A rising temperature gauge in summer heat and dampness in the engine bay around the hose connections are classic signs that the cooling system on a late-build B18 122 is starting to wear out. Old rubber hoses harden and crack internally, while porous cores and leaking soldered joints in the radiator mean the coolant can no longer hold back the heat.

This category gathers cooling parts that fit the 122 with the B18 engine, model years 1967–68. The group includes the radiator, radiator hoses and hose clamps, the expansion tank and radiator cap, plus smaller sealing details such as O-rings, washers and sleeves. When going through the cooling system, the condition of the hoses, the tension of the clamps and the pressure valve in the radiator cap are typical checkpoints – a cap that doesn't hold the right pressure lowers the boiling point and can cause overheating even with a healthy radiator.
