Question strange valve

I have a 03 F350 SD. I was looking under the hood a saw a strange valve in my line that goes to the heater core. What is ? How does it work? Is It good to have it on my new SD? I hope some one out there knows what this thing is?

strange valve

ive heard of some guys putting in a valve to shut off the coolant going to the heater core to make the a/c colder. i dont think that it is needed because the a/c already spits out ice cubes but i guess that it would work. my a/c is cold enough even for texas

With a '03, I don't think that is the case. Do you have a pic of this valve?

It looks like it, but doesn't act like it.

Question strange valve

It says the valve is for the powerstroke, but I can't think of any reason why it would not work on a V-10. Anyone else?

Will it allow flow through the heater core in all other modes?

If so, what exactly is it doing so that it only works in MAX mode?

My a/c does not cool my cab and it has been checked out several times by the dealer.

The news that I am getting is that with that valve in the heater core line. On Max A/C it shuts off the coolant flow to the heater core. On the max a/c you can go fromcold to hot, with no change it the air temp from the vents. I have this on my 03 SD. But the temp still works. It will get hot, on the hot setting. I talked to the dealership, they said that in works the way it's suppose to. But this mod shuts down coolant in the max a/c setting. It is the same thing. Why does ford's valve act different? Some one must know the answer. I hope I could get my point across.

I'm knocking this back to the top since the last two posts had questions that have gone unanswered. (and I had one of them! )

Can anyone help out?

I just added the heater core shutoff to my 2000 gasser... it works just fine, although I need a hot day to see if the AC is noticably cooler.
