So I'm replacing the water pump on my 2008 xB. Just had a couple quick questions... do I need to jack the engine up to replace it?
Do I need to loosen the idler pulley to take the belt off? This is my first time doing a water pump and my tools are limited.

I just did this repair with my much more skilled mechanic friend.

Tips:

You need to remove the alternator to get to the water pump. Unhook the battery, then remove the alternator.
Unhook the engine mount on the passage side. Jack the engine up slightly to give you easier access to the pully.
Loosen the bolts for the water pump before loosening the tension on the belt. Did this the hard way.
Drain the radiator, unhooked the coolent jug and moved it out of the way to make more space.

i went on 2008 Scion xB Parts - PartsGeek
Purchased the gates brand water pump.
It comes with a gasket seal. Set the seal in the groove of the water pump for a day or two before hand. That way it sits in the groove naturally. I think I paided like $45 with shipping for the part. I also recommend doing the pull tensor at the same time and throwing on a new serpentine belt.
My scion 2008 xb has 144k. Be sure to clean the area where the engine and water pump meet really well. Scrape all that stuff off.

With as much of a PITA this is dont go cheap on the pump, I used a Bosch on my xB1 and it died after 20K. I ended up replacing it with a Aisin/Toyota, the cost was $61 vs the $46 for the bosch but at least I wont be replacing it for a while.


When the pump goes out on my xB2 I'll be going with an Aisin/Toyota.
