The aux coolant pump sounds like a good idea for a Vanagon. At normal idle I
get much less heat because of poor coolant circulation. I know this is a
characteristic of the Vanagon cooling system.

I assume what you are talking about is a electric pump. Who made /where did
you purchase the pump you installed on the BMW? Does in mount directly in
line with or in parallel with the coolant lines?

Hi David,

1) Make sure the heater hoses are not pinched or restricted with tight
plastic ties.
2) Make sure the hot coolant control valve opens fully with the sliding
lever.
3) I installed an aux coolant pump used on Swedish BMW 3 series cars and
I use it at slow RPM. I live in NY State and I have plenty of heat.
