Audi S1 Quattro Water Pump and Thermostat Housing Replaced.

Audi’s little S1 Quattro rocket ship has had a few problems when it comes to its cooling system, this water pump – thermostat housing has had seven re-designs since its original design due to failing water pumps and leaking joints.

Water pump – thermostat housing buried under everything!

To replace the water pump – thermostat housing on the Audi S1 Quattro is a fairly big job, we have to:

  • Drain the cooling system
  • Disconnect fuel lines and cooling hoses
  • Remove inlet manifold stabiliser bars
  • Remove the complete inlet manifold
  • Unbolt water pump drive cover
  • Remove the water pump and housing
  • Clean all surface faces and hose joints
  • Rebuild using genuine parts and all new seals
  • Refill with anti freeze and bleed cooling system
  • Road test and re-check
The leaking housing.

The water pump is driven off a small drive belt running from an internal engine shaft and should be replaced along with the water pump – thermostat housing.

New pump fitted, just got to rebuild now!

Once all the work was carried out and all final tests done the car was handed back to a very happy customer.
