My 1990 E30 6cyl. has a problem. The heater guage goes to the top at the
hot position when driving for awhile. The interior has a anti-freeze smell,
and there is no heat. After a bit, the temp guage went down, and the heat
worked but the anti-freeze smell stays. Is it the heater core or thermostat?
What is involved in the replacement of the heater core if that is the issue?
I thank you for all replies.
