Coolant Reservoir Cap for Freightliner FLD and Peterbilt trucks.
Replace the coolant reservoir cap, and not the entire tank, on your Peterbilt or Freightliner FLD. All of our Coolant Reservoir Caps are constructed of high-quality plastic. They protect the cooling system by providing a tight seal against the elements and prevent splashing or leaking. Free Shipping.
