Heater box question?

Post by ryneb21 on Mon Aug 04, 2014 5:19 pm

Quick question..I get mixed results when searching the samba. My 78 bus has heater boxes. They come up and into the engine bay as typical heater boxes do. On my baja I have the fan shroud AND the holes in the heater boxes blocked. Should I also block the boxes on my bus? I assume the air from them is just getting up into my engine compartment. Leave em open or block them off somehow? Thanks!

Here is how it works you can not just block air going to heater boxes you will over heat everything. There is a temperature controlled blower fan that hangs above engine and needs to be 100% functional. Those that block off shroud and leave heater boxa are misinformed. If you block up shroud you must remove heater box's and use j tubes. Hope that helps

Yeah I've heard diff. And since it's the 2.0 it doesn't have the fan shrouds like the old motors. If I don't have the fan what do I do? Just leave em open?

Fix it !! you should run the fan just like the factory designed it. Or lose the heaterboxs.

Are your heaterboxs in good condition or do they need to be replaced.

Thank you! So it says the pipes coming trough engine Tim from hear exchangers dot need to be left open. But it doesn't say what to do with then. Could I just connect the two with a hose for now? Or just cap em off? No time or money to fix before the trip.

The heatsink in the heater box is what's killing it for you. Best yo remove metal ductwork between heater box and upper engine tin so the heat doesn't get pullled back into the fan. The openings left on both tins must be cleaned and sealed best to use metal tape or formed sheet metal piece to fill hole. This is still only a doctored situation and still must be addressed . the electric blower fan and air tubes and all of your engine bay sealed is best. You also must have the performed foam seal around engine bay. You have to keep the heat out of the engine bay . remember cool clean air on top hot dirty dirty air on the bottom.
