cylinder head and timing
Okay new here and I'm hoping someone can help...
98 Dodge Stratus, 2.4, interference engine Vin X
The timing belt broke (at a very very low speed so not worried about the valves yet). Replaced timing belt, water pump, Idler pully, plugs, wires and camshaft sensor. When I go to start it it seem to have initial spark and then runs like it's free spinning with no spark. I'm wondering if replacing the crankshaft sensor will fix this or is there something more i need to do with the timing marks? Someone said I needed to hook this up to a computer to get the timing lined up right but everything I have read doesnt say anything about that. Can someone please help me with some ideas, sugestion or anything to get this monster running? I have attached a picture of the way the timing should look and have had it spot on but still have the same issues..

INSTALLATION - TIMING BELT
Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing.
Set camshafts timing marks so that the exhaust camshaft sprocket is a 1/2 notch below the intake camshaft sprocket (Camshaft Sprocket Alignment).
CAUTION: Ensure that the arrows on both camshaft sprockets are facing up.
Install timing belt. Starting at the crankshaft, go around the water pump sprocket, idler pulley, camshaft sprockets and then around the tensioner (Timing Belt Installation).
Move the exhaust camshaft sprocket counterclockwise (Timing Belt Installation) to align marks and take up belt slack.
Insert a 6 mm Allen wrench into the hexagon opening located on the top plate of the belt tensioner pulley. Rotate the top plate COUNTERCLOCKWISE . The tensioner pulley will move against the belt and the tensioner setting notch will eventually start to move clockwise. Watching the movement of the setting notch, continue rotating the top plate counterclockwise until the setting notch is aligned with the spring tang (Timing Belt Tension Adjustment). Using the allen wrench to prevent the top plate from moving, torque the tensioner lock bolt to 25 N·m (220 in. lbs.). Setting notch and spring tang should remain aligned after lock nut is torqued.
Remove allen wrench and torque wrench.
NOTE: Repositioning the crankshaft to the TDC position must be done only during the CLOCKWISE rotation movement. If TDC is missed, rotate a further two revolutions until TDC is achieved. DO NOT rotate crankshaft counterclockwise as this will make verification of proper tensioner setting impossible.
Rotate the crankshaft CLOCKWISE two complete revolutions manually for seating of the belt, until the crankshaft is repositioned at the TDC position. Verify that the camshaft and crankshaft timing marks are in proper position (Crankshaft and Camshaft Timing).
Check if the spring tang is within the tolerance window (Timing Belt Tension Verification). If the spring tang is within the tolerance window, the installation process is complete and nothing further is required. If the spring tang is not within the tolerance window, repeat Steps 5 through 7.
Install engine mount support bracket (Front Timing Belt Covers).
Install upper timing belt cover. Torque fasteners to 6 N·m (50 in. lbs.)
Install the lower timing belt cover. Torque fasteners to 6 N·m (50 in. lbs.)
Install generator and bracket. Connect generator connections.
Install AC/Generator belt tensioner.
Install crankshaft damper.
Install right engine mount.
Install coolant recovery container.
Install accessory drive belts.
Install belt splash shield.
Install right front wheel.
Connect negative battery cable.
Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing.
Set camshafts timing marks so that the exhaust camshaft sprocket is a 1/2 notch below the intake camshaft sprocket (Camshaft Sprocket Alignment).
CAUTION: Ensure that the arrows on both camshaft sprockets are facing up.

Okay new here and I'm hoping someone can help...
98 Dodge Stratus, 2.4, interference engine Vin X
The timing belt broke (at a very very low speed so not worried about the valves yet). Replaced timing belt, water pump, Idler pully, plugs, wires and camshaft sensor. When I go to start it it seem to have initial spark and then runs like it's free spinning with no spark. I'm wondering if replacing the crankshaft sensor will fix this or is there something more i need to do with the timing marks? Someone said I needed to hook this up to a computer to get the timing lined up right but everything I have read doesnt say anything about that. Can someone please help me with some ideas, sugestion or anything to get this monster running? I have attached a picture of the way the timing should look and have had it spot on but still have the same issues..

Anyway, enough rambling, but remember, mine was on an 01...the second generation body style and may be slightly different than yours. And to answer your question specifically, if you have no spark, then yes crank sensor is very likely the culprit...I'd also check any fuses labeled with a "c" in the abbreviation...don't know specifically what your car will have labels of, but I have seen many such as ECC, ECM, PCM, CCI, CIM, etc...I don't know what they all stand for exactly, but the C usually stands for Computer or Controller. SO any fuse that you are unsure what it is for due to the name, check it...I have had those be culprits many many times to a no spark and/or fuel.

Head Replacement
Thanks to all of you have posted, I've learned a bunch!
I need to replace the head on my '06 SXT 2.4L. Mostly worried about timing belt replacement but a couple good posts helped with that.
I'm assuming the motor doesn't need to come all the way out. Just the right (rear) motor mount and then just tilt the motor for access? What other things need to be removed? Any special tools required? Estimate on time? Haven't done much engine work in 20 years. Any other helpful tips?
Thanks,
Fuzzy

The timing cover is extremely close to the wall. I don't see how there would be room to do anything. Also, the instructions earlier in this tread says to "install the rear engine mount".

If you take the overflow tank out, alternator off, and engine mount, it opens everything up real well...no tiliting is required. I have mine apart right now as I got it apart and belt installed, it got dark, and then I got access to my new house to remodel, so I put the car on hold...anyway, I'll get a pic when I get home from work of how open it is by removing those couple things.

Here is a pic from about the same angle as you took...Only thing in the way is heater hoses, which can be completely removed if you drain some coolant, but I was too lazy for that so I just pulled them up and down and every which way around out of my way as I needed...and you can get to everything really easily by taking the wheel off and the fender skirting or whatever off...most of the work will be done under there...just gotta be up top to get around cam sprockets.

Here is a view from almost straight underneath...it really isn't nearly as hard as it appears. Just take the entire front mount right out, there are bolts going up from under the frame. Take alternator off and stretch out of the way. AC lines can be unstrapped and flexed a bit out of the way, but DO NOT unhook them. Coolant and power steering resevoirs can be unbolted and stretched out of the way...just unhook the overflow hose from the gooseneck. Then remove crank pulley. Then take all the timing covers off and there ya go...follow the instructions posted earlier as to setting the marks correctly and everything.
