When building a YC Zetec it is important to use the correct water pump housing. The YC housing uses a tear dropped water inlet instead of the standard round inlet.





The YC inlet housing also has a larger inlet tube that when used with the YC water pump and housing increases coolant flow by a 50%. This was done to address the overheating issues the original Montune WRC Zetec encountered.





The housing was also milled to remove unnecessary material to save weight on the original rally car.
