shockx5 Posted January 7, 2008 Report Share Posted January 7, 2008 I'm fighting a small coolant leak somewhere in the system. Has anyone ever used/heard of GM cooling system seal tabs? Quote Link to comment Share on other sites More sharing options...

Has anyone ever used/heard of GM cooling system seal tabs? make sure its not your water pump going out........water seeps through the weep whole on the pump when its time for a new one.

I think that may be it. I'll have to check it for a leak. The pump pulley has been whining for a while as well (just confirmed this today. Thanks!
