I know you have a 6.0 because you mentioned the coolers, but it would help if we knew what year.
Do you have a valve in your heater supply lines? Is it open? Do your heater supply lines get hot? Both hoses get hot?
The smell sounds like a leaking heater core. Usually you will get a lot of greasy vapor on your windshield. You may not see a leak inside the truck until it gets really bad. But as you know, a leaking core will not cause the heater to not work. Also, some smell after the cooler work is common, along with some oil/water exhaust discharge.
Your core could simply be plugged up, just like your oil cooler was plugged up before the repair. You find this by checking the temp of the hoses coming back out of the core.
Locked up blend doors can also cause this.
Low coolant can cause this. But I doubt this is the problem, because you've had the coolers worked on so you already know to watch the coolant level like a hawk, right?
On '03 and '04 trucks, the water pumps frequently fail internally.
Folks call me Bill. Why, yes, it is a 6 liter. Your jealousy is showing.
i have a single cab
4x4, 6.0, 2004.
i will update my profile...
i read only bigger cabs have a
valve in line? im gonna pull it
ive been on the preemptive attack
recently, and plan on staying ahead
of the game...hopefully
got the truck hot.
the heater inlet hose is warm.
the return hose not as warm..
exposed heater core thru glovebox,
looks fine, vacuum doors are working.
i remember blowing thru the heater
hoses when i was into it last time..
crap, does it look like water pump
the whole time???
thats funny cuz its the 1st thing i started
suspecting before everything.
oil cooler was definitely on its way out
tho when i pulled it.....
well, time to forum search water pump!
Are you getting any white residue around degas bottle cap? When my 04 late build had a no heat problem I tried and checked everything you would normally do for a no heat problem. I finally found it was a very bad head gasket. Fixed that and no more no heat problem!! Also I did not loose much coolant probably because i was not pulling any heavy loads at the time. I figured the head gasket out by hooking up to a heavy trailer and driving and watching the coolant temp. with a AE scan gauge climb out of control rapidly.
wow, new one for me..
i pulled the small coolant hose from manifold
to reservoir, and there was a little flow @ idle...
thanks for that input cuz i woulda never guessed.
im definitely gonna give it the test and scanguage
or use my x3(if its possible) tomorrow.
also, theres no soot or white stuff anywhere.
I still dont get it..........
I never smelled anything when I had no heat, so I'm hoping you are in the clear and it's not head gaskets. I had my heater core replaced at the dealer recently. It wasn't to expensive. Hey, a lot cheaper than a head gasket job!
When I pulled the small hose from intake to reservoir the coolant was mostly foamy.My head gsk. was very bad but i still do not get why it does that! must send more air than water and wont transfer heat to the heater core.
Well, I'm thinking your heater core is plugged up just like you oil was. What I do is disconnect both heater hoses at the heater core, slip a couple of short lengths of hose on the heater core nipples (so they act as stand pipes)and fill the core with CLR and let it sit for 45 minutes then flush it out with a water hose both ways. This procedure really works, I have been doing it for years.
The crew cabs were the only ones fitted with the vacuum heater valve. If you had one, it would be on the supply side (hose closest to fender I think, truck isn't close) between the oil fill stand pipe and the air box.
