Cooling and heating systems play a critical role in the overall operation of your 1966 LeMans, helping manage engine temperature while also supporting a comfortable cabin environment. These systems work independently but rely on many of the same components and airflow pathways throughout the vehicle.
OPGI offers 254 Cooling & Heating parts designed to support both engine cooling and climate control functions. From radiators, hoses, and cooling system parts to heater cores, controls, and related components, you’ll find quality products from trusted brands including Old Air Products, Maradyne and Vintage Air to help maintain proper temperatures, improve efficiency, and ensure consistent performance.
Every purchase is backed by our Price Match Guarantee. Plus, with OPGI’s 60-day return policy, you can shop confidently when selecting parts for your 1966 LeMans. Orders ship quickly, or you can visit our Southern California showroom to see select components in person.
