1991 Chevy G20 My Van does not produce much heat. If I turn the fan up i get cool air yet if on low or off i can feel heat just at the vent. If i am driving a while i seem to get adequate warm air but...


The heater core may be coroded and pluged up. Its common on older cars. f the cooling system was drained recently and refilled its possible there os air in the system which will block the flow through the heater core. You should also check the valve ,usually on heater hoses to make sure it is opening and closing properly when you turn the temp up.

Be vary careful I think that it may have a reverse flow water pump. You can install the belt two different ways. Both will work but the wrong way will shorten you engine life a whole lot. Try your local library for a book on you car.

How do i replace heater core


I believe on a 1987 chevy van the heater core should be under the black plastic cover on the firewall on the left hand side as you are standing in front of the van.
I believe you can also get to it under the passenger side dash.
It is NOT fun. Unless you are a seasoned mechanic, I would not attempt it.
Otherwise stop by your local auto center, and get a HAYNES manual, they will be able to show how to.
