    Timing belt?

    Ugh. Kid got 03 vue. 3.0 motor. Been told it is similar to catera 6? U take off belt and all 4 cams need to be retimed? Wtf? Each tensioner needs to be tweaked to change timing of adjacent cam? Like bank 1 and 2? Is this really a piss poor job or what?

    Re: Timing belt?

    The L81 was used longitudinally in Cadillac Catera and transversely in the Saturn L-Series, Saturn Vue, Saab 9-5 and Saab 9000.

    If you rotate the engine so the #1 piston is at TDC, you will not have to re-time the cams, just make sure you do not rotate the crank when the timing belt is off.

    If there is a mistake in the cam timing, you can ruin the engine as this is an interference engine. You will need new heads and possibly (most likely) new pistons, depending on the position of the valves when they hit the piston.

    This is not a job for the beginner mechanic as there are a lot of parts to come off the front of the engine as well as draining the coolant (Do not allow any to go down the drain or into the ground as it is highly poisonous). You will also have to do an oil change afterwards.

    When you are putting on the new belt you need special holders to hold the belt to the cam sprockets so they do not move when you tighten the belt tensioner, among other things.

    If you are going to attempt it, look around the boards for a manual (I got them here) that explains the procedure.

    Read a lot on locking cam sprockets together. Crank and cams are aligned. U rotate motor and check cams timing. If its off, u tweak tensioner slightly. Kit seems pretty simple. U clip for sprockets is simple. How or where to get a sprocket timing guide is the hard part.
