Tool kit to remove and install injector sleeves/cups without pulling engine heads for the 7.3L Power Stroke and Navistar T444E engines. These Sleeve Tools are 100% Made in the USA using USA materials!
The 7.3L Power Stroke injectors sit in a brass sleeve that separates the injector, and fuel, from the engine's coolant. These brass sleeves weaken and fatigue from age and tend to split and fail. A common symptom is finding fuel in your cooling system. This happens because the fuel system typically operates at around 60 psi of pressure, whereas the coolant system operates at a much lower pressure so the fuel gets pumped into the coolant when the sleeve fails and cracks.
We offer these custom made tools to simplify the changing of the sleeves. By design, the tools are shorter than an injector so you can change the sleeves with the heads on the motor and the motor still in the truck since there is no slide hammer required like with some other sleeve tools. These tools are Black Oxide Solid Steel for long life. You can replace your sleeves as preventative maintenance now, or replace them later once you detect signs of failure.
