Plumbing!

Once the radiator is fitted the plumbing can be started. Two stainless steel pipes are supplied that run under the front wheel arches and through the driver and passenger sills. The fuel tanks are also installed into the sills so the water pipes are insulated with pipe lagging, one to protect them and two to stop them rattling in the stainless steel sills. Once the pipes are “Teased” into the sills and through holes into the engine bay, the rubber hoses can be fitted that connect the pipes to the radiator. Make sure that you cover the open ends (engine bay) to ensure not debris goes into the pipes during the build. When using an electric water pump, you may need to modify the return pipe to create a heater bypass.

The heater pipes run down the drivers (right) side of the inner sill and the air conditioning pipes run down the passenger (left) side of the car. Whilst fitting the air conditioning pipes it is wise to also fit the clutch hydraulic pipe at the same time. (This is for the Audi Gearbox, if using ZF gearbox I think the pipe goes down the right-hand side of the car).
