on during engine starting, your
vehicle does have the Computer Command
Control system.)

2 . Move
the transmission shill lever to "P"(Park) or "N"(Neutral) ("P"
preferred). A starter . safety device is designed to keep the starter from
operating if the shift
lever is in .any drive position . (If you need to re-start
the engine while the vehicle is moving, move the shift lever to "N ." )

follow the instructions which apply to your engine . (The Engine Code is the
8th digit on the
VIN plate at the lower left side of your windshield . See
. "SpeCifications" .Section 7 oUhis manual for more details.) "~" ...

If the engine does not start or starts, but fails to run, repeat this
procedure
.

Downloaded from www.Manualslib.com manuals search engine 4. Close the drain valve. Install the block drain plugs, if removed. Add water
until the system is
filled and run the engine until the upper radiator hose is
hot
again.
5. Repeat steps 3 and 4 several times until the drained liquid is nearly colorless.
6. Drain the system, then close the radiator drain valve tightly. Install block
drain plugs, if removed.
7. Disconnect all hoses from the coolant recovery tank. Remove the recovery
tank
and pour out any fluid. Scrub and clean the inside of the recovery
tank with soap and water. Flush it well with clean water, then drain it.
Reinstall the recovery tank and hoses.
8. Add enough water and ethylene glycol antifreeze (meeting GM
Specification 1899-M) to provide the required cooling, freezing and
c()rrosion protection, Use a solution that is at least 50 percent antifreeze out no mOre than 70 percent antifreeze. Fill the radiator to the base of the
filler neck
and fill the coolant recovery tank to the "Full Hot" mark. Put the
recovery tank cap back on.
9. Run the engine, with the radiator cap removed, until the upper radiator
hose is hot.
10. With the engine idling, add coolant to the radiator until it reaches the
bottom of the filler neck. Install the radiator cap, making sure the arrows on the cap line up with the overflow tube.
iI is the owner's responsibility to,
'. -Main)!!!n cooling system freeze protection at -3rC (-34'F) to ensure protection against corrosion and loss of coolant from boiling. (A 50/50
mixture of water and ethylene glycol antifreeze will provide freeze
protection to -37'C or -34'F.) You should do this even if you don't
expect freezing temperatures.
• Add ethylene glycol base' antifreeze that meets GM Specification 1899-M
when antifreeze haS to be added because of coolant loss or for more
protection against freezing at temperatures lower than -37'C (-34'F).
NOTICE: Do "otute methanol-base antifreeze, Of alcohol,or plain water alone, in your vehicle at any time. They will boil at a lower point than that at which the "TEMP"
light (or temperature gage) will warn of overheating,. and they do not provide proper protection against cOrrosion.
Radiator Pressure Cap
The radiator cap, a 105 kPa (15 psi) pressure type, must be installed tightly,
otherwise coolant may be lost and damage to engine may result from
overheating. Radiator pressure
caps should be checked periodically for proper
operation. If replacement is required, an AC cap is recommended.
Thermostat
The engine coolant temperature is controlled by a thermostat. It stops coolant
flow
through the radiator until a preset temperature is reached. This thermostat
is installed in the engine
coolant outlet on the engine block. The same thermostat is used in both winter and summer. When a replacement is needed, AC"Delco parts are recommended.
