5-Piece REDOX Silicone Coolant Hose Kit for Citroën DS3 Racing 202hp 207hp (2010-2015) EP6DTS Engine

What is the REDOX Silicone Hose Kit for DS3 Racing?

This engine cooling system comprises 5 VMQ silicone hoses specifically engineered for the Citroën DS3 Racing equipped with the 1.6-litre EP6DTS turbo engine. Developed to replace OEM rubber hoses, these REDOX high-performance hoses guarantee maximum reliability under extreme motorsport conditions.

Each hose is manufactured from 3-ply VMQ silicone with 4mm wall thickness, offering exceptional temperature resistance between -50°C and +180°C. VMQ silicone exhibits superior elasticity compared to natural rubber, eliminating risks of expansion, cracking, and hose bursting under pressure.

Main Technical Specifications

The kit includes 5 coolant hoses covering the entire water circuit of the DS3 Racing engine. Material: 3-layer VMQ silicone. Wall thickness: 4mm. Temperature range: -50°C to +180°C. Maximum operating pressure: 3 bar. Stainless steel clamps included. Direct fitment replacing OEM hoses. Compatibility: bolt-on installation without modifications. Available colours: blue, black, red.

Verified Applications and Compatibility

This kit is specifically developed for the Citroën DS3 Racing produced between 2010 and 2015, equipped with the EP6DTS turbo engine. This 4-cylinder 1598cc engine produces 202 horsepower (2010-2011 version) or 207 horsepower (2011-2015 version), with maximum torque of 275 Nm. The EP6DTS engine belongs to the Prince family jointly developed by PSA and BMW.

The DS3 Racing, developed by Citroën Racing, represents the high-performance version of the standard DS3. Its production was limited to 2000 units per year. The EP6DTS engine also powers other PSA Group sports models like the Peugeot 207 GTi and 308 GT, sharing the same cooling components.

Benefits of Permanent Stock and Express Delivery

REDOX maintains permanent stock of DS3 Racing silicone hoses in French warehouses. Orders placed before 5PM are dispatched same day via GLS courier, with guaranteed delivery within 24 to 48 hours throughout Europe. This immediate availability enables tuners and motorsport enthusiasts to receive their parts quickly, unlike typical ordering delays of several weeks with other suppliers.

Each kit is carefully packaged and supplied with all necessary mounting clamps. The REDOX lifetime warranty covers all manufacturing defects and demonstrates confidence in the exceptional durability of the VMQ silicone used.

Why Replace OEM Hoses with Silicone?

The rubber hoses fitted as standard on the DS3 Racing are manufactured from EPDM natural rubber. This economical material enables mass production at low cost but exhibits limited mechanical properties. Under the effect of repeated thermal cycles and turbo cooling circuit pressure, the rubber gradually degrades. The material hardens, loses elasticity, and develops micro-cracks that evolve into visible fractures.

The VMQ silicone used by REDOX offers superior chemical resistance to modern coolants, dimensional stability even under high pressure, flexibility maintained across the entire temperature range, and lifespan exceeding 10 to 15 years. On a turbo engine developing 275 Nm torque, cooling circuit reliability becomes critical to avoid destructive overheating.

Installation and Fitting

Installing the 5-hose kit requires basic mechanical skills and standard tools. Estimated installation time: 2 hours. Tools needed: set of ring and open-end spanners 8 to 13mm, screwdrivers, coolant drain pan, funnel. Procedure: drain cooling circuit when engine cold, remove OEM rubber hoses by loosening clamps, clean metal pipes, fit new REDOX silicone hoses with supplied clamps, refill circuit with fresh coolant, bleed system, check for leaks with warm engine.

Fitting is completed without vehicle modifications. REDOX hose dimensions correspond exactly to OEM specifications, guaranteeing perfect assembly on all EP6DTS engine pipes.

FAQ - Frequently Asked Questions

Do REDOX hoses fit all DS3 models? No, this specific kit is designed exclusively for the DS3 Racing equipped with the EP6DTS engine of 202hp or 207hp produced between 2010 and 2015. For other DS3 versions (VTi, standard THP), different kits exist. Verify the engine code on your registration document (5FD or 5FF for EP6DTS).

What is the difference between silicone and OEM hoses? OEM EPDM rubber hoses have a limited lifespan of 5 to 7 years and degrade under heat. REDOX VMQ silicone hoses withstand more extreme temperatures (-50°C to +180°C versus -30°C to +120°C), retain elasticity over time, don't crack and benefit from lifetime warranty.

Can these hoses be self-installed? Yes, installation is accessible to any amateur mechanic with basic tools. Fitting time is approximately 2 hours. Detailed instructions are provided with the kit. It's recommended to take advantage of replacement to install quality fresh coolant.

Do the hoses provide a performance gain? Silicone hoses maintain constant internal diameter under pressure, unlike rubber which can expand. This optimises coolant circulation and contributes to better engine thermal stability, particularly beneficial on track or during spirited driving.

How long until I receive my order? DS3 Racing kits are in permanent stock. Any order placed before 5PM is dispatched same day. GLS delivery occurs within 24 to 48 hours across the UK and Europe. A tracking number is provided immediately upon dispatch.

Are mounting clamps supplied? Yes, the kit includes all stainless steel clamps required for fitting. These professional clamps guarantee optimal tightening and perfect sealing throughout the hoses' lifespan.

Which colour should I choose for my engine? Colour choice is purely aesthetic and has no impact on performance or durability. Available colours are blue, black and red. Blue and red are popular in motorsport preparation for their visibility in the engine bay. Black offers a more discreet OEM-like appearance.

Does the lifetime warranty really cover the vehicle's entire lifespan? Yes, REDOX provides lifetime warranty on its silicone hoses against any manufacturing defect. This warranty demonstrates the exceptional quality of VMQ silicone used and the manufacturing process. Under normal use, silicone hoses can last over 15 years without degradation.
