Question Asked: coolant leak
April 08, 2009, 12:41 PM
Tthe truck uses and leaks coolant towards the front of the engine. About a cup every 2 months. I keep hearing about a "cold engine leak" with these models. 5.3L. Something about new style gaskets that will leak when the engine cools off. Checked around the water pump and the weep hole is clean.
