⚡ At a Glance
- • Build Quality: Aluminium alloy construction resists high temperatures and corrosion, improving service life and reliability
- • Best for: Owners of VW MQB cars with 1.8L and 2.0L TFSI/TSI engines needing a direct coolant pipe replacement
- • Not ideal for: Vehicles outside the VW MQB platform or engines other than 1.8L/2.0L TFSI/TSI
Direct replacement listed as OEM 06K121143 for VW MQB applications, used between water pump and thermostat to prevent coolant leakage and overheating. Overall size 42.5 x 40 x 25 mm, nozzle diameter 9.8 mm, washer diameter 24.5 mm and circular hole diameter 6.5 mm.
Reliable, leak-resistant joins - with washer and precise dimensions
Designed to connect the cooling channel between the water pump and thermostat; includes a washer sized 24.5 mm to sit against the mating surface and a circular hole of 6.5 mm for secure seating. Overall and nozzle dimensions help align the coolant path accurately.
Tight sealing at the thermostat junction reduces the chance of coolant leaks and subsequent overheating when fitted to matching MQB engines.
Improved longevity - thanks to aluminium alloy construction
Aluminium alloy replaces original plastic pipework, offering higher resistance to underbonnet temperatures and corrosion. The metal construction limits thermal degradation that commonly affects plastic connectors.
Greater durability means fewer replacements over time, which reduces the need for repeat repairs in heat-stressed cooling systems.
Straightforward fit in tight engine bays - with compact OEM-sized dimensions
Compact overall size of 42.5 x 40 x 25 mm and a nozzle diameter of 9.8 mm match the space constraints typical of MQB engine layouts. OEM reference 06K121143 helps confirm correct fit before installation.
Simplifies DIY or garage replacement when the accessory number matches, avoiding lengthy modification or rerouting.
