Grand Caravan V6-3.3L Flex Fuel (2008)
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Service and
Repair/Procedures/Refrigerant Oil Level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as
designed and can cause serious A/C compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be
added to the refrigerant system See: Service and Repair/Procedures/Refrigerant Oil Level.
NOTE: Replacement of the refrigerant line O-ring seals is required anytime an underbody refrigerant line is disconnected. Failure to replace
the rubber O-ring seals may result in a refrigerant system leak.
1. Position the underbody lines (1) underneath the vehicle body and install the six retaining screws (2 and 3). Tighten the screws securely.
CAUTION: Use care not to damage the ABS wire lead or the brake line when installing the brake line bracket.
2. Install the rear brake line bracket, brake line and ABS wire lead onto the rear frame rail.
3. Install the right rear shock mount onto the rear frame rail and remove the jack stand from under the rear axle.
4. Reposition the exhaust system and connect the four rubber exhaust hanger isolators.
5. Connect the front heater hoses (4) to the underbody heater lines (3) and install the hose clamps securely.
6. Remove the tape or plugs from all the opened refrigerant line fittings and the rear expansion valve ports.
7. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto all the underbody refrigerant line fittings. Use only the specified
O-rings as they are made of a special material for the R-134a refrigerant system. Use only refrigerant oil of the type recommended for the A/C
compressor in the vehicle.
8. Connect the front A/C suction line (6) and front A/C liquid line (5) to the underbody refrigerant lines (1 and 2). Tighten the fitting nuts to 23 Nm
(17 ft. lbs.).
