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.
