Re: Unusual Coolant Issue
Hi Don,
The air bleed system should be functional. In my opinion there must be coolant flow from the air bleed inlet into the surge tank. The cooling system on the LT5 is complicated. I suggest sticking with fundamentals and getting the air bleed system working. It might be clogged. There is a detailed description about how to find and fix clogged air bleed lines in the Heart of the Beast issue number 31.
A thermostat that is stuck open or closed will not have any effect on the flow of coolant through the air bleed system.
Best of luck.
Marc
