Description
SD7H15 6-groove serpentine A/C compressor — Kenworth & Peterbilt
An SD7H15-style heavy-duty A/C compressor for serpentine-belt Class 8 trucks. It runs a 6-groove serpentine 125 mm clutch and the “GSA” vertical pad-mount head that bolts straight to Paccar (Kenworth / Peterbilt) manifold lines — built to HD spec for the high head pressures and long duty cycles these rigs see. Replaces Sanden 4424, 4039, and Paccar F69-6001-122.
Serpentine belt only. This is the 6-groove serpentine version. If your truck uses a V-belt (single or dual groove), this is not the right part — you likely need part #204-1559. Not sure which you have? Call 480-507-2229 and we’ll help you identify it.
Know exactly what you’re ordering
The configuration details that decide fitment on this compressor:

Complete technical specs
Install it right — protect the warranty
Compressor replacement calls for standard climate-control practice to keep the system clean and the new unit covered.
Confirm belt & head
Verify serpentine 6-groove drive and the GSA vertical-pad head. V-belt trucks need #204-1559.
Flush the system
Clear out old oil, sludge, and debris from any prior compressor failure.
Renew components
Fit a fresh receiver-drier and a new expansion valve alongside the compressor.
Set oil & evacuate
It ships with assembly oil — set the correct total system oil, pull a deep vacuum, then charge R134a.
Recommended upgrade: Consider Fluoro-Dye Retrolube POE Oil (861-2112) during install — a premium lubricant with integrated UV leak-detection dye for easier troubleshooting.
