Help! Car over heat!

Clear muna natin. Sorry hindi pa ko nakakita ng engine bay ng ride mo. Ilan ang auxiliary fan dyan sa likuran ng radiator? (normally dalawa. one each for radiator and condenser).

Kung dalawa yan at isa lang ang nag on/off pag umaandar ang aircon then ang fan na ito ay for condenser cooling. Dapat ang isang fan pa ay on/off ayon sa temperature ng cooling water ng makina. Possible na ang radiator fan ay hindi umaandar dahil sa electrical problem, maybe fuse, relay, temperature sender/switch or the electric motor itself.
Kapag dalawa ang naka-install na fan at isa lang ang gumagana (condenser cooling fan) sigurado na iinit ang makina mo kasi hindi kaya ng isa dapat dalawa ang tatakbo. May mga toyota xl dati na pag patay ang aircon ang engine temperature ay tumataas kasi hindi kaya ng isang fan palamigin ang radiator (maybe partially block ang air passage sa radiator) lalo na tag-init at sa gitna ng traffic.

Baka ganito ang problema ng car mo.

you mentioned your temperature gauge halfway. this is normal, however, the transmission may have a slipping problem. at this age of your car, specially if you had overheating problem, may have already damaged or worn your clutch packs and brake bands in your transmission. what you can do to (hopefully the results are negative), is to perform a stall test. do this with the engine at normal operating temperature, vehicle at a level surface, wheels chocked, then while applying the service brakes and the parking brakes, place the transmission in D range and rev the engine up while observing the tachometer at what engine rpm the tach stops. record the result and repeat procedure in reverse after the engine and transmission has cooled of a minute or two and record the stall speed again.
