huh? is it in the hose? lol... i dont think a sensor is gonna cause you to overheat... maybe get a new thermostat, clean the cooling system, new water pump?

That sounds like an aftermarket coolant temp sensor, for a gauge. Does not have anything to do with the ECU's coolant temp sensor or the factory gauge sensor, both of which are in the upper water neck.

There is an inline sensor on SOHC cars that triggers the electric fan. Not found on DOHCs unless it was swapped or rigged in for some reason.

this man speaks the truth.

ive fitted these onto a handful of sr swapped cars as a nice trigger for a cooling fan relay.
