okay i have a 6 hour drive i need to take tomorrow. my check engine light has been intermittent for the past couple months thanks to faulty o2 sensors so i figured since i have a long drive tomorrow i should change them. i changed the passenger side primary o2 sensors in about 15 minutes with a bosch universal that some fellow members suggested to me. i attempted to change the driver side too but eventually said eff it cuz it was getting late and theres other shiz i gotta do... now as i turn the engine on it starts up fine. check engine light is gone. 20 or so seconds pass and my temp alarm beeps and flashes at me?!? i checked my wiring, i checked my plugs. the car runs fine just that temp thing is flashing at me... WTF i really need help quick if anyone can help me...is my car safe to drive for 6 hours? i didnt let it get up to temp at all cuz i just shut it off. turned the car back on and 20 seconds later the same ****...

 

do you have a obd 2 scanner? if you had that you could hook it up and run the car and just follow the data on the scanner and see how hot the car actually gets...otherwise i dont know what to tell ya feller.. if it comes on in like 2 minutes or less its probably wrong cause your car wont warm up that fast..but.. anyhow..

 

HAAA, so last night bout 11 oclock right before i drifted to sleep i basically stood out of bed in a sudden rush and said "you ******* idiot!" yea so i forgot to connect the coolant level sensor underneath the expansion tank.... problem fixed!

 

This was very helpful...thanks for the long ago follow up.

 

I have had a few really BRILLIANT moments just like that myself.
