Water Pump Belt, IS300h.

[Paul Brooksbank]

My neighbour had his Nissan X Trail brought home last week in a recovery truck, his serpentine belt had snapped on the motorway. Anyway, I picked a new belt up for him the next day and fitted it in about half an hour. The Nissan has a tensioner pulley that you move against spring pressure using a spanner, very easy.

This prompted me to take a look at mine and I was surprised to see only one little belt between the crankshaft pulley and the water pump, but I can't see any mechanism for tensioning the belt. 

Anybody done one?

Yes the is300h does not have a belt tensioner. Its just a stretch belt that drives the water pump. Its super simple and easy to replace the waterpump and belt if needed. Full thread here

Thank you very much. That makes sense having looked at it.
