Hello all Lincoln LS experts. My problem. I have no heat and I thought by replacing the upper radiator hose and degas bottle may fix the issue. I followed the proper procedure when filling with coolant and this is not my first rodeo as I have had several ls vehicles and had same issues with all of them. My question is IF I CAN NOT GET A STEADY STREAM THROUGH THE HEATER BLEED COULD A DCCV BE MY PROBLEM? FYI THE ONLY TIME I CAN GET ANY STREAM FROM THE HEATER BLEED IS BY REVVING UP THE ENGINE AND IT WILL GIVE ME A CONTINUOUS STREAM FOR ABOUT 2 SECONDS THEN NOTHING MORE.. PLEASE HELP.
2000 Lincoln LS v6 will NOT SHOOT STEADY STREAM FROM HEATER BLEED

Yes it could, but there are other possible causes too. Can you see any coolant leaking from the DCCV?

BTW, when you replaced the degas bottle, did you use OEM, or Dorman or Dorman rebranded? If Dorman, that could be your problem. If you run the engine up to operating temperature, then loosen the degas cap, do you get a hiss of pressure being released? If not, you have one or more leaks somewhere.
No I dont see any coolant leaking from it I just know the heater wont work at all not even on the highway
I will try this in the morning and get back with you. THANK YOU
No never replaced and car has 174k miles

OK Gang. Heres what I know today. I drained and refilled with antifreeze using the correct procedure. Still no steady stream from the heater bleed valve and No heat in the car.. So I began to start feeling the hoses going to and from the dual climate control valve. Oddly the hose going to the DCCV from the upper radiator hose was not hot even though the Upper radiator hose was very hot. CRAZY CAUSE THIS IS THE SAME HOSE THAT JUST Y's OFF THE UPPER RADIATOR HOSE. SO NO HOT WATER IS EVEN REACHING THE DCCV ALLOWING IT TO CIRCULATE THROUGH THE HEATER CORE. IS THIS A DEAD GIVE AWAY THAT I HAVE A BAD DUAL CLIMATE CONTROL VALVE?

Sounds like you could have a clogged heater core. Mine is like this. Seems like a real hassle to flush it out, but it's likely a mineral deposit in mine. It just got worse and worse over the years. It takes only 5 minutes to get the engine temperature needle to normal temp, but it takes 20 minutes before the heat can be felt. When I first got the car, I could feel heat at the end of the driveway at work, with scarcely any temp gauge movement, but now, with 265K (miles) on it, it's dismal. If your DCCV was working, but your cores were clogged, you wouldn't see much hot water travel from the DCCV. Thinking about the way the system operates, it may be that the used heater water is what flows to the DCCV, if that line goes to the upper radiator hose. I recall troubleshooting once and feeling very hot water on one side of the heater core and cold on the other, indicating next to zero flow. Mine eventually gets the cabin comfortable, but that's little consolation for having a 25 minute commute. https://www.youtube.com/watch?v=dcL_0TWeZJY

For the stuff he uses to clean out the core but does not show its CLR. I use it all the time to flush cores.

Thank you all so much for your help. I want to be sure you guys are understanding my previous post. Nothing is even getting to the Heater Core because it has to go to the DUal Climate Control Valve First Right? *The hose going to and from the Dual Climate Control Valve is cold when the car is at running temperature. The upper radiator Hose has a split connection that runs down to the DCCV and the upper radiator hose is hot but the link running to the dccv is cold, Not HOT. *It seems to me that the DCCV is closed shut not allowing water to run down into it therefore creating an air pocket in the hose that runs to the dccv then through the heater core. So In summary Water is not even going to the DCCV and therefore it would be impossible to say that the Heater Core is Blocked RIGHT? Or maybe im wrong please let me know your thoughts.. and thank you so much for all your willingness to help. HAPPY HOLIDAYS

I think that it is unlikely that both heater cores are blocked. It can happen, but you don't hear about it much on the LS.
Just to be clear, any blockage anywhere in the heater loops will cause the whole loop to remain cold.
If the blockage is in the heater cores, then you have to have two blockages. (very rare)
If the blockage is in the DCCV, then you have to have two blockages. (rare, but heard of)
If the blockage is in the return hose, then you would only need to have one blockage.
If the blockage is in the supply hose to the DCCV, then you would only need to have one blockage.
If the V6 is like the V8, then the upper radiator hose has a plastic screen that can get plugged that would block off flow to the heater system.
If the heater never worked since you bought the car, it's possible that someone put plugs in the heater hoses instead of fixing a bad DCCV.
