Coolant connection for the VW Golf 5 and Golf 6 – OE part number 1K0 121 087 H.
This useful replacement part helps to avoid unnecessary installation problems. The coolant connection with original part number 1K0 121 087 H is a known wear item on many VW Golf 5 and Golf 6 models. Due to the age of these vehicles and the plastic materials used at the time, the original connection can become brittle and may easily break or start leaking, particularly during removal or work in the engine bay.
When fitting the HG Motorsport HFI intake system, this area sometimes has to be partially removed. To avoid unnecessary delays, coolant loss or consequential damage, the coolant connection is available as a suitable replacement part.
