inches wide).
This is only 1 drop


And- if you have a much bigger leak- signs of coolant on the vehicle.









here are shots-- with the wheel turned outward-- you can clearly see coolant

Re: How to spot a water pump failure- with pics.

Most people report no failure until theyre in the shop for something else- and the dealers tells them its leaking.

Others- will leak for a while- and suddenly fail. Some leak- and are pressure tested and pass- only to fail a while later.

In my case- it was pretty quick.
Mileage- 39,400.

From one of the pics above its possible it has leaked for a few days.
But it cant be more than a week old. I checked it (visually) last week- yup- I get down and look at that area often.
I drove the vehicle about 100 miles yesterday- and there was no coolant on the driveway. I also smelled nothing.

Today I visited my sister- and strangely- we HEARD the failure. It sounded like bad bearings. Like an alternator going bad(if anyone is familiar with that sound). It lasted for about 30 seconds- went away- and then came back....
At that point I popped the hood- and looked under the car- to see the 2 round signs of coolant- oily looking spots (at 1st I thought- PS pump?).
The noise then went away. I drove home about 2 miles and took the pics above.
The coolant reservoir was at the FULL mark.

Re: How to spot a water pump failure- with pics.

That's too bad. That is definitely an early failure. Is the the water pump is covered under the 5yr/100,000 warranty right?

I'm sure you will keep us posted on the details of the repair. Not something I want to read 1.5 weeks before I embark on a 5,000km trip.

Re: How to spot a water pump failure- with pics.

I just topped up my coolant this weekend. The Traverse had sat for 2 days without being driven, so I did my fluid checks. I added about 1/2 a cup to the overflow tank. Not much, but where did that 1/2 cup go?

Re: How to spot a water pump failure- with pics.

my traverse got dirty- when I drove up to the snow about a month ago. didnt drive thru snow- but there was alot of dirty water/muddy leftovers.

The water pump should be covered under the powertrain...100K

Well- they must be driving it to a service bay or something---
I Just received my Onstar email.... so I know the vehicle has been started.

I dropped the car off at the dealer at 530-545 am.
