Rally Cars Need Heaters Too

We could have just wiped the dust of the heater box a bolted back in place but we are glad we took it apart as we found the heater core had been weeping or leaking. Besides, all the seals needed replacing and it was full of leaves inside.

We had also broken off a tab from the blower while removing it from the heater box so that needed to be glued back together.

The heater box consists of two halves held together by spring clips. It didn't take long to split it.

The leaky heater core and its replacement. These seem to have been used in every Audi, VW and Porsche made in the 80s so finding one was quite easy.

We broke a clip off the heater core lid but have already found a replacement on eBay. We'll pop that on after the dry build.

New seals and into the car with it and the cover we got from a fellow Quattro enthusiast.

It's nice to bolt things to the car. We get all warm and fuzzy inside, plus we'll be warm inside the car too.

We also took the opportunity to refinish our helper springs for the coilovers. Even though these have never been used most of the powder coating had already deteriorated. We decided to try Plasti-dip rather than re powder coating as this is way more flexible and will not crack. We will see how well that works one day in the future.
