Barney Posted November 8, 2009 Report Share Posted November 8, 2009 SS Members, I have a small leak in my coolant system. It has lost about half a gallon since July. I thought it was most likely the valve on the Radiator but that was fine. Seems to be from the bottom of the Water Pump. Has anyone else had this problem. Is it a common issue. I am going to try a stop leak liquid before I put on a new pump. Thanks IN advance, Barney Quote Link to comment Share on other sites More sharing options...
BlueAKSSS Posted November 8, 2009 Report Share Posted November 8, 2009 If its the water pump going out I wouldn't recommend using stop leak as I have had some bad experiences with it. The water pump is really easy to change on these trucks. Also check your hoses going to the water pump as mine had a lose heater hose causing a leak. Good luck!

Fireman31 Posted November 9, 2009 Report Share Posted November 9, 2009 Stop Leak is a no-go with water pump issues. When you start getting coolant leaking from the weep hole, that is usually a sign that the pump is on the way out. It is in your best interest to replace it....

Tzer Posted November 9, 2009 Report Share Posted November 9, 2009 NOOOO Don't use Stop Leak! That'll just put that crap through out your whole system. Get a new pump.. Not a difficult change. Quote Link to comment Share on other sites More sharing options...
wody Posted November 9, 2009 Report Share Posted November 9, 2009 make sure it is the water pump and not the gaskets. i've seen too many replaced at work, when the gaskets were actually at fault. Quote Link to comment Share on other sites More sharing options...
Barney Posted November 9, 2009 Author Report Share Posted November 9, 2009 Alright thanks guys. I had not heard of any problems with the waterpumps. I thought it was just me or maybe something worse. Did a compression test and that looks good and the leak is on the front of the engine. That would lead me to think its new pump time. This one does have 90k on it!

budhayes3 Posted November 12, 2009 Report Share Posted November 12, 2009 The water pump gaskets are very common failures on these engines, and they're less than $20 for the pair, whereas I have seen waterpumps go for $400+. Haven't heard of too many water pump failures. If the coolant isn't coming out of the weep hole or from the front seal, I'll bet that it's the gaskets between the pump and engine. They may not even leave a messy trail behind... Quote Link to comment Share on other sites More sharing options...
red454 Posted November 13, 2009 Report Share Posted November 13, 2009 I just replaced the water pump gaskets on mine as I had a little coolant leak. The gaskets in these trucks are metal with a rubber ring on the inside. Any little oxidation and the gasket pulls itself apart and causes the leak.
