Try when engine is cold, start engine andremoving the radiator cap. Observe if the water level drops. Which im betting it will. I would also wait til it reaches operating tempuratures" when the thermostat opens". It might drop even more. I on the other hand have a bad head gasket and my antifreeze is being sucked out the engine exhaust pipe slowly. There are quick fixes, radiator stopleaks, that only work for a while and the problem returns. I just dont have time to tear the engine apart. Im going to try this sealer which contains real ceramic. It might do the trick. Why didnt chevy make the heads 3 inches thick between the water tubes? Uhg
Oh, and I'm gonna check my 89 for exhaust gases. After that, I plan on flushing all the old coolant out as I've got some crud build up and what appears to be some oil. Though it may not be oil and just from the crud.
Since I'll just have to use the radiator to dump the coolant when I flush, I was thinking of draining the radiator, and remove the thermostat, Then bolt everything back up and do the drain/refill/drain/refill to flush all the crap out. Does that sound like a good idea to remove the thermostat for my home flush? I figured then, I wouldn't have to wait for the car to heat up so the thermostat could open, and then I wouldn't have to wait for it to cool down when I do the drain/refill deal.
