There are rotation index marks on each new filter spaced 90 degrees apart, to be used as a guide for tightening. 4. Make sure oil is visible on the dipstick.5. Start and run engine for a few minutes. Inspect for leaks.6. Stop the engine.7. Maintain the oil level between the ADD and FULL marks on the dipstick. 8. Add oil if necessary.9. Clean and install the dipstick.Fuel System
Wash Primary Filter Element
Challenger 65C/70C (2YL1-UP and 2ZJ1-UP)
Do not fill fuel filters with fuel before installing them. Contaminated fuel causes accelerated wear to fuel system parts.
The primary element is located on the right side of the engine, below the priming pump. 1. Shut the fuel off at the fuel tank. A fuel shutoff valve is located under the fuel tank, near the center on the front face.
Failure to shut fuel off when changing filters causes fuel spillage.
2. Loosen filter housing retaining nut (1).3. Remove housing (2) and element.4. Remove the element from the case.5. Wash the element and housing in clean, nonflammable solvent.6. Dry the element using pressure air - 205 kPa (30 psi) maximum.7. Clean the filter case base.8. Inspect the seal. Replace if it is damaged.9. Insert the clean element.10. Install the element and case into housing.11. Retighten the retaining bolt to a torque of 24 4 N m (18 3 lb ft).Replace Secondary Fuel Filter

Install the new filter element by hand. When the seal contacts the base, tighten 3/4 turn more.There are rotation-index marks 90 degrees apart on the filter. Use them as a guide for proper tightening.5. Prime the fuel system. (See next topic.)Priming the Fuel System
1. Unlock and pull out the priming pump plunger.2. Operate the pump to fill the new filter elements with fuel. Continue pumping until resistance is felt, indicating the elements are full of fuel.3.
