the 96 astro van I just picked up has a heat problem.
The thermostat is opening and closing like it should.
the air seems to be putting out cold air.(not really warm engough out side to tell this correctly)
I also noticed the when the stat does open the temps on the engine drop to below 200 degrees.
I went looking for the heater controll valve with no luck.

It does look like some body might have put a new heater core in this van.

research on line so far says this valve is behind the washer over flow bottles in front of the heater core with a vacuum line running to it.
So far i have not located any thing like this yet.
this weekend i plan on pulling the doghouse cover and give the engine a good looking over along with replacing the coolant.
Right now my Early has more heat than this van has.

Thanks in advance for any help in this matter.

Catfish, I was at these forums all ready.
I really can not locate this heater controll valve they are talking about.

The water hoses on this Astro run from the block directly into the heater core it's self.

I have a feeling somebody has been in here eliminating things.

I also read that they have eliminated this valve and got better heat.

This vacuum line is also missing along with a vacuum ball.

I have to agree with you Joe. Somebody must have removed all those controls. Ack!

That pic looks like the vacuum supply plugged directly into the check valve with no can.
I would suggest making a new canister from an old V8 juice can. (get it? coulda had a V8? laugh )

Do the heater hoses get hot to the touch near the heater core? If so, you probably have a air bubble in your heater core. With the way the hoses come in low on the core, it is not hard to get one while swapping the core out.

Unk,honestly I have not checked that yet.
There was also an air bubble mentioned on the Astro forums.
Today as cold as it is here, 30 degrees.the temp gauge went past 210 or so and stayed there.When I drove it the last leg home the temps where in the mid 40's and the temp gauge was at like 150.
There was warm air blowing out of the vents but not hot air.
