2006 Chevrolet W5500 Tiltmaster

The 2006 Chevrolet W5500 Tiltmaster is a medium-duty cab-over truck designed for commercial applications, offering good maneuverability and visibility. This particular model year offered a 5.7L Vortec V8 gasoline engine producing around 300 horsepower and 360 lb-ft of torque, as well as a 7.8L Isuzu inline-6 diesel engine rated around 200 horsepower and 441 lb-ft of torque. The available transmissions included manual and automatic options depending on the engine. Owners typically appreciate the truck’s tight turning radius and ease of maintenance due to the cab-over design. Dislikes often revolve around the cab’s spartan interior, ride quality, and potential for specific engine and transmission issues as the truck ages.

Engine

5.7L Vortec V8 Gasoline

• Oil Leaks
  • Description/Symptoms: Oil leaks are common, often originating from the valve cover gaskets, oil pan gasket, or rear main seal. Symptoms include visible oil drips under the truck, a burning oil smell, and low oil level.
  • Solution: Replace the leaking gaskets or seals. The valve cover gaskets are relatively straightforward, while the oil pan and rear main seal require more labor.
  • Estimated Cost to Fix: $100 - $200+ for valve cover gaskets, $300 - $800+ for oil pan gasket, $500 - $1200+ for rear main seal.
  • Recalls: None Found
• Catalytic Converter Failure
  • Description/Symptoms: The catalytic converter can fail over time, especially with higher mileage. Symptoms include a check engine light (usually a P0420 code), reduced engine performance, and a rattling sound from the exhaust system.
  • Solution: Replace the faulty catalytic converter.
  • Estimated Cost to Fix: $300 - $800+
  • Recalls: None Found

7.8L Isuzu Inline-6 Diesel

• Injector Issues
  • Description/Symptoms: Fuel injectors can become clogged or fail, leading to rough running, poor fuel economy, and excessive smoke.
  • Solution: Diagnose the faulty injector(s) and replace them.
  • Estimated Cost to Fix: $200 - $500+ per injector.
  • Recalls: None Found
• Turbocharger Problems
  • Description/Symptoms: The turbocharger can develop leaks or fail due to wear and tear. Symptoms include a loss of power, excessive black smoke, and a whistling or screeching noise from the turbo.
  • Solution: Inspect and repair or replace the turbocharger.
  • Estimated Cost to Fix: $800 - $2500+ depending on repair vs. replacement.
  • Recalls: None Found

Transmission

No Issues Found

Suspension

• Leaf Spring Sagging/Cracking
  • Description/Symptoms: The leaf springs, particularly in the rear, can sag or crack due to heavy use. This leads to a lowered ride height, poor ride quality, and reduced load-carrying capacity.
  • Solution: Replace the worn or damaged leaf springs. Consider upgrading to heavier-duty springs if the truck is frequently used for heavy loads.
  • Estimated Cost to Fix: $500 - $1500+ per axle, depending on spring type and labor.
  • Recalls: None Found
• Worn Shocks
  • Description/Symptoms: The shocks can wear out, resulting in a bouncy ride, poor handling, and excessive body roll.
  • Solution: Replace the worn shocks.
  • Estimated Cost to Fix: $200 - $500+ per axle.
  • Recalls: None Found

Electrical

• Wiring Harness Issues
  • Description/Symptoms: Due to the cab-over design and frequent tilting of the cab for maintenance, the wiring harness can experience wear and tear, leading to broken wires, corroded connectors, and intermittent electrical problems.
  • Solution: Inspect the wiring harness for damage and repair or replace as needed. Clean and protect electrical connections with dielectric grease.
  • Estimated Cost to Fix: $100 - $1000+ depending on the severity and location of the damage.
  • Recalls: None Found
• Alternator Failure
  • Description/Symptoms: The alternator can fail, resulting in a dead battery, dimming lights, and eventual engine shutdown.

  • Estimated Cost to Fix: $200 - $500+
  • Recalls: None Found

Exterior

• Rusting Cab
  • Description/Symptoms: Cab rust, especially around the windshield, door seams, and lower body panels, is common in areas with road salt.
  • Solution: Repair rust with bodywork and paint. Prevent future rust with rustproofing treatments.
  • Estimated Cost to Fix: $300 - $2000+ depending on the severity of the rust.
  • Recalls: None Found

Interior

• Dashboard Cracking
  • Description/Symptoms: The dashboard can crack due to sun exposure and temperature changes, especially in hot climates.
  • Solution: Replace the dashboard or use a dashboard cover.
  • Estimated Cost to Fix: $200 - $800+ for replacement, $20 - $50+ for a cover.
