CAUTION: Make sure the correct type 0-ring seals are installed on the A/C fittings.
6. Connect the heater water hoses to the heater core.
7. Connect the black vacuum supply hose to the A/C vacuum check valve in the engine compartment.
8. Fill the radiator to the correct level with the previously removed coolant or specified mixture of coolant and water
9. Connect the battery ground cable.
NOTE: On vehicles equipped with Electronic Engine Control (EEC), when the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the EEC processor relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.
