Action:

The manufacturers of the existing thermal switch (Kenlowe) have informed us that production has now been discontinued, therefore, these fitting instructions show how to fit the alternative 'Otter' switch now coming into production.

If a 'Kenlowe' switch is faulty and requires replacing, it must now be. replaced with the 'Otter' switch.

  1. Drain the radiator. Disconnect the battery.
  2. Using a hole-saw, cut a 27/32in. diameter hole in the front L/H corner of the top tank of the radiator (see illustration).
  3. Insert the grommet (Part No. A036 K 6027) into the hole, followed by the 'Otter' switch (Part No. A036 K 6026). NOTE WELL that a DRY joint must be used.
  4. Shorten the existing switch cable to reach the new switch location. Slide the terminal cover (Part No. A036 M 6414) onto the cable, attach the terminals (Part No. A036 M 6415) one to each lead, fit terminals to switch and slide cover into position.
  5. Remove faulty 'Kenlowe' switch and seal hole in radiator with plug (Part No. A036 K 0090).
  6. Refill cooling system. Re-connect the battery.
