Hey guys, today I picked up a 2008 Silverado crew cab 4x4 3500 LMM.
It was a work truck and the company took it to a shop after the low coolant light popped up. They told him they thought the passenger side head gasket was the cause and only slowly leaking externally.
There is no coolant in the oil, no coolant leaking on the ground, and does not smell sweet like it's leaking into the exhaust/combustion chamber.
Anyways I bought the truck today and it did not appear to lose any coolant on a 6 hour trip home. It's actually a very powerful truck. I parked the truck and about an hour or two later went and checked the upper radiator hose and it's squishy. Also when the truck is ran there is no pressure in the degas bottle. The cap always comes off with no pressure. No bubbling either, even at idle. I crawled under the truck and can see signs that there had been in the past a coolant leak onto the down pipe, but nothing is wet currently. I've been doing a lot of research and a lot of people seem to find this gasket to be a cause of a leak in that area.
Does the LMM have this gasket and would that make sense for my issues?
The coolant level did not drop any today but I will continue to monitor it this week.
