No Heat
So, like many people, the single digit temps are impacting my rover. After reading all the posts, I thought I would throw my hat in the ring for an opinion.
The vehicle heated up fine, got to operating temp in the expected amount of time. However, warm air never came out of any vents.
In the past, if i put the temp to "max", i do not get as hot air as if i only set it to 84 degrees. Also, the vents to do not put out consistent air temps, the front vent may be much warmer than the foot or window vent.
Any thoughts on where to start?
One other question, my power steering was painfully loud this morning, likely due to cold. Is there something that needs to be done?
Thanks,

Remove your heater hoses & reverse flush out the heater core. I literally just did this yesterday! I had calcium deposits in my heater core from the previous owner using more water vs coolant. 230K on my D2 so no biggie. I bought 5ft of 5/8 heater hose, cut off the old heater hoses taking care not to tug on the heater core lines (you DO NOT want to damage the heater core lines/O-Rings). Flushed out the heater core backwards to push the crap out vs thru it, removed the 8mm bolt securing the second heater metal line to the other, carefully rotated it out of the way, cleaned off the metal line ends, slid the 5/8 line on it with a little WD40 to make it slid on easier, then I cut to fit the line. I did not put the heater core lines back into their OEM criss cross pattern. I went with the RRC setup straight in/out. Once done with the inner line rotate the outer lane back into position, and re-install the 8mm bolt, then slid the outer 5/8 hose on, and cut to fit as well. Secure them up with new hose clamps, and boom you’re done.When flushing the core I’d run it backwards at first and let it flow until it’s good and clear then flush the other way for good measure. After that run the D2 and check for any leaks, you should start getting heat, and the in/out hoses will be warm (I checked mine before I did any work and only one was warm. The other line was stone cold). Also for maximum heat make sure ECON mode is selected so the AC compressor doesn’t run. While my heater core was clogged I had zero cooling issues, just zero heat.

It’s a clogged core man, no biggie.

Yep if you grab the 4-5ft of 5/8 coolant/heater hose, 4 new clamps, the hardest part will be removing the old stuck on hoses. It’s a 20min fix, but yes a garage is a must.
