Up date on my truck, it died on the highway with fuel rail leak, I had it towed into GM, I had to replace the left side fuel rail blow off valve. Had them do a pressure test for the anti freeze leak, turns out it not a head gasket, it’s the oil filter housing/coolant adapter housing that was leaking. Also replaced a couple of power steering hoses. The Bill was 3700.00$
+ tax’s, not 8000.00 as first quoted.

There’s no way, I would have been able to do the work, I am on crutch’s with ham string tear.

Interesting. I had to have my oil filter/cooling adapter replaced under warranty on my 2016 last fall because it was causing low coolant light. Never did see a leak on the ground in my garage.
