Fitting notes and limitations

  • Do not over-tighten clamps on silicone. Tighten until sealed, then recheck after a full heat cycle.

  • Confirm the hose run clears sharp edges and rubbing points before final tightening.

FAQs

Where does this hose fit on the car?

It is used on BN4-BJ8 cars for the heater-to-water-pipe connection on the standard heater circuit routing.

Does this fit BN1 or BN2?

No. BN1-BN2 uses different heater hose routing for this connection.

Which clips should be used?

Use 1/2 inch heater hose clips. Jubilee offers wider adjustment, while O.E. double wire is often chosen for a more original appearance.

Should the clips be rechecked after fitting?

Yes. Recheck clamp tension after the first full heat cycle, especially on silicone hoses.
