celica overheated., Fan/Fan switch/Thermostat? Options

[Badkarma]

my gf's celica overheated today and by the time she realized the temp guage topped out, she was home and the car was steaming. when i got home from work i checked the coolant, it was low so i filled it and it isn't leaking. (not enough to notice) so i had her start the car and the fans didnt turn on at all while the temp guage topped out again after about 5 min.

i figure its probably the thermostat, Fan Switch/Relay, or the Fan itself. am i on the right track? how hard is it to pull the thermostat or fan switch/relay?

Thanks, Erich

well, the auto that was fixed broke down the other day. just needed coolant. its either leaking(which i cant find a leak anywhere.) or its burning it up.so my gf is driving it around now and just refilling the rad every few days. hope its not a headgasket. but i guess it would be a good learning experience.

i bought a radiator today for the 5spd. i looked yesterday and it doesnt have any coolant flowing through, its full, but the coolant isnt moving. im thinking the rad is clogged up somewhere. when at operating temp, one side of rad is hot as hell, but the other side is... not so hot. just warm.

ill replace the rad. this weekend and ill keep you posted.
