Will it fit my Mercedes B Class?
Belt-driven on TDIs (do it with the cambelt). Some petrols are chain or electric pumps — confirm type for your engine code.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Mercedes B Class water pump needs replacing
- Overheating / temp gauge climbing
- Coolant leak (often weep hole)
- Whining bearing noise
- Low coolant warnings
Fitting it yourself
If cambelt-driven, only sensible to do alongside the belt. Refill and bleed the cooling system after.
