Additional information:
Description:

Hand-made in the UK from Kevlar-reinforced rubber. This bottom radiator hose suits the standard Austin Healey BN4 to BJ8 cooling layout where a bottom hose without heater take-off is required, and is intended as a direct replacement when renewing ageing hoses.

Key Benefits

  • UK made – produced from Kevlar-reinforced rubber (K suffix).
  • Chosen for durability – designed to cope better with temperature fluctuations than standard hoses.
  • Correct application – formed for BN4-BJ8 bottom hose routing on the standard layout.

Will this fit my car?

Fits: Austin Healey BN4, BN6, BN7, BT7, BJ7 and BJ8 where the cooling layout uses a bottom hose without heater take-off.

Excludes: BN1 and BN2 bottom hose applications. Not suitable where a bottom hose with heater take-off is required. Not suitable for modified cooling conversions that change routing or connection sizes.

What’s Included

  • 1 × Bottom radiator hose (Kevlar-reinforced rubber)

Which hose clips can be used?

Choose the clamp style that suits the engine bay and service preference:

Pin & strip clips are typically chosen for earlier BN1-BN6 period presentation. If used, confirm clamp sizing and suitability for the joint.

Also Available

Fitting notes and limitations

  • Confirm the car uses the bottom hose configuration without a heater take-off before ordering.
  • Inspect radiator and engine spigots for corrosion or pitting that can prevent sealing.
  • Ensure the hose is fully seated, tighten clips evenly, then recheck after the first full heat cycle.

FAQs

Is this the correct bottom hose for BN4 to BJ8?

Yes, provided the cooling layout uses a bottom hose without heater take-off. If a heater take-off is needed, use the bottom hose with heater pipe variant.

What does Kevlar-reinforced rubber change in practice?

The reinforced rubber is chosen to cope better with temperature fluctuations than standard hoses, supporting longer service life in regular use.

Which hose clip type should be used?

Jubilee clips offer the widest adjustment range. O.E. double wire clips are often chosen for a more original appearance, provided sizing is correct.

Should clips be rechecked after fitting?

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