Hi Jeff,

Your post went to my junk box.  I’ll re post below hoping others will see it.

My heater core in the rear started to smell in 2013 and I didn’t find any coolant.  I changed it and the valve going into it.  The Van cafe valve is very strong.  That did it.  No more smell and a very useful rear heater.
I used the bus Depot core at the time.

This is one of the jobs I’ve gotten good at having done it on  my first vanagon as well.

Pretty sure my rear heater core is leaking but I see no evidence of it. When I turn the fan on I smell it. I’ve taken the cover off but see no leakage. What am I missing?

Don’t tell me to remove it. I’m in the great white north and it’s essential!

Thanks
Jeff
