CarGurusJan 18, 2015 - I have went in and replaced the water pump and the timing belt. ...Align the crankshaft sprocket (10) with the TDC mark (9) on the oil pump cover. 2. ...and then just shut off and won't restart? try unplugging the cam ... The two timingmarks for the camshafts are lined up and the crank is lined up with TDC.

Well, hopefully the valves were not damaged when the belt broke, If no valve damage was done, get the engine/crankshaft to top dead center, line up camshaft sprocket to timing mark and install belt around pulleys, gears, replace water pump if needed, tension belt if no automatic tensioner is used, try to start to see if it runs and hopefully it will. Might be time for an engine if valve damage was done.

The pistons are hitting the valves due to wrong alignment of timing gears and the timing belt. Align the timing gears and timing belt marks according to the following diagrams.


Good luck.

Remove the t belt and reinstall it. Sounds like you were a half a tooth of on the cams wich would put you a tooth off on the crank. A lack of power makes sense with bad cam timing a s could,very well throw a miss. The misfire did not cause timing to jump

Instructions

1. Remove the Timing Belt 3.0 V6
   • Place the Voyager's engine in the TDC no. 1 position for cylinder firing in order to get proper alignment. Disconnect the negative cable on the battery.
     
   • 2Take off the accessory drive belts, and take out engine mount insulator, located in the engine support bracket. Detach the engine support bracket and take off the torsional damper and crankshaft pulleys. This ensures easier access to the timing belt.
     
   • 
     
   • 3. Locate the 2- to 3-inch wide timing belt in the front of the engine. Remove the cover of the timing belt.
   • 4Mark the course of rotation on the belt as a reference if you plan to reinstall it. Slacken the timing belt torsioner bolt and take off the timing belt. Detach the timing belt torsioner if needed.
     
   • 5Remove the crankshaft sprocket and the flange shield of the crankshaft sprocket. Secure the camshaft sprocket using a spanner tool MB990775, or something similar, and take off the bolt and washer to the camshaft sprocket.
     
   Install the Timing Belt
   • 6Use the retaining washer and bolt to fit the camshaft sprocket onto the camshaft. Utilize the spanner tool MB990775 and tighten the bolt. Mount the crankshaft sprocket and put on the timing belt torsioner and tensioner spring if it was removed. Hook the higher end of the spring to the water pump pin and bottom end to the tensioner bracket with the hook facing out.
     
   • 7Rotate the timing belt tensioner in a counterclockwise turn and tighten the bolt to momentarily hold it in place. Turn the crankshaft sprocket until the timing mark lines up with the timing mark on the oil pump timing mark. Revolve the back camshaft sprocket so that its timing mark lines up with the generator bracket timing mark. Turn the radiator side camshaft sprocket so that the mark aligns with the inner timing belt cover mark.
     
   • 8Connect the timing belt onto the Voyager's crankshaft sprocket, keeping the belt tight on the side of tension. Install the belt in the same rotational direction if using the original timing belt. Put the timing belt on the radiator side of the camshaft sprocket, and place the belt underneath the water pump pulley first, and follow that by putting it over the back camshaft sprocket and the tensioner.
     
   • 9Create tension on the side of the timing belt and correctly line up all timing marks. Put the crankshaft sprocket flange into place and loosen the tensioner bolt to allow the tensioner spring to put tension on the belt. Turn the crankshaft two clockwise turns. Line up the timing marks and tighten the tensioner bolt. Put on the timing belt cover and engine support bracket.
     
   • 10Put the engine mount insulator, crankshaft pulleys and torsional damper into place. Mount the accessory drive belts, connect the negative battery cable and check that the engine runs properly.
     

One side will usually have some slack. This is not unusual. I always remone the spark plugs, and rotate the crankshaft two revolutions. Do this and see if your timing marks are still lined up. Are you tensioning the belt per the shop manual procedure?

