I AM GETTING VERY LITTLE HEAT OUT OF THE HEATER

1995 Volkswagen Eurovan • 58,000 miles

Hi,
I have no problems with over heat of the engine. No water in the oil or oil in the water so, I do not think it's the head gasket. The van runs great! The temp gauge waw running very low, I put in a new thermo, did not help. The instrument gauge runs very low but higher than before. I checked the water temp with a food thermo, 170deg. I had a time bleeding the air out of the system when I changed the thermo. I am wonder if I still have air in the heater system. Do you have to bleed that in the back someplace? What in the world am I missing? What service manual do you recommend? Thanks for the help.

Haynes or Chiltons. They're usually less than $20 at stores like Autozone, O'Reilly, Pep Boys, and Advanced.

Do the hoses leading to and from the heater core both get hot?

I know this is an old post, but if someone else is reading this.

Could be faulty heater flaps, more specifically missing foam on the
flaps. When the foam is missing, air flow can not be directed as it
just passes through the holes in the flaps (see attached image).

Removal of heater box & disassembly will be necessary to fix problem.

Look through the floor heater vents too see if flaps are missing
foam insulation.

I worked on a 1995 Cabrio yesterday. Had the same problem, lack
of heat.

I turned the blower on high and saw foam pieces fly out of the vents.

This is a common problem on older VWs.
