Check Before Ordering
Match the cap to the radiator actually installed in your vehicle. Aftermarket radiators can require a different cap from the original radiator. Confirm both the filler-neck fitment and suitability of the 1.3 kg/cm² pressure rating.
This is the Type-S cap. Applications requiring the Type-N flat-style cap use a different part number, 591-A004.
