Product Introduction C4316845 Air Conditioning Compressor serves as the refrigerant compression unit for heavy trucks powered by ISZ13 engine. It works with the condenser, evaporator and expansion valve to circulate refrigerant, absorbing heat inside the cab and releasing heat outward to achieve cooling. This aftermarket replacement compressor fixes intermittent cooling, high-pitched squeaking noise and refrigerant escape brought by damaged internal piston components, failed clutch assembly and degraded shaft sealing of old units. Reliable cooling function helps drivers stay comfortable during long trips under hot summer weather.

Product Advantages Lightweight aluminum alloy shell balances strength and heat conductivity, resisting continuous vibration from engine operation. Precision internal movement assembly maintains stable compression ratio across different engine speeds. The built-in clutch responds quickly to switch cooling on and off. Every unit passes refrigerant pressure test and clutch engagement inspection before leaving factory, port positions match original AC piping without extra modification work.

Applicable Models Designed for heavy-duty commercial vehicles equipped with ISZ13 diesel engine, commonly used for long-distance highway freight transport.

FAQ

Q1: How does moisture inside the AC circuit harm the compressor?
A1: Water reacts with refrigerant to form acid, which corrodes internal precision parts gradually.
Q2: Can a slipping AC clutch reduce cooling efficiency significantly?
A2: Yes, friction loss on clutch surface cuts power transfer and leads to insufficient compression output.
Q3: What can be checked visually before installing this compressor?
A3: Check the pulley runout and confirm no debris blockage in the surrounding cooling air path.
