Engine Overheating
You will find a coolant temperature gage on your
Oldsmobile’s instrument panel. See “Engine Coolant
Temperature Gage”
in the Index. You also have a low
coolant level light on your instrument panel. See “Low
Coolant Light” in the Index.
Overheated Engine Protection
Operating Mode
Should a low coolant condition exist, an overheat
protection mode which alternates firing groups of three
cylinders helps prevent engine damage. In this mode,
you will notice
a significant loss in power and engine
performance. The low coolant light may come on and
the temperature gage will indicate an overheat condition
exists. This emergency operating mode
allows your
vehicle to be driven to
a safe place in an emergency.
Towing
a trailer in the overheat protection mode should
be avoided.
I NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil
will be severely degraded. Repair
the cause of coolant loss and change the oil. See
“Engine Oil, When to Change” in the Index.
