No power and no fans
Asked by Cdavid92 Sep 29, 2017 at 10:40 PM about the 1992 Toyota Camry LE
Question type: Maintenance & Repair
I have a 1992 Toyota that i pulled the 2.2
out replaced all the oil seals and replaced
the engine. Now the problem... as i was
filling tbe coolant the fans never turnes
on and the car acts like it has no power.
It starts perfectly and idles nice,but when
i hit the throttle it barely revs up and
dosw not want to move. With the coolant
issue .. it acts like the thermostat is not
opening the temp gage is almost to the
hot side, the fans don't turn on and the
heater hoses on the back side of the
engine are still cold, so there is no
coolant flow...any one has any ideas I
would really appreciate it, Thanks

I did check the sensor and replaced it. I thought about tbe thermostat being stuck, but that wouldn't stop my fans, would it?

Fans not directly linked to thermostat but if stuck closed the engine may be hot but the radiator is not.

You unhooked a lot of wire connectors I would overlook it, step back and think for a minute, then go back and look around, retrace your steps and see if anything is left unhooked or a pinched wire, broke connector, ect.

Let fans run long enough to cool engine down if it will, if top radiator hose stays hard and it is running hot then you know the thermostat is bad or put in backwards, if that is even possible on that model.

Put thermostat in water and warm it up to see if it opens, make sure its not clogged up with too much used gasket sealer.

Radiator cooling fans are controlled by the computer. Information collected from the coolant temperature sensor and from the air conditioning control switch provide the fan control with information. So turn on the a/c to see if the fan or a/c fan will come on if you have two fans, and test the coolant temp sensor or hook it back up or fix connector or wire to/for it.

There is a radiator fan relay too, may end up finding it and replacing it. Of course I would check all fuses and grounds too.

Or if all else fails you can buy for under $30 a FOUR SEASONS 35879 Temperature Switch; Premium Adjustable Fan Controller; Push-In Type.
A thermostat that is stuck closed will impede the fans if one side of the thermostat is hot and the other side is cold. And the cold side has the temperature sensor
