As of late my gas mileage has been lacking. I'm wondering if it is being caused by a bad coolant system thermostat. Its acting like my 77 bus did when the cold start valve wouldn't shut off. In looking at the "pro manual" it say's cold start is now handled by a longer injector duration as determined by the coolant temperature as determined by the coolant temperature sensor. I've noticed it is taking quite a while to get to operating temperature (if at all in our frigid Utah temps). Do you concure that a new coolant thermostat is warranted? Bentley is not very discriptive in this proceedure. The schematic seems to indicate all you have to do is remove the Breather Valve assembly and the thermostat is underneath. How much coolant is lost in doing this? Do I need to bleed the system after replacing the thermostat?
