What This Condenser Is and What It Bolts Into
This is a full aluminum condenser assembly, not a repair coil — it mounts in front of the radiator/charge air cooler stack on 579s and T680s built 2022 through 2024. PACCAR shares a lot of chassis architecture between the Peterbilt and Kenworth lines these days, and the A/C module is one of the places that shows up clearly.
PX936001 covers both trucks because the mounting points, tank locations, and port fittings are identical — this isn't a coincidence, it's the same PACCAR part number under two nameplates. If your truck is in that 2022-2024 window and your old condenser has a PACCAR tag or one of the numbers we cross below, you're in the right spot.
Why F3112831112010 and F3112831121010 Cross Over
Those two numbers are Peterbilt/Kenworth service numbers that reference the same condenser assembly — one may reflect a running production update or a slight revision in packaging, but the physical part is the same casting and tank setup. This kind of dual-numbering is normal on PACCAR parts once a supplier updates a part mid-run without changing form or function.
Where you need to actually look close: port O-ring size and thread pitch on the inlet/outlet, plus the mounting tab spacing top and bottom. On these MX-cooling-package trucks it's been consistent, but a running change on brackets isn't unheard of. Pull the tag off your old unit or find the number stamped into the tank before you order — don't go off model year alone.
Ordering From PartStop
We keep this one in stock in Tacoma for will-call or same-day pickup if you're local, and we ship nationwide for the guys who can't wait around. A dead A/C condenser on a 579 or T680 in July doesn't care about your schedule, so we try not to make you wait either.
This is aftermarket, comes with our 6+ month warranty, and we'll get it out the door fast. Just confirm your VIN or the number off the old condenser before you buy — cheap insurance against a return shipment.

Frequently asked questions
Does PX936001 fit my 2023 Kenworth T680?
Likely yes if it's within the 2022-2024 build window with the standard MX cooling package, but confirm with your VIN or by matching the number on your current condenser — PACCAR has run more than one cooling configuration across these years.
Is PX936001 the same as F3112831112010?
They reference the same condenser assembly, yes — different point in the parts catalog or a running production update, not a different physical part. Match your old tag number to be sure before ordering.
Can I use this condenser on a Peterbilt 579 if my truck also has a charge air cooler right in front of it?
Should work fine — the condenser mounts independent of the CAC on these trucks, but check your mounting tabs and hose routing against the old unit since some spec packages shift bracket positions slightly.
