I'm having some AC issues and wanted to replace the orifice tube. I bought the car with the KC on it and I'm trying to figure out where the orifice tube is. I saw that the tube is crimped in the tube, but that tube has been replaced with a KC tube. Any ideas?
Orifice tube in Killer Chiller
- Thread starter Davisenvy
- Start date
Here is the instruction manual. Not sure if this will help or not.
No clue on placement check with killer chiller before replacing it with a factory 1, the reason i say this is because on a 6.0 diesel when i installed a air to oil cooler from bullet proof diesel the directions stated if the vehicle ac didn't cool as good to remove the ford style orifice tube and use xxx from a chevrolet (guessing it has something to do with more of a strain on the system). Natedogg posted the manual before i finished but I'm still posting lol.
The ac worked great then one day it just quit working. I have normal low side pressure, but high side is going way too high (45 low and 350-400 high side) which makes me think I have a blockage somewhere. I saw the directions on their site but it doesn't say anything about the orifice tube. I tried to call KC and no answer. I might just take the thing off if I can't figure it out. Thanks for the replies.
The link above - page 16 of the file, marked as 15 on the paper - #10 says ac inlet with orifice tube. It’s in the killer chore core on the inlet side
It's in the A/C inlet from condenser (#8 line) shown in the instructions.
Keep in mind there are multiple generations of Killer Chillers so your heat exchanger might look different. The older ones had the coolant fittings on top and the AC fittings on the bottom, like this:

Awesome info and thanks for the picture. Looks like the front bumper might need to come off. At least I know where to start. Thanks again.
Am I not supposed to use a orifice tube with the KC? I'm trying to track down a blockage and thats my first item to check.
the factory one gets removed and the KC supplied one goes into the KC core instead
Just to follow up, I have the older generation KC and the orifice tube was exactly where you said. It was also completely caked up so I replaced, recharged and my AC is working perfectly. Thanks for the help.
