Hello,

Today I spent some time working on the heater for Sublime. I knew I wanted some sort of heater because in Wisconsin it's cold more often then warm. I salvaged the heater box and fan from the Metro when I was ripping it down. I used a grinder and cut away most of the heater box, only leaving enough to have a cold air intake and exhaust. I also ground down the plastic around the heater core only leaving a plastic shell that wrapped around the more fragile radiator. I wanted to mount it in the seat tunnel. I cut in the cold air intake in the seat tunnel close to the floor under the dash and had to make a wood carriage to hold the heater core. The fan and heater core were built so I could replace either one if need be.The unit is sealed in under the dash only allowing air to go to the defroster vents and 2 vents on the tunnel. The downside is a 12" wide spot on the dash right in front of the tunnel where I won't be able to put any controls or gauges. I have to clean everything up yet, coat with epoxy and do the final install.

Box cut in on seat tunnel, little bit of black silicone to clean up those edges.

Heater core just slides in.

A removable panel to seal it up.

avatar Great idea and nice work.
For me, here in deep texas, I don't think I'll be
needing a heater for a while.

I noticed you have residue inside your heater core. If a cooling system is
clean, inside and out, it transfers temperature much better. Think of it as
insulation.
An awesome and very easy way to clean your whole cooling system is
with automatic dishwasher soap. Pick a time when it is above freezing, drain
your cooling system, fill with water and about a half cup of automatic dish
washer soap, put your rad cap back on. Run the unit for as long as you like, but
an hourish is usually enough, just make sure you get to temperature and
circulate your rad. I even block the rad sometimes to help heat it up, but watch
you do not overheat. Drain, refill with water, run to rinse, drain, reinstall
antifreeze.
Look down your radiator befoe and after and watch what you drain
out. You will be amazed how well it cleans.
This will help any cooling system.
But if you have used an "internal radiator repair" gunk, it will wash it
out too and you will have to repair it properly. Mike

avatar Terry,
I believe it was a 94. I had to cut them down quite a bit to make them
that small. Nice thing was you could see where you needed to cut them to make it
work.
