Coolant Leak...

[CumminsAholic]

Here's an interesting one for you guys. I have a coolant leak but my radiator is never low. I filled up my overflow bottle this winer on the way to a race and when I got there my coolant was all over the ground under the truck. I looked for the leak =, but couldn't find it. Checked it and the radiator as full, but the reserve jug was empty. Drove it home and no more leak. If I fill up the reseve tank it doesn't leak. Today it was pretty warm here and it leaked again. Probably a half quart, then it stopped. I figure since it's hot it blew into the overflow bottle and leaked out. Here's the problem. I can't find the leak. It's not coming from the bottom of the overflow jug. It's leaking on the passenger side right close to the radiator, and drips off of my frame. Anybody else have a problem like this? I'll check the overflow again, but I know it's not coming from there. Like I said though the level in the radiator is never low and it doesn't leak unless I top off the radiator or fill up the overflow jug. Thanks in advance for any tips.

Take it in and get it pressure checked. Should see something then.

Had the same problem and noticed what looked like a small rust line from the thermostat housing matting area. The dealer changed the gasket and thermostat. Been fine ever since #ad

BD,

For future reference, there is no separate gasket for the thermostat housing. There is a gasket that is integral to the thermostat. When you change the thermostat, the seal between the thermostat housing and the engine is renewed.

Proper draining of old coolant requires removal of the thermostat housing and thermostat. Have a new thermostat on hand before you change coolant.
