Truck Parts by Make, Model & Year.

AIR CONDITIONING

Semi Truck A/C Expansion Valve: Symptoms, Testing and Replacement

It is the cheapest part in the A/C system and it fails by imitating the most expensive one. The five symptoms, what both gauges tell you, and why 27 valves carrying 1,669 OE cross-references cover forty-seven years of trucks.

COOLING SYSTEM

International Cooling & A/C Problems: ProStar, LoneStar, 9900i and WorkStar

The number on an International is a class code, and it decides the whole cooling package. Why our 67 radiators for the marque span core heights from 17.75 to 51.6 inches, how the A/C loop actually fails, and the 15 coolant tanks we stock — more than for any other make.

COOLING SYSTEM

Mack Cooling & A/C Problems: Anthem, Pinnacle, Granite, CH and CX

Mack model codes tell you what the chassis was built to do, and that decides the cooling package. Why our 31 Mack radiators span core heights from 26 to 50 inches, how highway, vocational and refuse Macks fail differently, and doing the A/C job once.
