GT Radiator Repair was founded in 1980 by George Turner, Sr., his wife, Edna, and their two sons, George Jr. and Harry.

The family operated their own trucking business and realized the need for reliable, dependable, and knowledgeable radiator repair service for their trucking fleet. As a result, they purchased the necessary equipment and became trained in the repair of car, truck, and heavy equipment radiators. For over 40 years, GT Radiator Repair has been located at 161 South Main Street in Ambler, Pennsylvania.
