Has anyone tried putting the stock coolant temp switch (the one on the bottom of the driver side of the stock road)? I am installing a new Koyo radiator but I'm noticing that the bung that it screws into is recessed such that it doesn't seal. If I can't use the stock sensor, how is this going to effect the car itself and it's drivability?

Thanks in advance

 

That particular sensor matters only in terms of operation of the air injection (smog) system. I posted details about it in a comment here (referred to as "sensor #2) if you want more detail on what it does, specifically.

 

So after reading through that and the FSM, it seems like I can just leave it out since I won't be using the car in temps under 60F. Do I have that right? Thanks for the reply, really helped understand the vast systems the rats nests holds haha.

 

Yes, that's correct - driveability-wise you won't have any issues.

If you really wanted to be a stickler, put a jumper in the connector so that it always indicates "above ~60F" to the ECU (which will ignore that sensor completely once the engine is >158F anyways).

 

Thank you for the help, I can't wait to get the car back on the road finally.
