    In the early 1970s, Mazda strengthened its reputation worldwide driven by the success of its rotary engines which had proved to have many advantages if compared to the competition. The RX-4 was released in late 1972 and debuted in the U.S. market in 1974. It was available as a hardtop coupe, 4-door sedan, and later, as a station wagon. The luxurious, sporty Mazda RX-4 offered high performance while meeting the new strict 1975 emission standards both in the United States and Japan. The RX-4 received minor changes through the years and remained in production until 1978 when finally, it was replaced by the RX-7 series.

    The RX-4 embodies the distinctive for Mazda combination of performance, comfort, and reliability, but it doesn’t mean that the vehicle doesn’t require special care and attention to maintain this magical balance and efficiency. The A/C and heating system is particularly sensitive in such vintage cars as the RX-4. If you have detected some problems, visit our website and browse our catalog of top-notch replacement components, including Mazda RX-4 A/C & heating parts.
