Engineered for strength and reliability, the Land Rover Defender 300TDI Silicone Coolant Hose Kit (Right-Hand Drive) replaces critical OEM rubber hoses with reinforced, high-performance silicone alternatives. Designed to withstand the extreme demands of towing, overlanding, and daily driving, this kit ensures consistent coolant flow and superior resistance to heat, pressure, and vibration. Multi-ply silicone construction prevents common failures such as cracking, swelling, and splitting, making it a long-term upgrade for classic Defender 300TDI models. Operating across a wide temperature range from -50°C to +220°C (with peaks up to +250°C), the hoses maintain flexibility and strength even under harsh conditions. With a precision-moulded OEM+ finish, the kit enhances both the performance and appearance of the cooling system.

Key Features & Benefits:

Direct Fit: Designed specifically for Land Rover Defender 300TDI (RHD) with no modifications required.
Reinforced Silicone: Multi-ply construction resists cracking, splitting, and heat degradation.
Enhanced Cooling: Smooth internal bore ensures stable coolant flow under load.
Off-Road Ready: Built for rugged environments, ideal for overland and heavy-duty applications.
Long-Term Reliability: Prevents premature hose failure common with ageing rubber parts.
OEM+ Appearance: Clean, professional finish for an upgraded engine bay look.

Each kit is supplied complete with 304 stainless steel hose clips, sized precisely for each hose to provide a secure, corrosion-resistant seal. The combination of reinforced silicone hoses and stainless steel clamps ensures long-lasting performance in both on-road and off-road conditions. This makes the kit an essential preventative upgrade, reducing the risk of cooling failures during demanding use.

Ideal for restoration projects, performance tuning, or preventative maintenance, the Land Rover Defender 300TDI silicone coolant hose kit ensures dependable cooling system operation and peace of mind in all driving environments—from city roads to remote trails. By upgrading to silicone, Defender owners gain durability, thermal stability, and enhanced reliability, keeping their vehicle ready for any adventure.

Frequently Asked Questions.

Answers to the questions we’re asked most about sizing, fitment and performance.

Still can't find your answer?

What is it, and what does it fit?

A complete set of silicone hoses for this Land Rover, made to the correct bores, lengths and bends so each piece drops straight in. Check the model, engine and year range on this page against your vehicle before ordering.

How do I make sure it fits my car?

Match on model, engine and year or facelift, because hoses often change mid-generation. The most certain method is the OE part number on the part you are removing. If you cannot find one, send us photos of the old hose with a tape measure alongside, or your registration, and we will confirm.

Why replace the original?

Original rubber and plastic parts perish, harden and crack with age and heat cycling. Silicone does not perish and handles far higher temperatures, so on a part that is awkward to reach, fitting silicone once is considerably cheaper than doing the job twice.

Does it come with clips?

Some of our listings offer clips as an option at checkout - check the options on this page. Where they are not included, we stock stainless worm drive clips and T-bolt clamps in every matching size. Always renew clips with a hose: old ones lose tension and corrode where you cannot see.

Is fitting a kit a big job?

It varies by vehicle - a coolant hose kit means draining and refilling the system and bleeding the air out properly, which is the part people underestimate. Allow more time than you think for access to the hoses behind the engine, and have fresh coolant and clips ready.

What if my exact model is not listed?

We manufacture bespoke silicone hose to order and make one-off parts regularly. Send us the old part, a sketch with dimensions, or an OE number, plus what flows through it and the temperature it sees, and we will quote. Small quantities are welcome.
