Kool Radiator Service, Inc.

Kool Radiator Service, Inc. holds a 4.7-star average across 36 verified customer reviews in Southgate, Michigan. This specialized radiator shop serves commercial and industrial clients throughout the Downriver area, providing repair and replacement services for radiators, charge air coolers, and oil coolers. Their facility handles work for semis, heavy equipment, and machinery, with capabilities that extend to full-service truck repair. The shop operates Monday through Friday from 8 AM to 5 PM, maintaining standard business hours for scheduled appointments.

The business operates as a certified Red Dot dealer and distributor, a designation that signals manufacturer-authorized expertise in cooling system components. Their service menu focuses specifically on radiator systems rather than broader HVAC work, meaning every technician skill centers on diagnosing and resolving cooling failures. This specialization allows them to source parts that other shops cannot find, with one reviewer noting Kool secured a hard-to-locate drain plug that prevented an unnecessary full radiator replacement.

Reviewers consistently highlight technician Shane by name, describing him as knowledgeable and trustworthy. Multiple customers describe scenarios where Kool delivered same-day repairs when other sources quoted multi-week delays and premium pricing. One reviewer with a classic Chevelle appreciated that the shop took time to repair rather than replace his radiator, while another noted the team accommodated last-minute requests. The combination of fair pricing, specialized parts access, and willingness to help with both commercial fleets and personal vehicles creates a reputation that draws customers from beyond the immediate Southgate area.
