PissWhisk posted:I did something slightly retarded. My car is LS2 powered and the heater control valve had failed, so as a temporary fix I just used one of the existing coolant hoses and made a loop from the input to output of the heater circuit on the water pump. There's a remote possibility that the high spots of the engine (the heads, basically) had air pockets and weren't getting cooled effectively, and could have warped. Like I said, though, it's a remote possibility. If you were starting from a fully cold engine, the heads didn't have warm coolant flowing through them and so were only being heated by the top of the combustion chamber, so they might not have ever gotten up to temp, let lone dangerously hot. I'd still keep an eye on things; look for further overheating (though your temp gauge is probably a glorified idiot light so don't rely on that), coolant loss, oil loss, or coolant mixing into oil (check these every week or so right after driving, the last one will show up as oil that looks like cappuccino.) Watch for a month or two, and if none of those show up you should be fine. DO make certain that you burp it very well after refilling the coolant. Elevate the front end and let it run with the radiator cap (or reservoir cap if it doesn't have the former) open so any air pockets can bubble out. A good rule-of-thumb is that the level in the radiator shouldn't drop if you give the engine a rev, if it does there's air in the system that's getting compressed; if your car has an electronic throttle you may need a second pair of hands for that. You can stick the neck of a funnel into the opening so the funnel contains any coolant from spilling onto the ground.
