I've finally got fed-up with an intermittant fault, and want to change the coolant temp sensor for the ECU (93 WRX).
I've managed to locate the sensor, which is on the top of the engine, under the inlet manifold.
Can I change the sensor without having to drain the coolant (was thinking of syphoning off coolant from the header tank)
The sensor is typically awkward to get to...any hints on how to remove it?
Cheers

Afternoon to you mate - I changed the coolant temp sensor on MY93 WRX last year. You are quite correct in your assumption that it is a b1tch to do (have a scar to prove it). I didn't drain any coolant from the system at all and unfortunately found out the hard way...... removed the old temp sensor and glug glug out poured the coolant couldn't stop the stuff and couldn't get the replacement sensor in place due to the fluid pumping out of the hole and the sensor being in a tricky place.
If you are not going to syphon off the coolant then be prepared to have to put some coolant back in. Hope this helps...btw what is the intermitent problem you are talking about ??
Good luck
