IMPORTANT INSTALLATION NOTES:
✔ Use clean, filtered engine oil (≤40 micron); maintain proper oil pressure and temperature to prevent wear
✔ Ensure coolant flow (min. 2.5 GPM) with correct routing; do not exceed 266°F (130°C)
✔ Maintain proper oil drain through mounting flange; do not block passages or use sealants
✔ Keep intake restriction below 20" HO and use high-efficiency air filtration
✔ Use correct discharge line size (min. 0.547" ID) and route downward to avoid buildup
✔ Do not exceed 190 PSI discharge pressure or 3000 RPM operation
✔ Maintain proper tilt limits to ensure lubrication (max 30° rotation, 10° static tilt)
✔ Use minimum 1/4" ID governor line; keep short and unrestricted to avoid pressure fluctuation

EL365 reman got my C15 back on track
The check valve being pre installed saved some time, and all the mounting surfaces were true. I did need the elbow kit, so anyone ordering this should plan for that. Once everything was torqued and coolant and oil lines were hooked up, the compressor came to life right away
