[bmw] Re: [SIG@M535i] E28 Heater Core ??
Chris
Thanks for the advice. Is Tim M still on this list?
Part of my issue is keeping my daily driver on the road.
I was thinking I would try to purchase a used core and
a new hoses to and from the interior of the firewall. I've
heard horror stories of a pressure tested core being
put in then leaking.
I have found this response Off http://www.MyE28.com:

Perhaps Tim M would be able to tell these guys where they went
wrong. (-:

You basically have to take out the entire dash to get to the heater
core. It's
not that difficult, just that it takes a long time. And you're being
more of
an accountant than anything else (making sure you remember how many and
which
screws go with what piece).
You DO NOT have to remove the AC evaporator (thanks to Tim M who did
this
job). You can finagle the heater core by removing the top half of the
heater
box out. The AC evaporator has enough play to be able to remove the
heater
core out.
Plan for a full days work (morning, afternoon, and evening).
