Product Details

This high-quality reinforced silicone hose allows for simple removal of the failure-prone after run coolant pump found on B5 Audi S4 and C5 Audi A6/Allroad models equipped with the 2.7T engine. Simply remove your auxiliary water pump and hoses, and replace them with this silicone hose. New hose clamps are included!

The 2.7T engine as supplied in the B5 S4 and C5 S6/A6/Allroad was plagued with a low quality plastic after run coolant pump, they tend to leak and sometime even explode.  To complicate matters, the pump is located underneath the intake manifold and can take hours to change.  High HP cars don't need it if you're sensible about cooling down the car, in cars that need it its a great idea to re-locate the pump to an easier to reach location.

Constructed from high quality multi-ply reinforced silicone, includes two hose clamps.
