Okae everyone might be tired of this questions but i can't find the archchived answer's so here it goes ,what are symtom's of a blow headgasket? the reason im asking is because I been having a overheat problem and so far I have swapped out my stock radiator for a all aluminum one flushed the coolant system got new obx radiator hoses ,change the thermostat (did not get the offical toyota one though) ,and also water pump, and still after 50 miles of driving at 70mph I'll come off the freeway and start to get cold air out the driver side vent and heat off the others then the needle climb to the H and the coolant feels the resovoir and then speels out the overflow tube and i get cold air out all the vents ,I don't get white somke pouring out the exhust or anything that bad just been getting overheating problem and am running low on answers anyone can point me in the right direction please....

btw.1992,toyota mr2,non-turbo,2.2 5sfe engine with about 45,000 miles on it brought the engine from a toyota engine supplier also had water pump and timing belt replaced

have you checked to see if the radiator fans are working?

[ryunosuke]

yup pulled the sensor plug out and they both came on strong

sounds like you didn't bleed coolant system properly...

[MR2Jedi]
