Hello All,
This is Alan in Las Vegas. I have a 1996 4X4 Dodge Dakota with a 5.2 litre Magnum V8 engine.
My question is: Can someone tell me where I can buy an orifice tube extraction/installation tool for this model?
Thanks in advance for your help.
Alan

Yup. I think it is also called an "expansion tube". In my case it is located inside the input to the the evaporator. It locks in place deep inside the pipe and requires a special tool to unlock and retract it. It's a must replace item if you are replacing major a/c components and if you are having the a/c system flushed. (all according to the Haynes A/C manual)
Regards,
Vegas Al

You can buy the tube (actually a small filter screen) at any local auto store (Orielly's, Autozone, NAPA, etc.). I have never worked on Dodge A/C system's, but all of the Chevy systems I have worked on never required a tool to service, but if it does require one I would imagine the parts store should also carry it.

Hey Alan, what is your complaint? There is no orifice tube in your Dodge. You have an H-block or "expansion block" bolted to the evap. at the firewall. It's not as prone to plug up as the Chevy tube. See! Dodge is better!

I have a '98 with 60K and it is the poorest quality A/C system of any car I've owned. I have had two Chevy '87s both with colder A/C systems than the one in my Dodge.

My 1997 Dodge Dakota has an orfice tube and it is out front in the exit of the condensor. It slides down inside the tube. No tool needed.

I have a 2000 Dakota 4.7L and you have to replace the whole tube where the 'Orifice' tube fits into cause the screen just can't be replaced. Dealer Item only. I hope this helps. Ron G

Let me clear something up before this turns into a chevy/dodge argument page. I forget what year but all older vehicles had R22 refrigerant instead of the R134a we have now. R22 is more efficient and made for a better cooling A/C system..hands down no matter what manufacturer. The EPA didn't like what leaking R22 does to Ozone so they mandated R134a which is why your 97 or whatever is not as cold as the 87...will never be.

I'm having trouble finding mine on my 97 Dakota, I
Thought it was in the tube coming up from the
condenser a few years ago... I tried to replace it
then but just like you I couldn't get the dang thing
out... I know have been told to get compressed air
and hit it from the other side of the line, so I was
going to try that but danged if I can find the tube
now... I'm confused. Anyone have a pic of this?