You should buy all new belts and a water pump for the car. You will have to take off the power steering belt, the alternator belt, the upper belt cover, support the motor, take off the motor mount, take off the front wheel , take off the engine under covers , line up the TDC timing mark(pulley to cover), take off the lower pulleys, take off the lower cover, take off the timing belt, water pump belt, and now you can unbolt the water pump, scrape the gasket, and replace it. If you put it back together , do not replace the water pump and it goes bad you will kick your self . Now the good news, if you have tools,a compressor, an air gun(for lower pulley bolt), patience , and four to eight hours to kill, you can actually save money and do it your self.

Hello tim42220: y name is Roger and I will help. If the timing belt does not turn when you crank the engine the belt is bad. The belt has a habit of striping the teeth of a the crankshaft gear. This engine shows to be a non-interference engine. That means if the belt breaks the valves should not bend. This is something you should be able to do if you are mechanically inclined. Main thing is to be sure all timing marks are right. I would strongly recommend replacing the water pump at the same time. The water pump is turned by the timing belt. Should the water pump go bad it will also damage the timing belt. They do make a timing belt kit that includes the belt and all new timing belt idler pulleys. You will need to reload the belt tension-er. This is the worst part as it is hard to reset the plunger. Easier to by a new one but they are not cheap. If you look at the new belt you should see two solid stripe markings and one stripe that is a dotted line.I would also replace the camshaft seals as they are the reason for the oil leaking onto the timing belt. When installed correctly the marks align with the timing marks on the engines cam and crankshaft. Enclosed is a picture of the timing marks.Should you need further help please just ask. Please rate your answer. This way I know it helped. Thank You for using Fix Ya. Roger

The only other thing could the the timing belt tensioner if there is any doubt. Here's the timing marks.

Alright, here's a pic of the mechanicals:



The bad news is on your vechile you have to remove the timing belt, but here's a step by step.

1. Disconnect the negative battery cable.
2. Remove the drive belts.
3. Drain the cooling system.

CAUTION When draining coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

1. Remove the timing case cover and timing belt. Refer to Timing Belt Covers and Timing Belt Removal procedures.
2. Remove the pump assembly mounting bolts.
3. Separate the pump assembly from water pipe and remove.
4. Clean gasket and O-ring mounting surfaces.
5. Install a new O-ring on water pipe and lubricate with water.
6. Install a new gasket on pump body.
7. Press the water pump assembly into water pipe.
8. Install pump mounting bolts and tighten to 27 Nm (20 ft. lbs.).
9. Install timing belt and cover. Refer to Timing Belt procedures.
10. Install drive belts.
11. Fill the cooling system

To remove timing:

The timing belt can be inspected by removing the upper (front outer) timing cover.

1. Disconnect the negative battery cable.
2. Remove the accessory drive belts.
3. Remove the timing belt covers.
4. Identify the timing belt running direction to avoid reversal during installation.
5. Loosen timing belt tensioner bolt and remove timing belt.
6. Remove the crankshaft sprocket flange.

To install:

1. Rotate the crankshaft sprocket until timing mark on crankshaft sprocket is lined up with the oil pump timing mark at 1 o'clock position.
2. Rotate the (inner) camshaft sprocket until mark on (inner) camshaft sprocket is lined up with the timing mark on alternator bracket.
3. Rotate the (outer) camshaft sprocket (radiator side) until mark on the sprocket is lined up with the timing mark on the timing belt inner cover. Refer to timing belt illustration.
4. Install the timing belt on the crankshaft sprocket while maintaining pressure on the tensioner side.
5. Position the timing belt over the camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the (inner) sprocket and finally over the tensioner.
6. Apply rotating force in the opposite direction to the camshaft sprocket (radiator side) to create tension on the timing belt tension side.
7. Rotate the crankshaft in a clockwise direction and recheck engine timing marks.
8. Install the crankshaft sprocket flange.
9. Loosen the tensioner bolt and allow tensioner spring to tension the belt.
10. Again rotate the crankshaft in a clockwise direction (2) full turns. Recheck the engine timing. Tighten the tensioner bolt to 23 ft. lbs. (31 Nm).
11. Install the timing covers.
12. Install the accessory drive belts.
13. Connect battery negative cable.

Hope this helps.
