In about a month I am going to swap the motor and everything out to my 1st gen. In the mean time I am tired of the low coolant light coming on. Can someone tell me if I can unplug the sensor and use a resistor or something to bypass it for now?

 

well, will the light stay lit if it is unplugged?

 

nope, it goes out

 

does "low coolant" trigger anything in the pcm? does it change any settings?

 

no the light will go off if you unplug it,mine was on, so I took the sensor out and cleaned it( had grime in it, or something) I just wiped it clean , and put it back in and pluged it back up,and the light did not come back on for a few weeks, I guess I need to flush the system , the sensor get's dirty and the light comes on, but I have'nt flushed it yet, mine is still unpluged for now

 

nope, it only triggers the light on the dash. you're fine, go out and unplug it

 

I never understand this question. Why would you do this? You can blow a head gasket, or ruin your engine, or both if the coolant happens to really be low one day.

How can it bother you that much, it' not like it's a blinding light, or a lound alarm. I would say just ignore it, but that could end up with the same result. Anyways , to each his own, but again you should try cleaning it, which works for a number of people, or get a new one. I don't think they cost that much. I have seen lt1 engine need a rebuild, and have to have the heads surfaced for ignoring that light, much less disconecting it.

 

I am VERY meticulous on checking fluid levels... the lightis just an annoyance. and considering everything will be coming out in a few weeks anyway, it's a simple job to unplug it for now..won't have to drain coolant, won't have to remove the battery and maybe the alternator, heater hoses etc just to get my hands in there and pull it out...
