I was shoveling another two feet of newly fallen snow (more coming to Spokane this week) to get my truck out the other day and while I was pondering the anemic nature of the heat in the truck I got to thinking.

The build tag has a statement about a standard duty heater...this begs the question of is there a heavy duty heater core available? This would be for a 1982 D-150 without air conditioning, Slant Six of course. Would a heavy duty heater core merely be a replacement for the existing core (i.e. would it fit inside the existing heater/blower housing)? Aside from the fact that swapping the heater core is sure to be a PITA is there any other stuff to consider?

My rig has new weatherstripping, new windshield, new rear window, new carpet (with added insulation). It needs some new foam seals/weatherstripping for the floor vents but other than that it is tight. It is a truck--metal is the headliner material, one assumes that there is no insulation between the metal sandwich of the interior "headliner" and the metal roof.

So, any information on "heavy duty" heaters out there?

Thanks...

Most auto makers offered cold weather packages. This usually included a block heater, a fan with fewer blades, and possibly a larger heater core. I don't think you would need one in Spokane. I would make sure your current system is working right with no clogs or crap in the system.

There is no "heavy duty heater". The '82 Dodge truck/van FPC shows one heater core for vehicles with A/C, and a different core for vehicles without A/C. Looks like you could get an auxiliary heater as an accessory. But the stock heater will do just fine as long as the whole heating and cooling system is in good condition, repair, and adjustment.

Ok-dokie. Looks like I will have to go leak hunting to get things warmer...

tirol,

Check your thermostat. When I put the current motor in my car i noticed a significant drop in heater performance. I suspected a stuck-open t-stat and pulled the housing. Lo and behold, no t-stat at all. Popped in a new 190° unit and it blows hot now (my girlfriend even asks me to turn it down sometimes! That in and of itself is remarkable). Does your temp gauge read on the cold side? That's a good sign there's something up in the t-stat department.

Just my ¢2

My '73 D100 came with what was called a "Deluxe High Output Heater"...code MB3.

As far as I know, the core was the same, but that heater fan would pressurize the cab to about 20,000 feet and the roar was enough to cause ear damage, but that sucker would put out the heat!

I drove it in -30F weather, and it would roast you out.

Is the fan motor different or does it just have a different fan wheel?
