O.E. Style Austin Healey Silicone Bottom Hose | CapeSport
Additional information:
Description:

Cloth-wrapped triple-ply silicone bottom radiator hose for the Austin Healey 100 BN1 and BN2. Using an original BN1/BN2 sample supplied by Roger Moment, the precise curve was recreated to guide coolant from the radiator to the water pump on the standard BN1-BN2 layout, then built in hard-wearing silicone with a black cloth outer wrap for an original-style appearance.

What’s in it for your Healey

  • Flow integrity – reinforced walls help prevent collapse under suction.
  • Chemically stable – ozone resistant; suitable for classic green coolant and 2-EHA-free long-life coolants.
  • High-temperature endurance – rated to 180 °C.
  • Resists ageing – silicone helps reduce cracking and hardening associated with long service life.
  • Original-style finish – cloth wrap matches OE-style texture for a tidy presentation.
  • Fit checked from an original – profile based on a BN1/BN2 sample supplied by Roger Moment.

Fitting notes and limitations

  • Do not over-tighten clamps on silicone. Tighten until sealed, then recheck after a full heat cycle.
  • Inspect radiator outlet and water pump inlet for corrosion or pitting that can prevent sealing.
  • Confirm the hose run is not kinked and clears nearby components before final tightening.

FAQs

Is this the correct bottom hose for BN1 and BN2?

Yes. It is shaped from an original BN1/BN2 sample and suits the standard BN1-BN2 bottom hose routing. BN4-BJ8 uses a different bottom hose.

Why does a bottom hose need reinforcement?

Bottom hoses can see suction loads. Reinforced walls help the hose keep its shape under demand, reducing the risk of collapse in use.

Which coolants can be used?

The hose material is suitable for classic green coolant and 2-EHA-free long-life coolants. Always follow coolant manufacturer mixing guidance.

Which hose clip style should be used?

Jubilee clips offer the widest adjustment range. O.E. double wire and pin and strip styles are often chosen for a more period look, provided sizing is correct and clamps are not over-tightened.

Do silicone hoses need rechecking after fitting?

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