Heater box material

Postby jhh » Mon Feb 12, 2018 3:34 pm

Hi,
does anyone know what kind of material is the heater box made of? Specifically the upper section which holds the heater core. I have 1979 spider which has black plastic type box and it is cracked and I'm wondering if it is made of something nasty and should be taken care of. Not fun to blow for example asbestos or any other fibers inside cabin...

Well it is plastic thats for sure.
It could have the nasty stuff in it. You can get a tester at a local Home Depot or Lowe's.

not sure of the material its made of but I repaired mine by gluing the crack with MEK. It melts the existing plastic material to itself.

Replace it. Some are bakelite and break pretty easily especially after 40+ years.

$65 well spent.

It bothered me so much that I sent a sample piece to examination and they confirmed that it doesn't contain asbestos.
I haven't seen the report so I don't know exactly what those fibers are they mixed in the bakelite, but atleast not asbestos

It would be highly unlikely for a coolant based heater box to contain asbestos since if the coolant got hot enough to ignite in the heater box you'd likely be long dead already.

On an older Volkswagen with its gas fired heater or heat exchanger on the head or exhaust system then yes there could be asbestos in it since those areas are at combustible temperatures. The gas fired heaters in those mounted right underneath the fuel tank always gave me the Willies.

Yes I knew it was unlikely but when you add bakelite + fibers in it + some heat + 1970s + paranoid owner, I wanted to be sure. But now I know and wanted to share the information.

Most likely wood fiber in a hot water heater box. Yes under the hood and in electrical components it could have been asbestos.

There is a greater chance though (please don't freak out) that the handles on your pots and pans and knobs on your stove and oven are made of Bakelite using Asbestos fibers. If you smoke a vintage pipe made after 1910 there is a good chance that the stem is made with Bakelite using Asbestos fibers too along with most older electric home appliances many of which also had sheets of asbestos inside them including toasters and hair dryers. Some brake linings are still Asbestos Bakelite too.
