Silicone Coolant Hose Kit for Citroën GS Birotor 1973-1975

Silicone Hoses for Citroën GS Birotor: Preserve an Exceptional Vehicle

The Citroën GS Birotor represents a unique chapter in French automotive history. With only 850 units produced between March 1974 and March 1975, this saloon equipped with the Wankel rotary Comotor twin-rotor engine remains one of the rarest vehicles ever marketed by Citroën. Unlike standard GS models fitted with air-cooled boxer engines, the Birotor features a liquid cooling system essential for operating its revolutionary 107-horsepower engine.

The Specific Cooling System of the Wankel Birotor Engine

The Comotor engine powering the GS Birotor requires a particularly efficient liquid cooling system. Temperatures generated by combustion in the trochoidal chambers demand constant coolant circulation. Original rubber hoses, after several decades, show inevitable degradation: hardening, cracking, loss of elasticity and risk of rupture. For such a rare vehicle, replacement with REDOX silicone hoses guarantees optimal reliability.

Why Choose REDOX Silicone for Your GS Birotor

REDOX hoses made from VMQ silicone offer exceptional mechanical properties compared to original rubber. Silicone perfectly resists extreme temperatures (from -50°C to +180°C), doesn't expand under pressure, maintains flexibility over time and resists chemical degradation from coolant. Our 3-ply construction with 4mm wall thickness guarantees superior mechanical strength against cooling system pressures.

Frequently Asked Questions about GS Birotor Hoses

Why must original hoses be replaced after so many years? Natural rubber naturally degrades over time, even if the vehicle is driven sparingly. After 40 to 50 years, hoses become rigid, crack and risk sudden rupture, causing catastrophic overheating of the rotary engine.

Is silicone compatible with the original cooling system? Yes, REDOX silicone hoses mount exactly in the same locations as original hoses, without any modification to the system. Supplied clamps ensure optimal and leak-free fitting.

Can I keep my current coolant? VMQ silicone is compatible with all types of coolants, whether glycol-based or organic. However, we recommend taking advantage of hose replacement to completely renew the coolant.

What is the lifespan of REDOX silicone hoses? REDOX silicone hoses carry a lifetime warranty. Under normal operating conditions, they maintain their mechanical properties for several decades without significant degradation.

Are coloured hoses as durable as black ones? Yes, blue and red colours use exactly the same VMQ silicone formulation as black. The colour is integrated throughout the material and represents only an aesthetic choice.

How to properly bleed the system after installation? After fitting new hoses, progressively fill the system with engine idling and expansion tank cap open. Monitor air bubble evacuation and top up the level until stabilisation.

Does REDOX maintain permanent stock for this rare vehicle? Yes, aware of the GS Birotor's rarity, REDOX maintains permanent stock to guarantee immediate availability. Order before 5pm for same-day dispatch.

Can I install these hoses myself or do I need a specialist? Installation requires no specialist tools. Anyone with basic mechanical skills can perform the replacement. Simply ensure proper system bleeding and correct clamp tightening.
