i have taken it to a garage round the corner that opened last week - only one in driving distance for me. i can't even make it to the closest reasonable parts store which only delivers to garages anyway. they are still moving equipment and will do a compression test for me when the gear arrives today. replaced the thermostat yesterday - no change. the old one looks pretty much new (gasket too) which i'm hoping is a sign that i didn't do any major damage on the overheat. checked the fan blade and there is some resistance to it turning so i think the fan clutch works ok.
i'm hoping it is the water pump or an easy-to-find clog somewhere. would coolant still circulate even if the heater valves weren't opening? the radiator looks to be in excellent shape and all the hoses seem almost new. btw the ac is obviously screwed and i've never used it. i checked the hoses when it was running again and the top ds hose is hot near the thermostat but cold near the radiator. there are no coolant leaks that i can see.
i've never experienced an overheat before and i am terrified that i let it get too hot. the car still seems to run great otherwise - exactly as before. the needle got about half-way through the red-zone (i was REALLY stuck in traffic) the one time and since then has never gone above the 3/4 mark. there were no clouds of steam and i didn't smell anything burning or melting but it did pop the safety-cap on the expansion tank.
it warms up normally, but just doesn't stop heating up - it happens pretty quick, and i only get cold air through any of the vents.
if anyone thinks i phXXkd the HG or anything else i sure would like to know - any ideas would help. sorry this is so wordy i'm just trying to include anything pertinent i can think of.
