Procedure

1. 1

   Drain engine oil
   Locate the engine oil drain plug on the bottom of the oil pan. Position drain pan underneath. Remove drain plug using appropriate socket and allow oil to drain completely (approximately 10-15 minutes due to high capacity). Inspect drain plug threads and replace drain plug washer.
2. 2

   Replace engine oil filter
   Locate the engine oil filter on the engine block (verify exact location against factory service documentation for the 8.3L V10). Use oil filter wrench to remove old filter by turning counterclockwise. Clean the filter mounting surface on the engine block. Apply thin film of fresh oil to the new filter gasket. Install new filter hand-tight, then tighten an additional 3/4 turn. Do not over-tighten.
3. 3

   Refill engine oil and verify level
   Reinstall engine oil drain plug with new washer and tighten securely. Add 7 quarts of 5W-40 full synthetic oil through the oil filler cap. Start engine and allow to run for 30 seconds, then shut off. Wait 2 minutes for oil to settle. Check oil level on dipstick and add remaining oil to reach full mark (total capacity approximately 8 quarts with filter — verify against owner's manual). Inspect underneath for leaks at drain plug and filter.
4. 4

   Replace engine air filter
   Open hood and locate air filter housing on the driver side of the engine bay. Release the housing clips (typically 4 clips around perimeter) and lift the top of the air box. Remove old air filter element. Inspect housing for debris and clean if necessary. Install new air filter element ensuring proper seating. Secure air box cover and engage all clips.
5. 5

   Inspect and service rear differential
   Locate the rear differential fill plug and drain plug underneath the vehicle. Remove fill plug first to ensure it is not seized before draining. Remove drain plug and allow gear oil to drain into pan. Once drained, reinstall drain plug with new washer. Using fluid transfer pump, fill differential with 75W-140 synthetic GL-5 gear oil (with limited-slip friction modifier additive if required for the limited-slip differential) through fill hole until oil begins to seep out. Reinstall fill plug.
6. 6

   Inspect and service manual transmission
   Locate the transmission fill plug and drain plug on the side and bottom of the transmission case. Remove fill plug first. Remove drain plug and allow gear oil to drain completely. Reinstall drain plug with new washer. Using fluid transfer pump, fill transmission with the factory-specified synthetic manual transmission fluid (verify correct Mopar/ATF-type fluid for the Tremec T56, approximately 3.6 quarts) through fill hole until oil reaches the bottom of the fill plug opening. Reinstall fill plug.
7. 7

   Inspect brake system and fluid
   Inspect all four brake calipers, rotors, and brake lines for wear, leaks, or damage. Measure brake pad thickness at all four corners; pads should have minimum 3mm remaining material. Check brake fluid level in master cylinder reservoir. If fluid is dark or below minimum line, extract old fluid using turkey baster or fluid pump and refill with fresh DOT 4 brake fluid to MAX line. Check brake pedal feel during test drive.
8. 8

   Inspect cooling system and top off coolant
   With engine cold, inspect all coolant hoses for cracks, soft spots, or leaks. Check hose clamps for tightness. With engine cold, inspect coolant condition at the pressurized reservoir/degas bottle; G-05 HOAT coolant should appear yellow/amber. Note: this vehicle uses a pressurized coolant reservoir rather than a conventional radiator cap. Check coolant level in overflow reservoir; should be between MIN and MAX marks. Top off with Zerex G-05 HOAT 50/50 coolant if needed. Inspect radiator fins for debris or damage.
9. 9

   Rotate tires and inspect suspension
   With all wheels removed, inspect tire tread depth (minimum 2/32 inch) and wear patterns. Check for uneven wear indicating alignment issues. Note: the Viper uses staggered (different-sized) front and rear tires, so front-to-rear rotation is NOT possible. Do not rotate front-to-rear; inspect wear only, or perform side-to-side rotation only if tires are non-directional and same size on an axle. While wheels are off, inspect all suspension components including control arms, ball joints, tie rod ends, and shock absorbers for wear, leaks, or damage. Check for torn boots or excessive play.
10. 10

    Reinstall wheels and set tire pressure
    Install rotated wheels onto vehicle, threading lug nuts by hand initially. Tighten lug nuts in star pattern to proper torque specification. Lower vehicle to ground. With vehicle weight on tires, perform final torque on all lug nuts in star pattern. Set tire pressure to specification listed on the driver door jamb placard (do not assume equal front/rear pressures; the Viper uses staggered tires — follow the exact placard values).
11. 11

    Inspect drive belts and tensioners
    Visually inspect serpentine belt for cracks, fraying, glazing, or missing ribs. Belt should not show excessive wear at 30K miles. Check belt tensioner for proper operation and smooth movement. Inspect belt routing and ensure alignment on all pulleys. Look for oil contamination on belt which could indicate leaking seals.
12. 12

    Lubricate chassis and inspect driveline
    Inspect driveshaft and U-joints/couplings for wear or play. Note: the Viper uses a one-piece aluminum driveshaft (no center support bearing) and the U-joints are typically non-serviceable with no grease fittings. Inspect driveshaft boots for tears. Check exhaust system for leaks, damage, or loose hangers. Inspect fuel lines and fuel tank for leaks or damage.
13. 13

    Perform final underbody inspection
    Conduct comprehensive inspection of entire underbody. Check for any fluid leaks from engine, transmission, differential, or brake system. Verify all drain plugs are secure. Inspect frame and body for damage or corrosion. Check exhaust heat shields for security. Verify no tools or materials have been left on or near vehicle components.

Reassembly

1. Ensure all drain plugs, fill plugs, and filter caps are properly tightened.
2. Verify all wheels are torqued to specification after vehicle is lowered.
3. Double-check that no tools, rags, or parts have been left in engine bay or under vehicle.
4. Reset maintenance reminder if equipped with maintenance tracking system.

Verification

• Start engine and verify no warning lights remain illuminated on instrument cluster.
• Allow engine to reach operating temperature and verify coolant level remains stable.
• Inspect ground under vehicle after 15 minutes of run time for any fluid leaks.
• Test drive vehicle for 5-10 miles, verifying smooth operation, proper brake function, and no unusual noises.
• After test drive, recheck engine oil level and all fluid levels to ensure proper fill.
• Verify tire pressures are at specification after test drive with warm tires.
• Perform final visual inspection of all service points for leaks or issues.
