Might help if you list your vehicle and motor in the future or put it in your sig.

Seems like 1 a week (though I keep answering them...)

3 accessory belts and thermostat, unless done in recent past. Don't forget coolant.

 

'98 3.4 Automatic w/ 123k miles, getting a new; Timing Belt, Waterpump, Timing Belt Tensioner, Tensioner Pulley, Idler Pulley, Crank Bolt, Cam and Crank Seals. I'll have it in a few weeks. My truck makes a really annoying humming/whining sound and I've got a feeling it's that. Might be needing a new alternator here soon too.

 

Just finished changing mine out this past weekend, runs so much better.
My biggest problem was getting the crankshaft pulley off... I finally figured if you pull off the plate on the tranny that exposes the flywheel and wedge an allen wrench (the bigger the better) in there you can torque on it without it turning.

And another small tip, invest in some mechanix gloves i tore my hands up without them...

 

already had the accessory belts changed at 110k, now im at 135k, gona get the timing belt etc done at 145k-150k ! thanks for the help guys

 

i am rather clumsy so I make sure to have extra timing cover bolts or any other special bolts that i will lose at the worst possible time.
