Silicone Coolant Hose CITROËN C25 2.5D (1981-1994)

Definition and Technical Specifications

The REDOX silicone hose for CITROËN C25 2.5D is an essential component of the engine cooling system. Specifically designed for commercial vehicles equipped with the 2.5L diesel engine (codes U25/651 and U25/661), this high-performance hose advantageously replaces the original rubber hoses.

Manufactured from premium VMQ silicone, this hose features a reinforced 3-ply construction with a 4mm wall thickness. This architecture guarantees exceptional resistance to pressure and temperature variations inherent to the operation of the 4-cylinder engine with 2499 cm³ displacement developing 75 horsepower.

The operating temperature range extends from -50°C to +180°C, ensuring optimal performance in all climatic conditions and usage scenarios. VMQ silicone offers superior resistance to thermal degradation, ozone, and chemical agents present in modern coolants.

Applications and Compatible Models

This hose fits perfectly to all CITROËN C25 vehicles equipped with the 2.5D engine produced between 1981 and 1994, in all their variants:

• Panel Van: standard versions, high roof, short and long wheelbase
• Minibus: 9-seater configurations and more
• Chassis-Cab: preparations for specific bodywork
• Dropside: goods transport versions
• 4x4: all-wheel drive off-road versions

The CITROËN C25 2.5D, twin vehicle of the PEUGEOT J5, equipped numerous professional fleets in France and across Europe. Its naturally aspirated 2.5-liter diesel engine developed 150 Nm of torque at 2000 rpm, particularly appreciated for commercial applications and motorhome conversions.

Main Technical Characteristics

• Material: VMQ Silicone (Methyl Vinyl Polysiloxane)
• Construction: 3-ply reinforced
• Wall thickness: 4mm
• Temperature resistance: -50°C to +180°C continuous
• Pressure resistance: optimized for automotive cooling circuit
• Available colours: Blue, Black, Red (to choose)
• Included accessories: High-quality hose clamps
• Warranty: Lifetime on silicone material
• Compatibility: Direct replacement without modification

The advantage of VMQ silicone over original EPDM rubber lies in its superior dimensional stability. Where rubber hoses tend to harden, crack and lose their elasticity with time and thermal cycles, silicone retains its mechanical properties over decades of use.

The supplied clamps are precisely sized to ensure optimal retention without risk of leakage, while allowing easy disassembly during future interventions.

FAQ - Frequently Asked Questions

Q1: Is this hose compatible with my 1987 CITROËN C25 2.5D? Yes, this hose fits all CITROËN C25 vehicles equipped with the 2.5D engine produced between 1981 and 1994, regardless of the year. It directly replaces the original rubber hose.

Q2: Why choose a silicone hose rather than rubber? VMQ silicone offers significantly superior durability. Unlike rubber which hardens and cracks over time, silicone retains its elasticity and resistance to extreme temperatures for decades, thereby reducing breakdown risks and maintenance costs.

Q3: Are hose clamps included in the delivery? Yes, high-quality hose clamps adapted to the hose diameters are systematically included with your order.

Q4: What delivery time for an order placed today? Any order placed before 5pm is dispatched the same day. GLS delivery occurs within 24 to 48 working hours in France and within 48 to 72 hours for the rest of Europe.

Q5: Does the lifetime warranty cover all types of use? The REDOX lifetime warranty covers material and manufacturing defects under normal usage conditions. It does not cover damage resulting from incorrect installation, accident or inappropriate use.

Q6: Can I install this hose myself? Installation is straightforward and requires only basic tools. Simply partially drain the cooling circuit, remove the old hose, install the new REDOX hose and tighten the clamps. Ensure to bleed the system after refilling.

Q7: Does this hose also fit the PEUGEOT J5 2.5D? As the PEUGEOT J5 2.5D is the technical twin of the CITROËN C25, many parts are interchangeable. However, we recommend checking the specific OEM reference of your J5 or contacting us for confirmation.

Q8: What is the difference between blue, black and red colours? The difference is purely aesthetic. All three colours offer exactly the same performance and technical characteristics. The choice depends on your visual preferences or the harmony sought in the engine bay.
