// About
Built on cooling since 1972
A state-of-the-art radiator shop, a fully stocked parts warehouse, and a crew that has kept the Intermountain West moving for more than 50 years.
// Our story
One family of cooling experts
Since 1972, J-Mac Radiator has served shops, fleets, and industrial customers with every kind of heat-exchange need. With aluminum and steel welding, diesel particulate filter cleaning, and fuel-tank renewal under one roof, we've grown into one of the Intermountain West's most trusted cooling shops.
From heater cores to 10'×10' genset radiators, we repair, rebuild, fabricate and supply — for trucking, mining, oil & gas, construction and agriculture alike.
