it is a job i wish on no one it can be done with motor in van the motor kindof sets flat on this vehicle you will have to remove all kinds of things just for access it is a job for someone that has done it before. i have worked for toyota for 25 years and i would pay someone else to do it.ha ha the good thing i can tell you is those timing chains never wear out unless you got 250,000 miles if you can hear it rattle at idle it needs replacing if you are doing it just for maintance dont do it good luck

Yes it is possible but it will be tricky considering the engine placement. If I'm not mistaken it has a belt and not a chain.

it isn't impossible you just have to to get i new one like for pep boys,auto zone or you get one from a juck yard
