Genuine Coolant Expansion Tank Cap - Rover 200/400/600/25/45/ZR/ZS/F/TF PCD100160

This item is always carried in stock for same-day dispatch. 

Losing coolant without a trace? The first thing to try is a new expansion tank cap. They often fail, meaning they don't hold pressure and allow coolant to boil off.

Cheap caps don't tend to last - this is a genuine item as fitted at the factory, and will give you years of good service.

Fits all K4 K Series petrol and L Series diesel variants.
