Product Description
Cracked or split injector sleeves on the 7.3L Powerstroke can allow diesel fuel to leak into the cooling system. Over time, this leads to contaminated coolant, overheating issues, and even coolant reservoir overflow.
The Sinister Diesel Fuel Injector Sleeve (Injector Cup) is designed as a direct replacement to restore proper sealing between the injector and cylinder head. Built from high-grade materials, this sleeve provides a precise fit and reliable long-term protection against fuel-to-coolant leaks. It’s a smart preventative upgrade whenever injectors are serviced or replaced.
