Description
Sanden SD7H15 A/C Compressor — 8-Groove, 12V (Blue Bird Bus & Truck)
A complete SD7H15 compressor assembly with the clutch already fitted — an 8-groove poly-V pulley (119 mm), 12V clutch, direct / cross-bolt mount and KC cylinder head, on R-134a. One of the most widely used bus and truck A/C compressors.
The heart of the A/C system
The compressor pressurizes and circulates refrigerant through the A/C system — without it, there’s no cooling. This is the complete SD7H15 assembly, clutch included, for these bus and truck applications.
When the original compressor is noisy, seized, or won’t engage, replacing it with a fresh unit is the core of an A/C repair. Because debris from a failed compressor spreads through the system, a proper install includes flushing and replacing the drier and metering device.

Technical specs
Installing a new compressor? Flush the system, replace the receiver-drier or accumulator and the expansion / orifice device, and follow the correct oil charge before you evacuate and recharge. Skipping these steps is the most common cause of a repeat failure.
