Question about 1991 Toyota Camry
Engine Cooling problem 1991 Toyota Camry 4 cyl Front Wheel Drive Automatic 120000 miles The car has run hotter then usual. Checked all the obvious and everything good. Left running to check if fans kicked in and noticed that they do not start on time as before. They both did turn on but the temperature reached 3/4, instead of 1/2 as normal, before they kicked on. The temperature does immeidately drop but I did not feel conformatable that it takes a higher temperature to start the cooling fans. This is happening on a cool day (55-65F) or on a hot day (85-95F). Please advice possible solutions and location of thremostat/switches on engine. Thank you.
The cooling fan is controlled by a temp switch in the bottom of the radiator, try6 replacing this switch.

Switch ig. on, ground the sender unit wire for about 3 seconds see if the temp. gauge moves, if so change sender unit, if not then it is a faulty gauge reader.

you will need an electric fan fitted to the radiator and bear in mind that you will need the appropriate voltage reading etc,so you need the right power source.Also you need to consider a thermostat fitted in the cooling system unless you want to run it on direct power.For any questions,please ask.

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.

Did the dealer check the crakshaft sensor? it sounds like the timing is shifting causing the misfire.
the heat can cause intermitent faults maybe not long enough for the computer to register the fault with a code.
And as a possiblity the coil pack may be arking out somewhere, has this ever got wet? or cold recently?
