Another thing to consider is the heater core is a parallel flow design. That means that half the core could be clogged and you would still have flow through it, but only half the heating ability. Sometimes you can't effectively flush out something like that because there is more than one passage for the water to flow through.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I have had some success with filling the heater core with CLR and letting it sit for 20 min or so, then flushing core again. Only as last resort, since its not recommended by manufacturer. Ive never had it cause a problem with a core, but I suppose it could, so I dont do it unless the only other option is replacing the core.

yes there is plenty of air flow, but the filter is a very good point, not sure if it has ever been serviced. I will note that thanks. I timed it this morning a 10 min run and it was putting out heat. temp climbed a good bit when rpms were brought up to about 2000. all seems well

a point I did not consider, core orientation. another engineer design flaw LOL. inverted the other way would seem better,
just not sure if air would be an issue. thanks for your point

another thought i had considered, even more so now given the orientation of the core. my goal was to fix the problem but was only going to consider replacement as a last resort. time will tell as she drives the car. still holding the part for a few days.

Re: 03 honda element no heat

just a thought, why would the manufacture suggest a fix when they would much rather sell the labor and parts LOL,
tricks of the trade, what we learn when we just don't follow what we are told. or apply a bit of critical thinking.
thank you

It's not so much the orientation, but the flow design. It doesn't take much to clog up those small transfer tubes. You may not be able to use water flow through the inlet and outlet pipes to flush out the clogged tubes, because the water flow will go through the good tubes. Water is going to flow through the path of least resistance. That is why radiator shops have to remove the tanks on radiators to rod tubes out.
edit:
Good to see you got it figured out. Closed per request by OP. Can be reopened upon request.

Tell me toolman the orientation of the blower motor to the heater core if you would as I can't look that up? Some you get a good view of it and can touch it or IR thermo it to see if it's got a cold spot. Flow on this stuff as DS brought up may not be straight line for cleaning out so easy or at all.
All but so very few are a LOT of time and careful attention to just remove and replace plus little crap and things can break easily, how well sealed and with what messed up. Hate them as you can see. There's no doubt to me that everything is tight for work space in this and about everything
Never mind what a new one costs but what a waste of time if not conclusive to change it out and be done with this problem,
T

It's been very clear throughout this question that he has a temperature problem, not an air flow problem and a plugged up heater core is the only possibility out there. He has already determined that by the temp of the heater hoses.
His only options at this point id to either get it flushed which has been futile for the reasons DS pointed out or replace the core.

Was on PMs about this with him that's it's open. He can take it out (very used to dash work as an auto body guy) and will try to clear it or replace. Waiting to get some funky temp measuring stuff that I'm about sure will prove it has cold spots or whole area.
It's the challenge now not the bucks. Might be good archives for what sealer can really wreck. Of all things in the junk fix isles there should be one that reverses effects of stuff of the sort that really works IMO! Tom
PS: @ HT. Do you recall the brand name Zerex antifreeze? 1960s or so. TV ads they poked holes in the gallon jug of it and it sealed them! Haven't seen the brand name on anything. It wouldn't or couldn't be useful on H.E. cooling systems and was supposed to be proactive not after the fact. Never used it then either.........

Back when radiators were copper and the passages were like tunnels. That stuff was pretty harmless back then. Not any more.
