GAT 3496 Radiator Hose

GAT 3496 Radiator Hose: Precision Cooling for Classic European Engines

The GAT 3496 Radiator Hose is a high‑performance cooling component engineered to meet the exacting standards of classic Peugeot, Citroën, and Talbot models. Designed with advanced EPDM (ethylene‑propylene‑diene rubber) technology, this hose delivers superior durability, flexibility, and resistance to heat, pressure, and chemical degradation.

Key Technical Specifications

• Model Number: 3496
• Material: EPDM rubber with reinforced steel braid for structural integrity.
• Diameter: 38 mm (1.5 in.) inner diameter, ensuring optimal coolant flow.
• Length Options: Standard 365 mm (14.4 in.) curved length; extended 415 mm (16.3 in.) variants available for specific chassis configurations.
• Pressure Rating: Up to 10 bar (145 psi) – suitable for high‑pressure cooling systems.
• Temperature Range: -40 °C to +120 °C, accommodating extreme operating conditions.
• Compatibility: Fits original equipment on Peugeot J5, Citroën C25, Talbot Express (various model years), and related chassis platforms.

Design Features That Set It Apart

The GAT 3496 hose incorporates several engineering innovations that make it a preferred choice for restoration enthusiasts and professional mechanics alike:

• Curved Geometry: The 365 mm curved profile matches the original routing on many classic models, reducing stress points and preventing kinks.
• Reinforced Steel Braid: Encased within the EPDM layer, the braid resists expansion under pressure while maintaining flexibility.
• Dual‑Seal Construction: Dual O‑ring seals at both ends provide leak‑proof connections to radiator and engine block fittings.
• Heat‑Resistant Coating: A protective outer layer resists UV exposure, oxidation, and thermal cycling, extending service life.

Installation Guidelines

Proper installation is critical to achieving reliable cooling performance. Follow these steps for a flawless fit:

1. Preparation: Drain the coolant system completely and allow all components to cool.
2. Remove Old Hose: Carefully detach the existing hose from radiator and engine block, noting the orientation of the O‑rings.
3. Inspect Fittings: Check for wear or corrosion on the mating surfaces; clean with a solvent if necessary.
4. Apply Sealant (Optional): For added security, apply a thin layer of high‑temperature silicone sealant to the O‑ring grooves.
5. Attach Hose: Slide the new GAT 3496 hose onto the fittings, ensuring the O‑rings seat correctly. Tighten clamps or bolts to manufacturer specifications.
6. Re‑fill Coolant: Reintroduce coolant, purge air pockets by running the engine with the heater on, and check for leaks.

Performance Benefits

When installed correctly, the GAT 3496 hose delivers:

• Consistent Coolant Flow: Maintains optimal pressure throughout the cooling loop, preventing overheating.
• Reduced Noise: The flexible EPDM construction minimizes vibration and humming associated with rigid hoses.
• Long‑Term Reliability: Resistance to cracking, swelling, and chemical attack ensures a lifespan that exceeds many aftermarket alternatives.

Maintenance Tips

Even the most robust hose benefits from routine checks. Inspect for:

• Visible cracks or bulges along the length.
• Signs of wear on O‑rings or fittings.
• Any leaks at connection points during operation.

Replace the hose if any of these issues are observed to maintain system integrity.
