- 1991 4 cyl overheat problem
- Posted by Seamus J. Wilson
Where is the switch that turns on the electric radiator fans located on the
engine?
Thank you,
Seamus J. Wilson

It should be on the lower end of the radiator. This on/off switch
measures the coolant temperature and turns on the fan. The switch
should be test, and for a 91, the fan should be tested (using the
battery directly). The brush in the motor may be worn out or the
switch gone bad.

Use Toyota Red (not Pink) coolant with distilled water every 2 years,
probably time for a thermostat/gasket, radiator hoses, bypass hoses,
radiator cap as well.

Besides the fan switch/fan motor, a 91 could also have other causes,
such as head gasket issues, plugged radiator, etc. So consider a
complete check unless you're sure it's the swtich/motor.

I removed the radiator, bad leak. No switch in radiator. Must be some
place in block, but I can't locate it.

Hey Wilson,
I had a similar concern with my 1992 Toyota Camry and I
subscribed to ALLDATAdiy.com and it has been very useful. I am handy
and like to do things myself and this subscription gives me diagnosis,
repair, TBSs, recalls and labor times. I hope you find it useful -
it's pretty cheap considering the information comes directly from the
manufacturer.
Check it out - I copied the link below for you.

The last time the free guide was down, but I just pulled it up. Looks
like the switch is in the diagram:
http://www.autozone.com/shopping/repairGuide.htm
Under "Engine&EngineOverhaul" -> "Radiator" -> Figure 1
In the diagram you should be able to see "Water Temperature Switch".
Do you have this? Yours should be a 2.0L 3SFE prior to the switch-over
to 2.2L 5SFE engine? Haynes manual at Pep Boys should also be able to
point you there.
(The following is the URL to the figure, but may be my search-specific
link)
