Silicone Coolant Hose N°1 REDOX — Alpine GTA V6 Turbo 1985-1991

Product Definition and Technical Specifications

The REDOX coolant hose No.1 (Ref. 1222) is a multilayer VMQ silicone hose engineered specifically as a direct replacement for the original cooling circuit hose on the Alpine GTA V6 Turbo. Built from polyester-reinforced VMQ silicone, it delivers continuous temperature resistance from -50°C to +180°C — significantly superior to the original rubber hoses of the era, which were only rated to -30°C to +120°C.

The multilayer construction provides exceptional dimensional stability under pressure, preventing the deformation and collapse commonly seen with aged rubber hoses. The smooth inner bore promotes optimal coolant flow, contributing to the thermal stability of the famously heat-sensitive PRV 2.5L Turbo engine, whether in daily driving, hillclimb events, or historic track days.

Verified technical specifications:

• Material: Multilayer VMQ silicone, polyester-reinforced
• Continuous temperature rating: -50°C to +180°C
• Available colours: Alpine Blue, Black, Red
• Fitment: Direct replacement, no modifications required — 100% plug-and-play
• REDOX reference: 1222

Applications and Compatible Models

This hose is developed exclusively for the Alpine GTA V6 Turbo, produced from 1985 to 1991, fitted with the PRV (Peugeot-Renault-Volvo) 2.5L Turbocharged engine producing 200 hp.

Confirmed compatibility:

• Alpine GTA V6 Turbo Phase 1 (1985-1987) — Garrett T3 turbocharger
• Alpine GTA V6 Turbo Phase 2 (1987-1990) — enlarged air-to-air intercooler
• Alpine GTA V6 Turbo Mille Miles (1989) — limited edition
• Alpine GTA V6 Turbo final series (1990-1991) — ABS equipped
• Left-hand drive (continental Europe) and right-hand drive (UK market)

Original rubber hoses fitted to these vehicles are now over 30 years old. Hardening, micro-cracking and porosity are the inevitable result of this ageing — placing the PRV engine, known for its sensitivity to thermal fluctuations, at genuine risk of overheating and coolant leaks. Replacing them with a REDOX silicone hose is the definitive long-term solution for GTA owners and collectors.

OEM References for Original Hoses

According to documented manufacturer data, the GTA V6 Turbo cooling circuit hoses belong to the Alpine/Renault reference family 6001009186, covering the cooling system of both the D501 variant (without air conditioning) and the D502 variant (with air conditioning).

Note: As most original Alpine parts are now out of production and extremely difficult to source, REDOX hose Ref. 1222 provides a direct fit replacement without any adaptation.
