Does anyone know where the water temperature switch is on a 20 valve 4A-GE?
I'm talking about the switch that sends a signal to the fan relay once the temperature reaches a certain level so that the fan can turn on. My car no longer has the fan relay box in the engine bay so I need to wire the coolant temp. switch wire to a hidden relay myself. Once I can figure this out I can put my car back together.

Coomer,
The sensor is the one that is not shown in the pic above, it sits sort of at the end of the thermostat housing. It keeps the circut grounded when the engine is cool, and when it gets hot it actually opens the circut. (This causes the relay, which is normally closed, to close and therefore turn the fan on.) -Doc -------------------- -Dr Tweak, 6GC's resident engine swap wiring expert extraordinaire Click here to see my swaps drtweak@phoenixtuning.com |
