Stoney Racing R53-0001 Silicone Radiator Coolant Hose Kit – MINI Cooper S R52/R53

The Stoney Racing R53-0001 is a silicone replacement for the radiator and heater coolant hoses on the MINI Cooper S R52/R53, 2000–2006.

The kit replaces 15 hoses in the engine bay, covering the radiator, water pump, heater circuit, twin coolant pipes and expansion tank in one go. Each hose is built from 4-ply silicone with 3-ply polyester reinforcement, so it will not perish, swell or crack like ageing rubber hoses.

It is available in 7 colours and can be ordered with a full set of stainless worm-drive, spring or stainless T-bolt clamps, or without clamps if you plan to reuse your originals.

Clamp Options

Black Spring Clips are the type most manufacturers use. They give the most even clamping pressure and are generally the best choice for coolant hoses, although being mild steel they can show surface rust over time.

Stainless Worm-Drive clamps are fully stainless, so they will not rust, and they are easier to fit in tight spaces. A good choice if engine bay appearance matters.

Stainless T-Bolt clamps are the heaviest-duty option, ideal where maximum clamping force is wanted.

None lets you reuse your existing clamps. These hoses are slightly thicker than standard, so some original clamps may be too small.

Important Fitting Information

• Some coolants are not compatible with silicone hoses. Check your coolant before fitting.
• For the supercharged Cooper S only. The non-supercharged One and Cooper have their own kits.
• Use washing-up liquid or a silicone-based lubricant when fitting. Do not use oil-based lubricants.

What's in the Box?

• 15 × Stoney Racing reinforced silicone hoses in your chosen colour

Frequently Asked Questions

Will this fit a One or Cooper?

No. It is for the supercharged Cooper S R52/R53 only.

Does it fit automatic cars?

Stoney Racing lists this kit for manual cars. If you have an automatic, please contact us before ordering.

Which clamps should I choose?

Spring clips give the most even clamping force for coolant hoses. Stainless worm-drive clamps will not rust and are easier to fit. T-bolt clamps are the strongest option.

Can I reuse my original clamps?

Often, yes. However, these hoses are slightly thicker than the originals, so some factory clamps may be too small.

Is my coolant compatible?

Most coolants are fine, but some types are not compatible with silicone. Check your coolant before fitting.

What warranty do I get?

Stoney Racing silicone hoses carry a 3-year warranty.
