Note: It is recommended to clean the wheel house in the oil cooler area before beginning with the work.
- Take off right front wheel
- Remove old oil cooler. First, disconnect oil hoses on oil cooler, counterholding with a second wrench. Catch escaping oil. Plug e.g. with tape or plastic plugs (no rags), oil hoses to prevent entry of dirt. Unscrew nut on upper rubber pad and lower nut. Remove oil cooler.
- Unscrew two-tone horns with holder. Remove both old holders and mount two-tone horns on new holder, Part No. 911.635.091.00; bolting long horn on short bracket. Bolt complete unit on fender support from below in such a manner that the two-tone horns are suspended vertically in front of the support.

- Place oil cooler without cover in holder in wheel house. Align upper holder with bore in oil cooler and tighten mounting nut for holder. Remove oil cooler again.
- Assemble oil cooler.

- Guide assembled oil cooler into wheel house. Mount on bottom holder with locknuts and washers.

- Mount oil cooler on upper holder (use large diameter washer 8). Tighten bottom nuts. Tighten oil hose coupling nuts, counterholding on cooler connections with a second wrench to avoid damage.
- Start engine and check oil level and connections for leaks. The regulator for the front oil cooler has to be open for this purpose – engine oil temperature above 80 degrees Celsius (176 degrees Fahrenheit)

Modified fenders beginning with 1985 models
A fender, on which the upper oil cooler holder is changed, is introduced beginning with 1985 models. The holder of this fender version is mounted laterally. For this reason holder, Part No. 930.207.927.00, is no longer required for installation of the new finned oil cooler. After depletion of stocks of old fenders the new version fender will also be valid for replacements in cars before 1985 models. In the repair sector require the use of rubber/metal pad, Part No. 930.207.239.00, and holder, Part No. 930.207.921.00 on the upper holder for installation of the oil cooler.
