It's a reverse cooled LT1, so the thermostat housing is on top of the water pump and once you remove it... you dump coolant all over the Opti Spark. LTX's take a bit of time to bleed the cooling system completely because the coolant entry path/point (water pump) is so much lower than the cyl heads, which cool first. Andy- This is the proceedure I follow on LTX's: Engine COLD. 1. Remove the cap from the surge tank and pack a few paper towles/rags under the thermostat housing. 2. Start the car. 3. Open the thermostat housing bleeder screw and let it vent as the engine warms up. Pay attention to the coolant stream as the thermostat opens... run engine with the bleeder open and add coolant to the surge tank as nessecary to keep it full. Once you're pretty sure it's all bled out (steady stream of HOT coolant from the bleeder) close the bleeder, make sure the surge tank is full and put the cap on. Fill the over flow tank to the hot fill line and let it cycle the fan a few times before you go out on the road. Should be good to go at that point but some are real SOB's, so you may need to repeat the proceedure again once it's cooled off. Will |
