Our History

Clyde MacDonald founded Mac’s Radiator in 1947 in a small wooden building on Foster road in SE Portland. In a short time Clyde (soon joined by his cousin Frank MacDonald) had outgrown the original building and built the first of many additions to the Foster location. The business was continuing to grow when the unexpected death of Clyde in 1962 brought his two sons Jim & Phil into the business. Phil, who had more experience in the business, took some time off from dental school to help out and teach Jim the business. In the coming years after Phil had returned to dental school, Jim continuing his father’s tradition of customer service and forward thinking expanded the business to service air conditioning systems and industrial radiator manufacturing. As the business grew so did the family; Jim had five children, who all of whom spent time “helping out” as they grew up. Lisa, the oldest daughter went off to become a schoolteacher, working summers throughout college. Steve joined the business full time after graduating high school, as did daughter Diana, and youngest son Curtis.

Starting in the late 70’s Jim began adding locations, starting out in the Portland area before spreading out to Washington and Idaho. In 1997 Jim handed over the management of the company to his three children. Since Jim’s retirement, Stephen has been acting President. Working alongside Stephen is his sister Diana Debray and brother, Curtis MacDonald. Since taking over from their father, Steve expanded Mac’s custom fabrication department to include high quality show and classic car radiators plus air coolers along with heavy duty industrial radiators from some of the leading equipment and motor home manufacturer in the country. In February 2006 when a sudden and fatal heart attack took company president Stephen MacDonald, Jim temporarily came out of retirement for a year to help navigate the company thru this difficult time. Over the next several years Jim’s daughter Diana and Son Curtis shared the responsibilities of directing the company and with a team of key employees made some tough decisions during the worst economic downturn since the great recession. During this period, the decision was made to close 4 locations and streamline many back office operations along with developing of new products and strategies to help ensure our long term viability.

One important aspect of this was the developing and manufacture of a line of heavy duty steel replacement expansion tanks for school buses and semi trucks. This has grown into a important part of our business that we are now distributing across the U.S. through our network of dealerships. With this growth our manufacturing department recently moved it into a new building set up specifically for the process and enough room for continued growth. Mac’s also move forward to develop all of our locations into complete automotive repair facilities to enable us to take care of not only our customers Cooling and Air Conditioning needs but all needed vehicle repairs and services. As part of this ongoing process our Boise Idaho location moved into a beautiful new 12 bay location on a major highway.
