An inspection and some ramblings regarding my Tundra as it reaches 400,000 miles. The engine (5.7l V8 3UR-FE) and transmission are still original.
Some maintenance and repairs from 250k-390k miles:
Oil changes every 5-7k miles, using 0W20 full synthetic
Intake valley coolant leak repair (251k)
Secondary Air Injection pump (270k), repaired first then bypassed when it failed again.
Water pump (280k, probably the 3rd water pump)
Starter (285k)
Front CV axles (302k)
Brake pads and rotors only once, one rear brake caliper
Transmission services: Dealer flush at 251k, drain and fills around 310k, then at 380k that I did myself
AC compressor, condenser, expansion valve, fan clutch at 330k, then another compressor and condenser this summer around 385k because I had a refrigerant leak that I didn't address.
Radiator, radiator hoses, thermostat, serpentine belt tensioner and another serpentine belt (387k)
