And you can see it's driving the alternator, and 2 other pulleys... presumably the water pump, and getting its drive off the crankshaft via the bottom pulley, so regardless of the terminology anyone applies, you won't get laughed at if you call it an alternator belt. If you're replacing it, take note of the recommended tensioning, and achieve that result by pivoting the alternator to a higher position before tightening the bolt securing the alternator in place. Some folk like to claim that getting this wrong can ruin the water pump. I suspect most of those claims are made by mechanics who want to get paid to do a schoolboys job. DIY and keep the money in your wallet. Those that don't aren't worthy of their chest hair, or their other supposedly manly bits. If the belt squeels when going through 1st gear after cold starting with a lot of drain on the electrics (eg headlights, fans, demisters all running) then you've got the belt a tad loose (which is better than being too tight). The squeal however will make you wet yourself if you're not familiar with it's simple cause and low significance. It's definitely not a biggie.	Paul.Cov (425)

Shouldn't need to touch the head to change a cambelt. Loosen tensioner (or remove if it's a one time deal) and remove belt, replace belt in same position. Note that twin cam engines usually require two people, or two steady hands to hold cams in position, while putting new belt on. But pic is "fan belt" might be electric fans but for the sake of simplicity it is an accessory belt and is a 5min job to replace. Chances are it has an auto tensioner on it but if not just tighten the tensioner until it's tight but still has enough give that you can move the longest stretch of belt 10mm with pinched fingers. Overtightning will only damage the belt and result in it flying off or snapping. Too loose and it will slip which you will hear (squeeeeel). Easy Peasy	hueybot3000 (3646)
