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

wouldn't that show up in the oil tho?the car takes about 20 minuites to start getting how when cooling system if completely full. and still, the only signs of leakage is whats going into the overflow.It didnt do this to the girl who i bought it from until jst before i bought it. and she drove it to miami from tampa just fine on perfectly clean oil.

just took it for a test drive after over an hour of cool time. and it was boilinf before i even hit one mile.

were you with her when she drove that far?

search more... its not necessarily that the coolant mixes with oil because in this case, some of the exhaust gas are push through the water jackets or head gasket and creates pressure build-up in your cooling system.
