Hi all I have a c5 2.7 diesel overheated even though the gauges didnt show high
The engine stopped cut/out coolant on the ground , looks like a slow coolant leak going unnoticed, Low oil pressure came up just before it stopped .
Towed to a dealer , now it refuses to start . Maybe the motor is cooked
They can’t diagnose any problems because power is not going through the ignition. After 6 weeks I don’t think they know what their doing . IE no codes
Any advice Including a crusher would be welcome .
