I am going to be replacing my water pump on my 1991 Toyota 4Runner V6 SR5. I have the 3VZ-E Engine. I have read that it is a very wise decision to replace the timing belt while you are replacing the water pump because you are already there. Anyone have any past experience or advice they can offer in completing this task?

Thanks,
Brandon

Hi there,

This is a fairly straight forward job, but it will take you a few hrs to complete. Take the usual precautions while doing this type of job, Battery disconnected, remove the spark plugs so you can rotate the engine easily, highlight your timing marks with white out marker so there is no mistake with locating marks (cams at 12-00 Hrs) as is notch on crank shaft pulley. Don't rotate engine with cam shaft bolts. When fitted rotate engine in normal direction of rotation for 2 full revolutions and check timing marks, release tensioner and re tighten again, this will help settle the belt in. Rotate 1 further revolution re check timing marks and all should be well.
