Yaris leaking water pump - Toyota Yaris Forums

I don't have the manual on hand right now for torque specs, but I've always just hand torqued them really snug by hand and had no issues.

I don't know about a specific DIY but it is straight forward, here are the steps I did:

Remove the 3 14mm bolts that mount the mount to the engine bay wall. You also need to remove the 1 10mm bolt holding the a/c line onto the mount (can't remember if that applies to the '08 Yaris or not)

Remove the 3 bolts that attach the mount to the egine itself. There are 2 on the top and one hidden underneath, I believe they may be 12mm not entirely sure.

You will need a socket and an extender to make it easier. An air ratchet is a bonus but definitely not needed.

Make sure the jack w/ wood is under the oil pan before you start the job. Once bolts are removed remove the mount. You may have to turn and twist the mount to remove it. The alternator will need to be removed first.

Once the mount is removed you can jack the engine up and down which allows very easy access to all of the bolts on the water pump (3bolts and 2 nuts).

Re use the original metal gasket, if it is damaged than just use some water pump safe RTV which works just as good, just don't over apply it.
