Fitting notes and limitations

FAQs

Where does this hose fit on the car?

It connects the heater circuit to the cylinder head tap on BN1-BN2 cars using the standard heater hose routing.

Does this fit BN4 to BJ8?

No. BN4-BJ8 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 look.

Should the clips be rechecked after fitting?

Yes. Recheck clip tension after the first full heat cycle.
