Heater blower padding!
« on: November 10, 2014, 19:44:39 »
Hello Guys,
I removed the complete heater system from my car. 1966 230Sl
Just want to have a tip from you on the Blower and distributor box. I could see when I put apart that there were some padding in some places to avoid rattling. Could you guys please guide me where exactly there are places where i should use the padding(felt or rubber) on these items. See the parts before and after.
Thank you in advance for any input.

The technical manual linked me to your photos. I remove the radio of my 280SL to get access to the cables and, until seeing your photos, I thought the Behr device behind the radio was the heater core. I cannot imagine how you removed it without taking apart your entire car. Regards from New Orleans, BigLou

We used a grey foam material and used the outline of the heater box openings as a template. This was not an exotic type of material, as the environment is not all that nasty. It is a pain in the butt (and various other body joints and pieces) to do this. I have attached a photo of the heater box with the foam glued in place.

The process for removal and refit is quite good, but also quite a labor. My friend and I did this on his car and on mine. I highly recommend taking the seats and steering wheel out (not a big deal at all) it gives you much more maneuvering room. The 280 SL is a bit more difficult, as the dash is now a one piece set-up. You have to work through the radio cut out.

And yes, this is the very epitome of "we have this great little heater core, we should build a car around it...."
