Hi Listees,

I am doing a bit of tuneing etc. on my '82 air cooled vanagon and have
a couple of questions for ya'll.

Does anyone have a technique for cleaning installed heat exchangers?
Mine don't seem to be too dirty and they heat really well but there is
a bit of an oily smell when the engine gets really warm (currently no
oil leaks above/into heat exchangers).  I have planned to remove
enough ducting to be able to spray the air passage with a steam
cleaner, is this an awful idea?

Does anyone have experience with the Bus Depot replacement
thermostats?  I am having trouble determining if my current
thermostats 6mm of expansion/contraction is enough so I thought I'd
just replace it but I have heard that most new thermostats are very
proned to fail.

Thanks all,

Jonathan Poole
