2. Close the radiator drain valve.
3. Remove the engine coolant recovery reservoir and empty. Flush the reservoir with clean water, drain and reinstall.
IMPORTANT:
^
When refilling the engine coolant system, add three engine coolant supplement sealant pellets, GM P/N 3634621 or equivalent, and GM
approved new Ethylene Glycol Coolant DEX-COOL (TM).
^
If the engine cooling system is being refilled ONLY (no flush), a 50 percent DEX-COOL (TM) and 50 percent clean drinkable water mixture
should be used to fill the system. Fill the system until the level of the 50/50 mixture has reached the base of the radiator neck. Wait two
minutes and recheck the level of the engine coolant mixture, add a 50/50 DEX-COOL (TM)/drinkable water mixture as necessary to restore
the engine coolant mixture level to the base of the radiator neck.
4. Slowly fill the engine cooling system through the radiator neck using the following procedure:
4.1.
If the engine coolant system has been flushed first add 100 percent DEX-COOL (TM) in the amount listed in the graphic for the
appropriate engine application.
4.2.
Slowly add clean drinkable water to the system until the level of the engine coolant mixture has reached the base of the radiator neck.
4.3.
Wait for two minutes and recheck the level of the engine coolant mixture, add clean drinkable water if necessary to restore the engine
coolant mixture level to the base of the radiator neck.
5. Install the radiator cap making certain the arrows line up with the overflow tube.
6. Close all air bleeds. DO NOT over-torque the air bleed valve. The air bleed valve is made out of brass.
7. Add 0.65 liters (0.68) quarts) of a 50/50 mixture of DEX-COOL (TM) and clean drinkable water to the engine coolant recovery reservoir.
NOTICE: The Low Coolant warning/indicator lamp may come on after this procedure. If after operating the vehicle so that the engine heats up
and cools down three time, the Low Coolant warning/indicator lamp does not go out, or fails to come on at the ignition check, and the coolant is
above the full cold mark in the reservoir, refer to Low Coolant Warning/Indicator Lamp in Diagrams. If at any time the Temperature
warning/indicator lamp comes on, immediate action is required. Turn OFF the engine and allow the vehicle to cool. Do not remove the coolant
recovery reservoir cap at this time.
8. Inspect the coolant level after the engine heats up and cools down three times.
