I'm wondering if I should attempt to change the timing belt in my 4runner or take it to a dealer / shop. I've read in the forum that the belts last to 150k and others say replace them at 90k / 7 years. I have 162k currently, belt was replaced at 74k by a Toyota dealer. It runs fine, no leaks or issues.



So my questions are:

is the engine (3.4 liter v-6) a non interference engine or not?



what should I pay to replace the belt, water pump and tensioner?



or should I attempt it myself if cost is over $500.00. I have a shop and sufficient skill (with a factory manual at hand) and tools to do the work.



Your suggestions please.
