Alltrac engine overheating and losing coolant

[bhawkins]

Anyway, my alltrac started to overheat an then leaked the coolant out, as i examined things beneath my hood i found out that my top radiatior pipe is punctured(no wonder i lost the coolant). As far as overheating goes i believe my thermal switch (the sensor that starts the cooling fan on) is broken so i bought a new one, while i'm at it i got a new oil and fuel filter. I got no trouble with the filters, but my thing is, i can't find the thermal switch. I even took out the intercooler but i can't seem to find a plug-jack that would fit my new switch. The switch by the catalog belongs to my car.

If anyone knows where is the thermal switch on my engine or even has a pictureof it's location, i'd really appreciate it. Thanks.
The car is 1990 Celica Alltrac, 3S-GTE, ST185, chassis number is JT2ST88P2M0011371

First off, if you have a Croatian ST185, you have a GT4, not a Alltrac.
Alltrac is the US version.

The switch is in your radiator.
Right next to where the lower hose connects to it.

Thank you for the info. My ride is an alltrac i'm sure of it, not a gt4.
