Stoney Racing DEF200-0007 Silicone Radiator Coolant Hose Kit – Land Rover Defender 200TDI RHD 1989–1991

The Stoney Racing DEF200-0007 is a silicone replacement for the main radiator and heater coolant hoses on the Land Rover Defender 200TDI RHD 1989–1991, 1989–1991.

The kit replaces all 7 coolant hoses in the engine bay, from the top and bottom radiator hoses to the heater, bypass and expansion tank hoses. 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.
• Fits only early models with downward-facing heater box connections (up to chassis HA700655).
• Use washing-up liquid to lubricate the hoses when fitting. Never use WD40 or any oil-based lubricant.
• Always dilute coolant with de-ionised water, never tap water, and never mix coolant types.

What's in the Box?

• 7 × Stoney Racing reinforced silicone hoses in your chosen colour
• Full clamp set in your chosen style (if selected)

Frequently Asked Questions

How do I know if I have the early or late 200TDI?

The early kit fits up to chassis HA700655, where the heater box connections face downwards. From HA700656 the connections are horizontal and you need the '91–'94 kit.

Why are some colours on pre-order?

Stoney Racing makes some colour and clamp combinations to order. These are marked as pre-order and dispatched in around 3–6 weeks.

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 are, but some coolants (particularly some OAT types containing 2-EHA) can damage silicone. Read the Important Fitting Notes linked on this page, which list compatible coolants.

What warranty do I get?

Stoney Racing silicone hoses carry a 3-year warranty.
