Efurd Garage I noticed the smaller one has 3 or 4 vents that need modifying if your going to run ducting. I think I’ll make a template the size of the unit and mock it up behind the ac delete plate. Sucks I have the LS ecm there but oh well
Well if it has coolant in it and the engine is over 130 you should feel heat. I would check flow and engine temp. Make sure its not getting an air pocket
@Efurd Garage thank you for the reply... appreciate that! I'm looking into this one to add to my old datsun 240z. Acouple guys done it before. Do you remember what size fuse it requires? And if the heater core in it is replaceable?
i dont see why you couldnt, its adjustable so you can change the angle. you could also just find a way to run the ducts to the windshield, really as long as you can fab or come up with something it could really go anywhere.
If your thermostat is okay, then it could be that the pump cannot pump the water easily to go the extra distance through the cooling lines. Go to Amazon and get a Bosch Automotive Electric water pump. Add the pump to the coolant line before the core. The circulation will be more efficient this way. No harm.
