MEI Airsource, AC Delco and Motorcraft offer heater cores to replace original heater cores in Fords, GMC, Peterbilt, Mack, IHC, Freightliner and more.
Heater core applications can be determined by cross referencing the original equipment heater core numbers, lookup by year make model application and by dimensional size.
Heater core dimensions are determined by measuring the width/height, length and thickness. The width/height of the heater core is measured along the fin. The length of the heater core is measured along the actual core only. The length of the heater core is the length of the coils between the header segments. Thickness is the thickness of the heater core coil only.
