Tune UpAccording to the Toyota website your vehicle isn't due for a tune-up for 120,000 miles.
Recommended at every 25,000-30,000 miles
Every 80K miles, 100K max.
I just spoke with a Parts person at a local Toyota dealer. He told me that the 2004 Toyota Matrix requires Iridium spark plugs, which retails for about $12 at the dealership, and it should not need to be changed until 120,000 miles.
Should be changed every 60,000 miles. This is NOT an interference engine.
I think they recommend to change it each 160-180K miles.
100,000Km
The transmission fluid on a Toyota Sienna should be changed every 100,000 miles. This helps to prolong the life of the transmission and improve performance.
The engine oil should be changed at least every 3,000 miles on a 1985 Toyota Tercel. An automobile this old should also have the oil and air filters changed at the same time for the motor to run move efficiently.
I have found that the filter should be changed around 90K in normal use and 60K in severe conditions. Toyota Tech.
If the engine has a timing belt, it should be changed around the 150K mark. If there is a timing chain, it does not have to be changed unless it is damaged.
