Installing bracket for oil-water heat exchanger
1. Replace both O-rings in the flange. To do this, carefully lever out the O-rings with a non-abrasive implement (plastic wedge) and replace them with new ones.
2. Replace the O-rings on the oil transfer flange. To do this, lever off the O-rings with a non-abrasive implement (plastic wedge) and replace them with new ones.

Allen Key In Bracket:

ATTENTION: Danger from oil-water heat exchanger!
^ If the compensating element is not screwed in, the bracket can be braced and will break during operation as a result.
--> Before installing the bracket, screw the compensating element in completely.

3. Screw in length-compensating element. To do this, insert an Allen key through the screw hole into the bracket and turn the key anti-clockwise until the compensating element touches the bracket.
4. Apply a thin coat of engine oil to the two transfer flanges and position the bracket on the engine. Then push the bracket hard against the engine until the fastening screws can be put into place.

Sleeve And Fastening Screws For The Bracket:

5. The sleeve -1- is screwed in. Position the two fastening screws -arrows- and tighten until hand-tight.

Allen Key In Bracket:

6. Adjust compensating element. To do this, insert an Allen key -picture- through the screw hole into the bracket and turn the key clockwise until the compensating element touches the engine. Tightening torque 1.5 ft. lbs. +2 ft. lbs..

Bracket Fastening Screws:

All Three Fastening Screws:

7. Fit the upper fastening screw -arrow-. Insert the screw through the compensating element and tighten it. Tightening torque 17 ft. lbs.. Then tighten the 2 other fastening screws. Tightening torque 17 ft. lbs..

Pushing Coolant Lines Onto Connecting Piece:

8. Fit coolant lines from oil-water heat exchanger. Push both coolant lines onto the socket piece and fit the spring-band clamps using the spring-band clamp pliers.

Union Nuts For Oil Return Lines:

Note: The following step must only be performed for the M48/50 (V8 Turbo) engine.

9. Fit oil return lines for turbochargers. Insert the lines into the connections and align them. Then screw in the union nuts by hand and tighten them. Tightening torque 26 ft. lbs..

1. Fasten lock mount.

Support Plate Fastening Screws:

2. Fit the support plate under the radiator. To do this, tighten the 4 fastening screws. Tightening torque 17 ft. lbs..

Front Apron Fastening Screws:

3. Tighten the front apron on the underside.

Engine Guard:

4. Fit engine guard.

Cooling System:

5. Fill and bleed the cooling system.
