    Well I've read search results on heaters and yes there is a bunch of it here.Of all the threads I have found, I haven't run across what I was looking for.
    I just wondered if anyone has tried using thermostat bypass coolant to feed one of the heaters on a Jeep with two heaters. It seems to me that more flow could be realized and possibly warmer as well. Instead of using coolant that has been cooled by the first heater core/radiator the second or other heater could get fresh out of the manifold coolant?
    It has been a number of years ago I checked the temp between the cores and there was a surprising
    drop between the first and second heater.
    I guess unless someone tells me I have rocks in my head,the thing to do would be to try it.

    Until the thermostat opens, the coolant isn't cooled by the radiator. After it does open, and stabilizes, the coolant is just as hot.
    I installed an aftermaket heater, and plumbed it before the factory unit. It heats so well, I don't even use the factory heat, so I don't know if it is compromised... I know, no help here.;)

    It's Moab from Summit, made by Heater Craft. If you search, you'll find threads about it.

    You need to run the heaters in parallel, tee the inlets and the outlets together. This will give full temp to both heaters.
    Don't run one heater into the other(series)
