Engine Cooling System: Removal & Installation Dodge Charger VI

INSTALLATION

1. Install the lower supply line to the coolant recovery container (3)
2. Position the coolant recovery container.
3. Install mounting screws (2). Tighten to 10 N.m (89 in. lbs.).
4. Install the coolant recovery return tube (3).
5. Fill cooling system. Refer to «STANDARD PROCEDURE»(ref-481395-S18502976792012062200000) .
6. Install coolant recovery container pressure cap (1).

Scheme 13

All cooling systems are equipped with a pressure cap on the radiator. This cap releases pressure at some point within a range of 110-138 kPa (16-20 psi). The pressure relief point (in pounds) is engraved on top of the cap (3).

The cooling system will operate at pressures slightly above atmospheric pressure. This results in a higher coolant boiling point allowing increased radiator cooling capacity. The cap contains a spring-loaded pressure relief valve (4). This valve opens when system pressure reaches the release range of 110-138 kPa (16-20 psi).

A rubber gasket (2) seals the radiator filler neck. This is done to maintain vacuum during coolant cool-down and to prevent leakage when system is under pressure.

REMOVAL

1. Remove upper radiator closure panels
2. Using Release Tool (special tool #8875A, Disconnect, Transmission Cooler Line), remove transmission cooler lines from transmission cooler. Refer to «STANDARD PROCEDURE»(ref-481395-S18502976792012062200000) .
3. Raise vehicle on hoist.
4. Remove front transmission cooler lines from the thermal bypass valve block.
5. Remove rear transmission cooler lines from the thermal bypass valve block
6. Remove the transmission cooler lines from the transmission.

1. Install rear transmission cooler lines at transmission. Tighten fittings to 20 N.m (18 ft. lbs.).
2. Install rear transmission cooler lines to thermal bypass valve. Tighten fittings to 20 N.m (18 ft. lbs.).
3. Install front transmission cooler lines to thermal bypass valve. Tighten fittings to 20 N.m (18 ft. lbs.).
4. Install front transmission cooler lines into transmission cooler. Refer to «STANDARD PROCEDURE»(ref-481395-S18502976792012062200000) .
5. Lower vehicle.
6. Check transmission fluid level. Refer to «FLUID AND FILTER, STANDARD PROCEDURE»(ref-481422-S28284294982012062200000) .

Scheme 14

The transmission thermal bypass valve is mounted on LH side of the engine at the A/C compressor.

1. Raise and support vehicle.
2. Remove front transmission cooler lines from the thermal bypass valve block (2).
3. Remove rear transmission cooler lines from the thermal bypass valve block (2).
4. Remove thermal bypass valve block (2).

1. Position thermal bypass valve. Install mounting bolt. Tighten mounting bolt to: 2.7L/5.7L/6.1L engine 50 N.m (37 ft. lbs.), 3.0L/3.5L engine 26 N.m (19 ft.lbs.).
2. Install rear transmission cooler lines to thermal bypass valve. Tighten fittings to 20 N.m (18 ft. lbs.).
3. Install front transmission cooler lines to thermal bypass valve. Tighten fittings to 20 N.m (18 ft. lbs.).
