About Us

Kirk's Radiator & Auto Air Conditioning was established by Leonard "Kirk" Newkirk in 1948 after he served with the Navy in WWII. Kirk's Radiator & Auto Air Conditioning is still family owned and operated by Kirk's son Stan and his son Ryan. Kirk's Radiator & Auto Air Conditioning started out doing only radiators, then began doing air conditioning repairs in the mid-1960s. In 1999, we began doing mufflers and exhaust work as well. We service all makes and models of cars and trucks, as well as customs, heavy-duty and industrial equipment. With years of experience, we perform repairs for many of the school districts and fire departments in the county, as well as Cal Trans, CDF, the County of San Diego and the cities of El Cajon, Santee and La Mesa. We work on many customs and exotics where radiators and air conditioning systems need to be custom built or fit. We also specialize in custom and performance exhaust. It's our commitment to quality, integrity and service that make us the choice of many municipalities as well as thousands of satisfied San Diego residents.
