1994 toyota 4runner 3.0L overheating?
ok so i have a 1994 toyota 4runner and for some reason i have an overheating issue ive replaced the radiator with a upgraded silla all aluminum one, new fan, fan shroud, fan clutch, done a complete coolant flush, ive done head gaskets twice, today i did a block test to see if they are blown again an it passed. but tomorrow im going to do a cylinder pressure test to completely eliminate head gaskets. it does it at high speeds only when i have the A/C on it does it after 15-20 mins of constant RPM around 3-4 grand. but i can drive all around town with no problem... another thing that drives me crazy is for some weird reason when i see my temp gauge start to go up it decided to become really sensitive to power drops, for instance if i were to roll my window up or down the gauge moves up towards the hot side, and when the a/c is on it does the same thing if its on high the gauge goes higher... ive checked all the grounds an replaced ones that looked bad but still no luck if some one could help me out that would be great thanks!!!
