Heater Core

[logistix]

On my 1996 Blue Bird TC2000, I have a Cummins 5.9 Turbo Diesel. I took out the rear heater under one of the seats. Can I cap both of the coolant hoses or should I join them together with some copper pipe?

If I don't have a rear heater anymore, does the coolant still need to circulate up to engine block?

Hook them together, it needs to be a complete loop. I presume that all of your heaters, including front defroster is on the same loop, most are. If you have a FE you can eliminate everything in the back as long as you keep the loop.

Yes I have an FE. Thank you for the advice! I will install a nice copper loop tonight to ensure it flows properly.

I ended up getting two 6" pieces of brass tubing that were threaded on the ends and shoved them down into the rubber hoses leaving the threaded part out to connect a 12" heavy duty washer hose that that was metal braided reinforced on the outside. Very flexible and strong. Maybe this winter I will replace it with a heater if my Dometic Duotherm in the front ceiling of the bus doesn't perform well enough.

If it's a heat pump, then you may well be supplementing it with a heater. Heat pumps don't do very well below 40F. You may have a heat strip on it. The heat strip is "supposed" to heat well enough. But they do suck a bit of power. Not a problem if the electric is included with your site rent.

If you are going to be in a cold weather climate you will need the heaters....... The heatstrips in the AC units are there for them cool mornings.....
They will assist the hearer but not replace it.....

My vote would be keep the heaters...
good luck
