Check the Cooler and PTO Hole Before You Order
The MAC15 has an 18″ cooler in the lower tank and a power take-off hole cut into the core. Compare both against your old radiator, including the hole’s position, before ordering. Send us your truck’s year and model and we’ll confirm the match.
Built for Heavy Mack Workloads
Mack MR600 Series trucks often work in refuse, construction and vocational service, where heat, dust and stop-and-go duty hit the cooling system hard. A weak radiator is a common cause of overheating. Our guide to common heavy-duty truck radiator problems and fixes covers the warning signs to watch for.
Replace or Repair Your Mack Radiator?
If the damage is limited to a tank or part of the core, repair may cost less than a new unit. See our repair vs. replacement cost guide, or ask about our heavy-duty truck radiator repair and rebuilding and radiator re-coring services. If the radiator is beyond repair, the MAC15 is ready to order.
