cooling system - Is it Safe to Drive With Low Engine ...

· If you can't see any obvious signs of leaks, or steam coming from anywhere if you run the engine, a likely cause is a cracked cylinder head gasket, which is letting the coolant into the cylinders and out of the tail pipe as steam. That could soon cause a lot more damage than the hassle carrying a water container in the car to top up the radiator.

It sounds like in your case, the coolant sensor is either incorrect, or you have two failed sensors - it happens, although not all that often. Plugged in, the sensor is sending a signal ...

And when it is condensed, it will mix with oil ...

Do engines absolutely need an O2 sensor to function ...

They'd use mechanical springs, grub screw adjustments and vacuum pipes to keep the fuelling in check. I should probably add that the reason for the O2 sensor was to protect the cat from getting drowned in unburned fuel which can happen occasionally in a traditional ...

SOLVED: Engine temp sensor bypass or test - Fixya

· Om most vehicles, you can't. The coolant temperature sensor sends a variable signal to the ECM based on coolant temp, and that value is used by the ECM in the computation of the fuel mix (rich/lean) to the injectors. Without it, the vehicle will run poorly, if at all, and will set the Check Engine Light. There MAY be a separate coolant sensor that simple controls the radiator fan. This one could be bypassed, but that comes with great risk of engine …

I found this site and the information worked for me. I needed a new sensor …
