: Coolant Leak....

03-20-05, 02:41 PM
Changing the oil today I noticed a coolant leak. It looks like it is coming from the bottom of this part pictured with the arrow. It looks like some sort of valve??. Im pretty sure the dealer replaced these several times in the past looking back at some of my repair sheets it says (valve coolant) Can someone help me identify this part?

That's the electric "Auxiliary Water Pump" and it works with electric fans to aid cooling by mixing the water in the radiator.

Would anyone know the part number for this so I can look it up on GMpartsdirect?? I cant see the number and I dont want to take it off until I have a new one.

Thank You!!
