If the timing belt broke, he should take it to have it replaced because theres more than likely to be bent valves in the head. Heads should be checked before putting another timeing belt on. If there is valve damage, then more than likely there damage to the pistons too.

SOURCE: need marks for timimg belt

On the crankshaft gear there is a VERY small dimple that aligns with a mark on the motor. The mark on the motor (a small triangle) is at roughly 11 o'clock. After you line these timing marks up look at the camshaft gear and you will see that on one of the spokes there is a hole. You need to use a mirror to line this hole up with the dimple on the cover that is behind the camshaft gear. (It is at roughly 1 o'clock) If this hole is 180 degrees from where it should be you need to rotate the motor 1 more revolution at the crankshaft and it should now be lined up, or close. Once lined up I like to take a silver (metallic) Sharpie and make my own mark on the camshaft gear and on the backing plate that is behind it. You can make this mark where ever it is convenient for you. As long as you know where your marks line up, that is all that matters. This way I don't have to use the mirror as often.

  • Step 5 Once you have your timing marks aligned you need to locate the tensioner. The tensioner obviously keeps the appropriate amount of tension on the timing belt.

    Timing Belt & Sprockets Removal & Installation 3.2L Engine To Remove:
    TDC compression stroke timing marks gm_car_cad_cts_04_tmg_mrks_tdc_comp.gif

    1. Before servicing the vehicle, refer to the precautions at the beginning of this section.
    2. Remove or disconnect the following:
      • Timing belt cover
      • Crankshaft damper
    3. Rotate the crankshaft in the engine rotation direction, clockwise using the J 42098 or other suitable tool until the # 1 cylinder is at Top Dead Center (TDC) on the compression stroke. The reference marks on the camshaft gears should be aligned with the corresponding notches on the rear timing belt cover, as well as the mark on the crankshaft sprocket and oil pump housing. Timing marks 60 degrees from TDC gm_car_cad_cts_04_tmg_mrks_60_frm_tdc_comp.gif

    4. Rotate the crankshaft counter clockwise using the J 42098 or other suitable tool until 60 degrees Before Top Dead Center (BTDC). The 60 degrees BTDC point can be identified by the index mark on the oil pump cover. Using the J 42069-10 or other suitable tool gm_car_cad_cts_04_j42069-10.gif

    5. Install the J 42069-10 or other suitable tool to the crankshaft sprocket with the knurled bolt.
    6. Rotate the crankshaft in the engine rotational direction, clockwise using the J 42098 until the lever of the J 42069-10 or other suitable tool firmly contacts the water pump pulley flange. The # 1 cylinder is at TDC at this point.
    7. Secure the moveable lever of the tool to the water pump pulley flange. Tools in cam gears gm_car_cad_cts_04_tools_in_cam_grs.gif

    8. Install the J 42069-1 and the J 42069-2 or other suitable tools to the camshaft gears. If the J 42069-1 or the J 42069-2 or other suitable tools do not fit into the teeth of the camshaft gears, it may be necessary to loosen the upper idler pulley and turn the eccentric or camshaft gears until the tool can be inserted.
    9. Loosen the timing belt tensioner nut.
    10. Loosen the upper idler pulley bolt.
    11. Remove or disconnect the following:
      • Lower idler pulley bolt
      • Lower idler pulley and spacer
      • J 42069-10 or other suitable tool from the crankshaft sprocket WARNING
        After timing belt is removed, never turn camshaft and crankshaft independently. Do not remove J 42069-1 and the J 42069-2 or other suitable tools while the belt is removed.

    Cadillac cts 2003 3.2l engine the timing belt jumped time i replaced the set it back on the timing marks an it didn't start i a code po 341 so replaced the camshaft position sensor didn't start

    The same thing happened to my 03 CTS. The camshaft position sensor code is often thrown for a variety of reasons. In my case somehow the ECM went when the timing belt jumped (after the serpentine belt broke). It was a bear to diagnose but after installing a rebuilt ECM it runs great. (Don't make the mistake I made: the cylinder head gaskets will fit nicely on either side but if not placed on the correct sides you'll block the single oil port which provides engine oil to the head)

    Timing belt broke intalled new one and need to set timing on 1992 toyota corolla

    Not sure I understand your question.
    If you did not move the distributor, and the marks are lined up on the cam and crank gears, the timing should still be correct.

    Engine timing

    If all your marks are right there is a process for seting the timing that some people are not aware of. Did you jump the terminals at the data link connector (number 1) ? If you did not the toming will never set itself. Below is the proper procedure for setting the timing. Make sure your idle is at 700 + 50 and in nuetral. Hope this helps. The botom picture is the location of the data link connect (DLC1) that needs to be jumped.

    Location of timimg marks on a 1986 ford ranger with a 2.3 engine

    1. Locate and carefully remove the access plug from the upper portion of the timing cover. WARNING
      When turning the engine over by hand, ALWAYS rotate the crankshaft in the proper direction of rotation, otherwise the timing belt might jump one or more teeth due to the configuration of the belt tensioner.
    2. Turn the engine CLOCKWISE (in the normal direction of rotation) to set the engine at Top Dead Center (TDC) of the No. 1 cylinder by aligning the O mark on the belt cover with the O mark on the crankshaft pulley. NOTE: If no timing mark is visible through the access cover when the O marks on the crank pulley and cover are aligned, the engine may be on No. 1 exhaust stroke and not the compression stroke (the camshaft is 180°away from No. 1 TDC). If so, the crankshaft must be rotated one full turn to bring the No. 1 piston back to the top and the camshaft around to close the No. 1 intake and exhaust valves.
    3. With the O marks aligned, look through the access hole in the cover to confirm that the timing mark on the camshaft sprocket aligns with the pointer on the inner belt cover. If the belt timing is incorrect, the timing cover and belt must be removed for further inspection, possible replacement and correct installation. For more details, please refer to Section 3 of this manual.
    4. If timing is correct, re-install the access plug. prev.gif next.gif
