Engine Overheating - Buick 2000 Century Owner's Manual

With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-
or car carrier equipment. Additional ramping may be
-
required for car carrier equipment. Don't have your
vehicle towed on the drive wheels, unless you must.
If the vehicle must be towed on the drive wheels,
do not tow the vehicle more than 500 cumulative miles
(800 km) or exceed 50 mph (80 km/h). If these
limitations must be exceeded, then the drive wheels
have to be supported on a dolly.
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See "Roadside
Assistance" in the Index.

Engine Overheating

You will find a coolant temperature gage and a hot
engine warning light on your instrument panel cluster.
See "Engine Coolant Temperature Gage" and "Engine
Coolant Temperature Warning Light" in the Index.
You also have a LOW COOLANT warning light on
your instrument panel cluster. See "Low Coolant
Warning Light" in the Index.
Overheated Engine Protection
Operating Mode
-
lift
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation.
Should an overheated engine condition exist, an
overheat protection mode which alternates firing groups
of 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. Towing a trailer in the overheat protection mode
should be avoided.
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" in the Index.
