\015 I have a Toyota 1988 4 cyl. 1800 engine . It was totally rebuilt , new radiator, new sensors , direct cooling fans and gets really hot when climbing hills. What could caused this ???\015
Check anti-freeze level first. If anti-freeze level is fine check the thermostat, most likely it's sticking and not allowing the fluid to cycle out of the engine and into the radiator to cool off. After replacing thermostat if problem still presist it could be a blocked coolant passage in engine or in cylinder head. U said it's been completely rebuilt, I have seen were the person that rebuilt it installed the wrong head gaskets and that could be blocking the coolant passage as well. Mind you, a blocked coolant passage is the worse case scenario. I took for granted that you already checked to see if the fan is working if it's an electric fan.
