The Gates 3843 Radiator Hose is a high‑performance cooling system component designed to replace worn or damaged hoses in a wide range of automotive models, particularly those from the Peugeot and Citroën families. This hose delivers reliable heat transfer, durability, and resistance to the harsh conditions found inside an engine bay.

Key Features

• Material Composition: Made from EPDM (ethylene‑propylene‑diene rubber) which offers excellent chemical resistance, flexibility at low temperatures, and high temperature tolerance up to 200 °C.
• Construction: Dual‑layer design with an inner layer of reinforced synthetic fiber for strength and an outer layer of protective EPDM coating to guard against abrasion and UV exposure.
• Dimensions: Standard length of 530 mm (21 inches) with a diameter of 32 mm, suitable for both upper and lower radiator connections in most models.
• Pressure Rating: Rated to withstand up to 10 bar (145 psi), ensuring safe operation under high‑pressure coolant systems.
• Temperature Range: Operates effectively from –40 °C to +200 °C, accommodating extreme climates and engine temperatures.
• Compatibility: Designed for a broad range of vehicles including Peugeot 306, Citroën ZX, XM, Berlingo, Xsara, and many others. The hose is available in both upper and lower variants to match OEM specifications.

Applications & Vehicle Compatibility

The Gates 3843 Radiator Hose fits a variety of models across multiple years:

• Peugeot 306 (1995‑2001) – both upper and lower hoses for petrol and diesel variants.
• Citroën ZX, XM, Berlingo, Xsara (1992‑2000) – compatible with 1.6L to 2.0L engines.
• Peugeot Partner, Citroën C4, and other MPV/van platforms sharing the same cooling architecture.
• Specific model codes such as 1351N1, 1351W1, 1351X9, 95667382, 1351K4, 1351V5 are supported for both upper and lower hoses.

When selecting a hose, always verify the exact model code of your vehicle’s cooling system to ensure optimal fitment. The Gates 3843 series is engineered to match OEM specifications, providing seamless integration without the need for additional adapters or modifications.

Installation Guide

1. Preparation: Drain the coolant system completely and allow the engine to cool. Remove any old hoses carefully to avoid damage to fittings.
2. Inspection: Check the hose clamps, fittings, and radiator for corrosion or wear before installation.
3. Fitment: Slide the new Gates 3843 hose onto the upper or lower fitting. Ensure that the hose is seated fully within the clamp to prevent leaks.
4. Securing: Tighten the hose clamps evenly, using a torque wrench if available, to avoid over‑tightening which can damage the EPDM material.
5. Reassembly: Refill the cooling system with the appropriate coolant mixture. Bleed air from the system according to your vehicle’s service manual.
6. Testing: Start the engine and monitor for leaks or abnormal pressure readings. Verify that the temperature gauge remains within normal operating range.

Maintenance Tips

• Inspect hoses annually for signs of cracking, bulging, or hardening.
• Avoid exposing hoses to direct sunlight for extended periods; use protective covers if necessary.
• Replace any hose that shows wear before it fails to prevent coolant leaks and overheating.
