The 3.0 V6 belt removal is a fairly easy process if you are mechanically inclined. For the simple mechanic it is a doable job but you will need a good puller for the crankshaft drive pulley. Disconnect and remove the battery from the vehicle. Basically you need to remove all the belts for the alternator AC and power steering pump. Remove the fan guard Fan radiator and fan assy. This allows you access to the belt covers. Remove the top cover to gain access to the belt. You can then inspect it and see if it needs to be replaced. If so then turn the engine by until it is at TDC and the timing marks on the cam shaft are lined up with their marks. Then pull the crankshaft pulley and the lower cover. Loosen the belt tension mechanism and remove the old belt. Clean the pulleys before installing the new belt in the reverse order. The new belt will have marks and maybe it wont. I put the belt on anywhere and then reinstall the crank shaft cover so I can see the TDC mark. Make sure the belt is on the lower pulley good or you will have problems. Then its a matter of moving the belt around and getting it tight with all the timing marks lined up. I do the bottom one first then the right one and finally the left one. (viewed as looking at the engine from the front of the car). Then once completed reinstall all the pieces in reverse order. Best bet go get a Manual from Chilton and can walk you through the whole thing step be step. It is an all day affair for most of us but is do able.
