    The Four Seasons 26777 a/c system valve core and cap kit for the 1988 Chevrolet C1500 4.3L / 5.0L / 5.7L / 6.2L and other vehicles replaces the service-port valve core and caps that help keep refrigerant sealed inside your A/C system.

    • Engineered and tested for years of trouble-free operation, backed by over 50 years of Four Seasons mobile A/C experience.
    • Comes with all the seals needed to finish the job.
    • Compatible with both R12 and R134a refrigerants.
    • Suited to SUV and rear air applications.
    • Application specific, matched to the vehicles it fits.

    Weaker cooling, an oily film at a service port or a cracked or missing cap can mean the valve core or caps have stopped sealing, though a leaking hose fitting or worn compressor seal can lose refrigerant too. A shop with A/C leak-detection equipment can find the leak before any parts are replaced.

    The 1988 Chevrolet K1500 4.3L / 5.0L / 5.7L / 6.2L and the 1987-1993 Jeep Wrangler 2.5L / 4.0L / 4.2L get the same direct fit, and so do many other vehicles.
