I'm hoping someone here has experience or some knowledge to share.
Driving home today with maybe 2k on trailer. 5 hours running 75mph average. Got home and noticed wet inner fender liner passenger side. Narrowed it down to the coolant overflow tube. Started reading forums and sounds like head gaskets. Could be rad cap or thermostat, but since it's my luck, it won't be easy or cheap like that.
1 thing to note...I recently installed an edge programmer. When I got fuel an hour from home I apparently switched from level 2 to 3. I guess while I was looking at some info while waiting on the slow pump. May or May not be a factor but I'm sure it's not ideal.
Any thoughts? Has anyone done gaskets on these trucks? I'm reading on Duramax forum people pulling the engine to do the job!!!
Apparently I should be able to squeeze the upper radiator hose in the morning and if it's still hard/ pressurized, that's a tell tale sign of head gaskets??
