Bentley Continental GT GTC Flying Spur Lower Radiator Coolant Hose 3W0122101C – Quick Release Coupling Assembly

Bentley Lower Radiator Coolant Hose with Quick Release Coupling – 3W0122101C

Renew a critical section of the Bentley cooling circuit with this formed lower radiator coolant hose assembly, part number 3W0122101C. Designed for compatible Bentley Continental GT, Continental GTC and Flying Spur applications, it combines a reinforced coolant hose with the shaped end connection and quick-release coupling required for a secure factory-style installation.

Premium Materials & Build

The main hose body is made from heat-resistant reinforced automotive rubber formed to the original bend profile. Integrated molded connector sections, a metal retaining clamp and the quick-release coupling create a complete service part rather than a universal cut-to-length hose. The textile-reinforced outer section adds protection against abrasion and repeated thermal cycling.

What This Hose Does

The lower radiator hose carries coolant through the engine's main heat-rejection circuit. Because it operates through continuous heat cycles and system pressure, correct wall strength, connection geometry and sealing are essential.

• Restores a sealed lower radiator coolant path.
• Provides factory-style routing with molded bends.
• Quick-release coupling simplifies correct connection to the matching coolant fitting.
• Reinforced hose wall resists expansion and collapse during normal cooling-system operation.
• Excellent preventive replacement for aged, swollen or leaking original hoses.

Fitment

Compatible with Bentley models using OE reference 3W0122101C, including suitable Continental GT, Continental GTC and Flying Spur cooling-system configurations. Confirm by part number because Bentley used several different lower and upper coolant-hose layouts.

Replacement Guide

1. Work only with a completely cool engine.
2. Safely release residual coolant-system pressure and drain coolant below the lower-hose level.
3. Raise and support the vehicle correctly if underbody access is required.
4. Release the quick coupling and the opposite hose connection, collecting any remaining coolant.
5. Inspect the radiator and pipe connection surfaces; remove residue that could interfere with sealing.
6. Install the new 3W0122101C hose in the original orientation and lock the quick connector fully into place.
7. Secure all clamps and retainers, then refill with the correct coolant mixture.
8. Bleed trapped air, warm the engine and inspect both ends for leaks.

FAQ

What is a quick-release coolant coupling?
It is the molded locking connector at the hose end that attaches to the matching radiator or coolant-pipe fitting without a traditional worm-drive clamp.

What are common signs of a failing lower radiator hose?
Coolant drops, white or colored residue, swollen rubber, cracks, soft sections, overheating or a loose connector indicate replacement is due.

Can this hose be fitted without draining coolant?
The coolant level must be lowered below the connection point to keep the job controlled and prevent unnecessary coolant loss.

Does the hose need a special orientation?
Yes. Follow the molded bends and original routing so the hose sits naturally without twist or contact with nearby components.

How do I confirm the correct hose?
Match the OE reference 3W0122101C to the original hose or the vehicle parts catalogue before ordering.
