Genuine Febi Coolant Expansion Tank Cap - Rover 200/400/600/800/25/45/ZR/ZS/F/TF PCD100160 / PCD000040 inc MG ZS180

In stock.
Genuine Febi part - the best cap we've found available, as used on all of our fleet! 

This part is applicable to both PCD100160 and PCD000040 - this cap has the slightly higher opening pressure of the Rover 45 V6 and MG ZS180, but is backwards-compatible with PCD100160 as used on other models too. 

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 tried-and-tested item we've used extensively on our own fleet for many years. 
We believe this is the best PCD100160 cap on the market! 
Don't believe us? We helped create a video showing the differences between the various offerings; you can watch it here.

Fits all K4 K Series petrol, KV6 petrol and L Series diesel variants along with KV6 variants of the Rover 800.
