No heat diagnostics
Yeah all my Jeeps I've owned & my LR's have much better heating systems than say my 2014 Ram work van which takes at least 15 miles to even start feeling warm.
Another way to check heater core flow is with a laser thermometer. Just aim it at the input/output lines and you'll instantly know if there is a huge difference in the temps as well.

My heater core was plugged.. Would not put out any heat... period. I flushed back and forth with a garden hose through the hoses going to the heater core.
Found out it was plugged and it finally blew through. Now I have plenty of heat.
I have only tested to around 20 degree F., but found the Disco to have the fastest warming heater out of all my cars.

you know... I don't really know. I had so much water going everywhere, all I know is it started flowing slowly and then finally started flowing well.
Looking back, I am not so sure it was such a good idea to use so much pressure. I sealed off my garden nozzle to blow through. This could have ruptured the o rings or worse blew the core out.
Here in SoCal we have very high water pressure because so many houses have fire sprinklers. Not so sure putting 80-100 psi of water at the core is good.
Luckily it dont leak and I now have great heat.

Most cases? Most cases it's simply been airbound.
