I have a 95 GMC Sierra, 350 motor, and i am leaking coolant. Checked my oil for the "milkshake effect" to see if head gasket is gone. Oil is okay. Checked upper and lower hoses, both good. Coolant is coming down the front of my engine, running along the front of my oil pan, and onto the ground. Water pump is all I can figure, any suggestions?

Also checked the Haynes book, it suggested checking the weep hole, but I can't seem to locate it. Any info is welcomed. Thanks.

 

The weep hole is a small little hole that is under the water pump shaft. You may have a bad seal. Water pump seals wear out after a while.

Lower intake gasket!

 

A 95 is still TBI and only has an intake gasket from the intake to the heads. It is a possibility though. They did not have the issue like the 96-99 Vortec motors however. Check to see how high the leak is coming from. My money is on the water pump...but what do I know?

 

My vote is on the water pump

Changed the water pump today (and removed about 3 layers of skin off my knuckles ) and that seemed to fix it. No leaks happening anymore(for now), thanks to all who replied to my post.

Thanks again!!
