dried out foam in air conditioning system

I think from my 328 / 308 experience - the foam my actually be from the heater boxes - it gets old and just starts to flake off... so cold air passes through same tubes ... I used a shop vac to suck out as much as I could from those boxes which in the 328 are up front under the spare tire surround... Not sure where / how in the Mondial. I think what you lose is insulation for heat & cooling...

 

I can say on the 328 it can be repaired. But the repair is costly because that heater box is not made to come apart. It has to be disassembled, the foam removed, the box reassembled and then it needs to be insulated.

 

I think if I remember right - the boxes are riveted together... for some reason I remember the 308 you could actually take the top off... and when you look in it was a lot of disintegrated foam. it did not bother me until one time the foam flew right into my eyes as I was driving ... then you realize it is a problem. best of luck!

 

Follow you air intake ducts to the "square box", not sure where it's located on the Mondial, in the 308 there's two.

This box DOES come apart, somehow, as inside is a foam air filter.
The best way forward is to replace it with a brass screen media, as it's there for bugs, water and gravel from the road.

I really don't think any of those are going to travel very far in the system and enter the cockpit.
Maybe someone reading can post the Mondial Parts Diagram, but the 4" x 4" x 4" box is pretty prominent under the front bonnet, in our cars.
HTH

 

I think this is right, it is riveted. So not a difficult job but costly.

 

yes. if I remember right its a pretty cheap looking set up. its like the cork tape on the AC system... if you buy from Ferrari its like $50 a ft... if you buy from a hobby shop ( HO RR track bed ... an entire box is like $20 with about 50'......

 

I believe it’s the foam between the black vent on the dash and the air box. Mine fell apart when I looked at it. Carefully pry the vent from the dash and replace the foam with a suitable

 

Interesting thread.
I would like to know the end result. Removing and replacing the foam or a substitute, can the box be separated, short cuts.
Wishing the OP best of luck.

 

PM me.
I may have some of the Mondial Center Vent Foam Rebuilding kits available.
