Installing Bracket For Oil-Water Heat Exchanger

Installing bracket for oil-water heat exchanger

Information

Component overview

Note: The illustrations apply to the Cayenne Turbo (M48/50).

















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.





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.





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





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-lb. +2 ft-lb.





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








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.





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-lb.

Subsequent work

1. Fasten lock mount.





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





3. Tighten the front apron on the underside.





4. Fit engine guard.





5. Fill and bleed the cooling system.
6. Check oil level and adjust.
