What does a mechanic do to service an engine?
I'm driving a borrowed 1994 Cadillac Deville. A notice showed up on the instrument
panel today that said, "Service Engine Soon".
I took the car in for an oil change recently. The information on the readout on the dash
says there's 70% oil left before the next oil change.
Another notice showed up last week that said something about checking the coolant.
A neighbor filled it up with coolant. Also, how do I know if this car is over-heating? I
don't see a temperature gauge on the dash.
