Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, how much coolant have you added?
what engine do you have? there are 4 different ones , If unknown? I would need 8th digit of the Vin, thanks
please send full vin #. I fully understand the question, I have to do some checking on things so please bear with me. It takes a few minutes
Thanks, ***** ***** have the 3.5 litre engine. By default, the AC will be turned off when a problem is detected and computer sets a code, We do not have the code so,, with guage on 0? I am thinking the coolant temp sensor has failed, If it does? it will nor signal the computer, you will get zero reading on dash, AC will turn off automatically till the problem is fixed, I know low on coolant but gugae would have gone up if temp was running high so,, you either have a bad sensor or it is possibel the PCM is failing and not reading the sensor but kind of doubt it. We do not have the code nor do we have a scanner hooked up viewing live data so,, working off symptoms etc? you have a bad sensor, Now... you can try removing BOTH battery cables from the battery, Hold the ends together best you can for minimum 90 seconds, generally this will clear the computer , the light and it may? all start working again, If not? then? the sensor is likely bad, Now,, its either on back of the head, back of engine as shown in first picture OR it is on back side of block as second picture and #5. I think its on top at back of engine screwed into the right cylinder head as picture # ***** It will have a orange/Black wire and a yellow wire going to it.
