1998 CHEVROLET EXPRESS ECU

Downloaded from www.Manualslib.com manuals search engine Whenever a wheel, wheel bolt or wheel nut is replaced
on
a dual wheel setup, check the wheel nut torque after
100, 1,000 and 6,000 miles ( 160, 1 600 and 10 000 km)
of driving. For proper torque, see “Wheel Nut Torque’’
in the Index.
See “Changing
a Flat Tire” in the Index for more
information.
Used Replacement Wheels
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
how
far it’s been driven. It could fail suddenly
and cause an accident. If you have to replace
a
wheel, use a new GM original equipment wheel.
NOTICE:
Use tire chains only where legal and only when you
must. Use chains that are the proper size for your
tires. Install them on the tires of the rear axle.
Tighten them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you can
hear the chains contacting your vehicle, stop
and retighten them.
If the contact continues,
slow down until it stops. Driving too fast
or
spinning the wheels with chains on will
damage your vehicle.
