Review on Dayco 89007 Tensioner Idler Pulley by Sean Maile

Just a warning that this pulley will work properly on a Nissan 4.0 engine but if it gets completely wet the poly V-belt will slip. I installed this on my Nissan Xterra which was built for off road and well water protected engine bay but if water gets on this pulley it will slip right off. unless you ride off-road and in dry climates a great pulley, but anywhere it's wet I'd spend the extra money on a factory pulley.
