Looking at alternative (but still Toyota) heater options for a 1973 SA-spec FJ43. It didn’t come with one from the factory and I appreciate the room above the transmission/below the dash. I live in Portland, so defrost, at a minimum, is required.
I noticed the rear heaters in 60 and 80 series are about as simple as a 40 but slightly more compact. They’re also cheaper than a nice front 40 series blower+heater setup.
The hood vent on the 43 brings in fresh air through the dash, so I’m not worried about needing the 40 series blower’s gate mechanism to get fresh air into the cab.
The vision is to mount an 80 series rear heater/blower unit where the 40 series blower would go in the engine bay and then push that hot air through the defrost vents (for defrost) and then either through holes in the dash or a a vent right below the dash, facing the passengers. There are currently no holes in the firewall for a heater, so I have a lot of latitude around where I place the inlet into the cab.
Any big red flags putting the heater core and fan in the engine bay and tucked up against the fire wall? Anything else I’ve overlooked? The core
