step by step: early this morning.

open up the radiator cap.

start engine.

no oil mix w/coolant, neither does reservoir

air bubbles blow out from neck of radiator

check exhaust; no white smoke

upper hose gets hotter faster than lower hose, eventually lower hose got hotter too

Note: car doesn't overheat driving around town. it only overheats when i go for a long drive like 2 hours or more.

t-stats been replaced twice and flushed out the coolant twice. new radiator cap.

what is the problem here?

 

sounds like you have to bleed you coolant system. doesnt sound like a headgasket.

thanks.

 

search for bleeding coolant. also, on you thermostat housing their should be a bleeder screw. take a 10mm socket/wrench, i believe, and slowly open the bleeder valve. a mixture of air and coolant may come out. be careful its very hot. i use some paper towels to catch the coolant as to not get it everywhere.

 

take off the radiator cap, and let the engine run. Occasionally rev the engine up a little bit (not enough to throw coolant all over the place). That's about it. Once you stop seeing air bubbles coming out for a while, it should be good.

If you have a bleeder screw on your thermostat housing, you can use that instead. You'd get a hose and some kind of clear container. Put the hose over the engine of the bleeder screw and stick the other end in the bottle. Start the car and let it heat up, then crack open the bleeder screw occasionally to let air out, close it again to build up pressure; just like bleeding brakes.

wow guys, that just sound so complicated. i hate messing with coolant/antifreeze and car battery.

i heard a simple way to see if you have a bad HG is, empty out the coolant in the reservoir and drive the car and rev it. if coolant flows in there it's bad?

is that a way to test it?

 

i called to bullshit around a couple shops in town and they quoted me 35-45 dollars for a compression and a leak down test. each!

 

haha i sound like you do when i first started my engine swap. people are cautious of what they do not know/understand. take a detailed look at your engine bay. see if you can print out a labeled picture and have fun educating yourself. its a good feeling working on your own car. you are able to say "hey, i did this". let alone save some cash.
