The fluid level may be checked by obs
erving the fluid level marks of the
recovery tank. The leve l should be between the FULL HOT and FULL COLD
mark when the system is at normal operat ing temperature. When the engine is
cold, the fluid level should be above the FULL COLD mark on the reservoir. At
normal operating temperatures, t he level should be between the ADD and the
FULL marks. Only add coolant to bring the level to the FULL mark.
CAUTION - Should it be necessary to remove the radiator cap, make sure that
the system has had time to cool, reducing t he internal pressure. If the system is
opened while the engine is st ill hot, scalding fluid and steam may be blown out
under pressure.
DRAINING AND REFILLING

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.

The cooling system should be drained, th
oroughly flushed and refilled at least
every 30,000 miles or 24 months. This operation should be done with the \
engine cold.
1. Drain the cooling system as de scribed earlier in this section.
2. Fill the cooling system with warm water and start the engine. Run the
engine until normal operating temperature is reached.
3. At this point, turn the engine o ff and again drain the cooling system.
4. Repeat this procedure until the flui d draining from the system is nearly
colorless.
5. Remove, empty and reinstall the coolant recovery reservoir assembly.
6. Fill the cooling system with a 50/50 mixture of ethylene glycol antifreeze,
as outlined in the prev ious procedure.
BRAKE MASTER CYLINDER
FLUID RECOMMENDATIONS
When adding or replacing the brake fluid, always use a top quality fluid, such as
Delco Supreme II or equivalent DOT-3 flui d. DO NOT allow the master cylinder
reservoir to remain open for long periods of time; brake fluid absorbs moisture
from the air, reducing it s effectiveness and causing corrosion in the lines.
Avoid spilling brake fluid on any of the vehicle's painted surfaces, wiring cables
or electrical connections. Brake fl uid will damage paint and electrical
connections. If any fluid is spilled on t he vehicle, flush with water to lessen
damage.
LEVEL CHECK

Fluid level should not be below MIN marking on reservoir.
