Radiator Bottle Compatible with VW Golf MK1 and 2 - With Sensor Hole

The Radiator Bottle Compatible with VW Golf MK1 and 2 - With Sensor Hole is a practical replacement cooling-system component designed for compatible Volkswagen Golf Mk1 and Mk2 models. The radiator bottle, also known as a coolant expansion or recovery reservoir, provides an important storage point for engine coolant while accommodating normal changes in coolant volume as the engine heats up and cools down. Over time, the original plastic reservoir can become brittle, cracked, stained, or damaged through repeated exposure to engine heat, temperature changes, vibration, and general vehicle use. This replacement provides a convenient solution for replacing a deteriorated or leaking coolant bottle while retaining the required sensor-hole configuration for compatible vehicles. The bottle does not include the sensor, allowing the existing compatible sensor to be used where appropriate.

Replaces OEM part number 171121407F

Compatible with VW Golf MK1 and MK2: Designed for compatible Volkswagen Golf Mk1 and Mk2 applications, this radiator bottle provides a practical replacement for a damaged, cracked, leaking, or ageing coolant reservoir. It is intended for vehicles requiring the corresponding sensor-hole configuration and should be matched to the existing bottle, vehicle application, mounting points, and hose connections before installation.

With Sensor Hole for Compatible Systems: This radiator bottle features a sensor hole, making it suitable for compatible cooling systems that use a coolant-level sensor connection. The sensor opening allows the appropriate existing sensor to be fitted where compatible, helping maintain the intended configuration of the vehicle's cooling system. Sensor is not included with the radiator bottle.

Replaces OEM Part Number 171121407F: This replacement radiator bottle replaces OEM part number 171121407F, providing a useful reference when identifying the correct component. Comparing the OEM number with the original reservoir and checking the bottle's shape, mounting arrangement, hose connections, and sensor-hole position can help ensure the replacement is suitable for the intended vehicle.

Helps Maintain Proper Coolant Storage: The radiator bottle forms part of the engine cooling system by providing a reservoir for coolant and accommodating normal changes in coolant volume as engine temperatures rise and fall. A properly functioning reservoir helps keep coolant contained within the cooling system and supports the intended operation of the cooling circuit during normal vehicle use.

Ideal for Replacing Cracked or Leaking Reservoirs: Coolant reservoirs on older vehicles can deteriorate after years of exposure to engine heat and repeated temperature cycles. Plastic can become brittle and develop cracks, splits, or leaks that may result in coolant loss. Replacing the affected bottle provides a practical way to restore a secure coolant storage point and address deterioration of the original component.

Practical Solution for Maintenance and Restoration: This radiator bottle is suitable for vehicle owners, mechanics, workshops, restoration projects, and DIY maintenance where the existing coolant reservoir needs replacement. It can be used during cooling-system repairs, preventative maintenance, refurbishment, or restoration of compatible Golf Mk1 and Mk2 models. The sensor is not included, so the appropriate compatible sensor should be retained or sourced separately.

The Radiator Bottle Compatible with VW Golf MK1 and 2 - With Sensor Hole provides a practical replacement for damaged, cracked, leaking, or ageing coolant reservoirs, with OEM part number 171121407F and a sensor-hole configuration for compatible vehicles. It is a useful component for cooling-system repairs, maintenance, refurbishment, and restoration projects.
