Why It Matters
The Wasserboxer cooling system is long and complicated, and it is very sensitive to air pockets and small leaks. Original hoses go hard, crack at the ends or swell soft, and a weeping hose at the coolant distributor lets air in and coolant out. The usual signs are a sweet coolant smell, drips under the engine, a falling expansion tank level, and an engine that runs hot or loses heat. Overheating a Wasserboxer risks head gasket and head damage, so worn hoses are worth replacing before they fail.
Installation Notes
- Drain enough coolant to lower the level below the hose before removal.
- Clean the pipe ends and check them for corrosion or cracks.
- Use new hose clamps and position them clear of the hose bead.
- Refill with the correct coolant mix and bleed the system carefully using the bleed screws, following your workshop manual, until all air is out.
- Recheck the level and look for leaks after the engine has cooled.
