It should last the life of the engine and is normally replaced during an engine overhaul.
It has a timing belt.
It depends on the engine. I have a 2002 Camry XLE with a 4cyl which has VVTi and it has a chain.
It has a chain, they should be replaced every 100,000 but I had an 1987 Toyota pickup with 230,000 and never replaced a thing on it and it ran like a dream. if your truck is running bad then replace it if not. then don't waste time
Your 2004 Toyota 4Runner has a timing belt if it is a V8. This belt must be replaced every 90,000 miles. Warning: This is an interference engine. Severe engine damage will be done if the belt breaks. If you have a V6 then it has a chain which should last the life of the engine.
This engine has a timing belt. Needs to be changed at 90,000 miles. All seals and water pump should be replaced at the same time.
No, it will normally last the life of the engine and is replaced when the engine is overhauled.
By 2007, most Toyota vehicles did not have a timing belt. They were equipped with a timing chain, that does not need to be replaced due to a time or mileage limit. If you were more specific with the engine/model, I could let you know for sure. Also their may be an drive belt that is needed to be changed on the outside of the engine. This belt should drive the water pump, alternator, power steering, etc.
It does not have a timing belt. It has a chain..all 2003 Toyota Corolla Trims S, CE and LE have the same engine, the 1.8Liter 1 ZZ FE, The only engine Toyota makes anymore with a timing belt is the V8 that comes in the Tundra, Sequoia and 4Runner
It 12 years old you should have it serviced perhaps the seals need replaced, an are sure it's the Trans leaking and not the engine.
