Rare 2004 Toyota Tundra Step-Side: Timing Belt Replacement & Inspection

Rare Step-Side Tundra

• 💡 This video features a rare 2004 Toyota Tundra with the distinctive step-side bed option, a feature that makes these trucks uncommon.
• 🚀 The truck is noted for its rust-free condition and low mileage, approximately 92,000-93,000 miles, making it a well-preserved example.
• 🧐 The V8 engine, a 2UZ-FE, is highlighted as one of Toyota's best, though it requires regular attention to its timing belt and radiator.

Pre-Service Inspection Findings

• ⚠️ A significant oil leak from the valve cover gaskets is identified on both sides, a common issue for this model.
• 🧪 Brake fluid is tested and found to be loaded with moisture, indicating a need for replacement.
• 💧 The original radiator shows signs of micro-cracks and discoloration, suggesting it is nearing failure and needs replacement.
• ⚙️ A worn suspension bushing in the steering rack is noted, which could lead to rack movement when turning.
• axles have been replaced with aftermarket units due to leaks, a decision the presenter advises against.

Timing Belt and Water Pump Replacement

• 🛠️ The process for replacing the timing belt on the 2UZ-FE engine is detailed, emphasizing the importance of precise alignment with T-marks to prevent valve damage.
• 🌊 The water pump is found to be leaking, indicating it also requires replacement during this service.
• 🔧 A new radiator, timing belt kit, hoses, drive belt, thermostat, and idler/tensioner are installed as part of the service.

Engine Timing and Reassembly

• 🎯 Timing the engine is stressed as critical, as the UZ engine is highly sensitive and can easily bend valves if misaligned.
• 🔄 The importance of correct belt tension and alignment with pulley marks at the zero mark (not the T-mark) for reassembly is demonstrated.
• ⚠️ A caution is given regarding the routing of the crank sensor wire to prevent damage from the pulley.

Final Assessment and Video Feedback

• ✅ Despite minor issues like valve cover leaks and brake fluid, the truck is considered in excellent overall condition for its age and mileage.
• ⚠️ The presenter reiterates that rust and timing belt failure are the primary reasons these trucks are destroyed.
• 💬 Viewers are asked for feedback on the video's filming style, with options including time-lapse, live work, and the current style.
