I have a 06 z71 and the tube that is pressed into the top part of the water pump is seeping, not really leaking around where its suppose to be pressed into the pump itself. Truck has 62,000 on it. I don't know how long its been doing it, but the coolant was a little low, so I added more.

To me, this seems to be such a small problem, I don't want to really put a whole new water pump on it. I was thinking about trying some kind of coolant sealer that you would mix with the antifreeze. Any of you have any recommendations? With the truck being as new as it is, I'm a little hesitant about putting a radiator stop leak fluid in it.

Can someone point me in the right direction?

 

the right way is to replace the water pump

 

^ agree 100%. Either replace the pump or live with the leak until it gets worse, just remember to add coolant every now and then.

 

i would never use the stop leak, plugs up radiators and heater cores
