FLUIDS AND LUBRICANTS

FLUID DISPOSAL
Used fluids such as engine
oil, transmission fluid, antifreeze and brake fluid are
hazardous wastes and must be disposed of properly. Befo re draining any fluids,
consult with your local authorities; in many areas waste oil, etc. is being
accepted as a part of recycling programs. A number of service stations and auto
parts stores are also accepti ng waste fluids for recycling.
Be sure of the recycling cent er's policies before draining any fluids, as many will
not accept different fluids that have been mixed together.
FUEL RECOMMENDATIONS
The engine is designed to operate on unleaded gasoline ONLY and is essential
for the proper operation of the emissi on control system. The use of unleaded
fuel will reduce spark plug fouling, exhaust system corrosion and engine oil
deterioration.
In most parts of the United States, f uel with an octane rating of 87 should be
used; in high altitude areas, fuel wit h an octane rating as low as 85 may be
used.
In some areas, fuel consisting of a blen d of alcohol may be used; this blend of
gasoline and alcohol is known as gaso hol. When using gasohol, never use
blends exceeding 10% ethanol (e thyl or grain alcohol) or 5% methanol (methyl
or wood alcohol).
The use of fuel with excessive amounts of alcohol may jeopardize the new car
and emission control system warranties.

Fill the cooling system wit
h a 50/50 mixture of water and Ethylene Glycol
antifreeze. Freezing protection should be appropriate for temperatures of -34°F
(-37°C). When filling the coolant system, add two cooling system sealer pellets
(GM part no. 3634621 or equivalent).
9. Firmly set the parking brake. Run t he engine with the radiator cap OFF,
until normal operating tem perature is reached.
CAUTION - Under some conditions, ethylene glycol is flammable. To avoid
being burned when adding engine coolant, do not spill it on the exhaust system
or on hot engine parts.
10. With the engine idlin g, add engine coolant to t he radiator until the level
reaches the bottom of t he radiator fill neck. Install the cap assembly.
When installing the cap, make sure t hat the arrows on the cap line up
with the overflow tube.
Never add cold water to an overheated engine.
11. Add coolant to the recovery tank, as necessary.
12. After filling the radiator and recovery tank, run the engine until it reaches
normal operating temperature, to ma ke sure that the thermostat has
opened and all the air is bled from the system.
