Timing Belt Problem-6 cylinder Saturn wont' start

Sepentine belt broke, tensioner worn down. Replace the belt and tensioner. Engine cranks, but won't start. Mechanic says timing belt "skipped". Belt had been replaced 60 days ago. Water pump replaced 30 days ago. There is much belt debris under timing belt cover, but belt looks ok. May have debris in belt cogs. Why would this happen?

If your timing belt broke, then it is possible that the valves in your engine got bent, which won't allow the cylinders to pressurize the fuel/air mixture, and it will let all of the mix to flow freely into the intake/exhaust manifold. This can be checked with a pressure tester that is threaded into the spark plug opening. A mechanic should have one, or you can probably find one at an auto parts store.

Those 3.0 liters are very tempermental for timing belt procedure.There are multipul special tools involved.I replace these belts all the time.You can remove cover & try to rotate engine & see if timing marks align. Sometimes they can jump timing & still not bend valves but they are interference engiines & I have seen pleanty with bent valves.big job to repair.It is normal to see belt fragments to an extent but excessive amounts means trouble.hope this helps

I have a l200 saturn 03 was running with old coil and boots but was misfiring. Replaced coil and boots now wont start will roll over but wont start if does start dies within 1 min. plugged computer in says...


The 2003 Saturn L200 does have a camshaft position sensor. It is located on the bottom front of the engine behind the starter.

You will need to remove the 2-bolts that secure the starter to get to the sensor.

A p0340 fault code is indicative of either:
1.) a faulty camshaft position sensor
2.) Faulty wiring w/in CPS circuitry
3.) Faulty Ignition Control Module or Power-train Control Module
4.) or a mechanical timing fault; involving a damaged, loose, worn, stretched, or broken timing belt.

To diagnose and test the CPS and its wiring circuitry, you would take frequency measurements a designated RPMs to see if it is functioning within specifications...if the correct frequency measurements are within specs- it's not the CPS, wiring circuitry, or PCM/ICM; you're looking at a timing belt fault.

If that's the case (timing belt fault), since you have to tear down a part of the engine, it is recommended that you replace the timing belt, the timing belt tensioner, water pump, and idler pulley.

My timing belt and balancing belt broke on my 1998 mitsubishi galant es and my husband put the belts back on in time but the car won't crank. The engine turns over when cranked but won't start. ...


Are you sure it was timing belt? If so. When you crank the engine, does it turn kinda fast without making a wump wump sound? When the timing belt broke it may have done some hidden damage. Its possible it may have bent the valve stems by piston hitting them because the timing to move them was off. You need to perform a compression test on all cylinders. Borrow or rent a compression gauge from an auto parts store. They will tell you how to use it, what to look for. If compression is bad, you may have to remove the cylinder head and have a valve job done. Except that you need to replace some of the valves. This calls for some skill or at least good apptitude in mechanics. OR somthing did not go right with the timing belt install.. Thats all I can do for you now. Check the compression. Good luck.

Timing belt broke ,just replace it but it won`t crank.it sounds like electric priblem


Only the 2.3 liter diesel is an interference engine. The 2.3 Liter gas is not an interference engine. I would guess the belt was not installed correctly. The belt broke so the cam was then out of alignment with the crankshaft. Unless you aligned it correctly it will not start. BTW, the belt must be replaced every 60,000 miles. I asume you have the timing cover off, put it back on and set the crankshaft at the 0 mark on the timing cover, remove the cover and don't touch the crank. near the bottom of the cam gear is a protruding piece of plastic with three raised areas, set the cam timing mark at the first pointer, closest to the passenger side . on the back part of the timing cover is a v shaped pointer set the distributor gear mark at the pointer, remove the distributor cap and verify that the rotor is pointing at #1. Loosen both bolts on the tensioner and using a pry bar carefully pry the tensioner away from the distributor gear, tighten the small bolt on the tensioner. install the new belt starting at the crank, then the distributor gear, then the cam, then over the tensioner pulley. loosen the small bolt and the tensioner will adjust automatically. tighten the tensioner bolts and turn the engine over by hand 2 or 3 times and make sure all marks line up ( the cam mark should now be at the center pointer with the crank at 0). I find it handy to paint a reference mark for the crank inside the timing cover.

Timing belt broke on 1996 Contour; sepentine belt replaced only 3 yrs. ago - related?


Not at all. Your serpentine belt is in the same area as the timing belt, however is NOT related to the function of your timing belt.

If you have a 4 cylinder 2.0, then you have little to worry. Most of the contour 4 cylinder engines are supposed to be "non-interference"... which basically means that if the timing belt breaks, then there is not much risk of your contour's engine to have internal damage!

So... Replace the timing belt, and you should be back on the road within 1 day.

What else needs to be changed when doing a timing belt on a 1999 honda accord? and about how much should it cost?


Technically, nothing else needs to be changed when replacing a timing belt, however it is recommended or suggested to replace the timing belt tensioner and water pump while doing the belt. These items are only accessable when doing a timing belt. The cost should be under $100.00

Alternator belt replacement


Check Your Timing Belt
  • Check your owner's manual for the recommended mileage for replacing your timing belt. Replacement for Hyundai Sonatas is 60,000 miles.
  • Locate the timing belt and examine it for breaks, damage, fraying, worn spots or looseness.
  • Inspect the belt for cracked or missing teeth that may be the result of foreign material collecting between them.
  • Determine if the timing belt damage is on both sides. Single-side damage may be caused by the timing belt's guide.
    Remove Your Timing Belt

  • Disengage the negative battery cable.
  • Turn the tensioner arm to the right 14° and take the timing belt off its pulley.
  • Take out the coolant pump, idler, tensioner and crankshaft pulleys and both timing belt covers.
  • Remove the engine's mounting insulator and mount bracket and the auto tensioner.
  • Align the crankshaft's timing mark so the first cylinder piston is at "Top Dead Center" (TDC). The camshaft sprocket and cylinder head cover timing marks also should align.
  • Unfasten the timing belt.


    Replace Your Timing Belt

  • Examine the cam and crankshaft sprockets. Replace if there is excessive wear or other damage.
  • Position the new timing belt on the sprockets.
  • Relax the timing belt tensioner so it can make contact with the belt. Adjust the belt to the tension recommended in your vehicle owner's manual. Also align the timing indicators on the cam, crank and other sprockets.
  • Return the engine to the 0° mark by turning it two revolutions in the direction of travel.
  • Secure the timing belt cover and reinstall whatever was removed to access the timing cover.
  • Reconnect the negative battery cable and any other items that were disconnected.
  • Start the engine and look for leaks

How do i replace the timing belt on my '94 Plymouth acclaim?


I did it twice and if you are fairly skilled it will take 4-6 hours, if you have the V6.
Here is the steps:
1. Move car to a place that can support a jack and engine stand.
2. Disconnect battery
3. Loosen wheel lugs on passenger side front tire
4. Jack car on passenger side to lift wheel of the ground
5. Put a block under the oil pan to support the engine
6. Block car frame on left side
7. Remove left front tire
8. Remove v-belt
9. Remove idler pulley
10. Remove and support air conditioner compressor
11. Remove PS pump if you have one
12. Remove motor mount on left side and vacuum / gas connections connected to mount ( mark bolts as to locations )
13. Remove metal plate on engine ( mark bolts as before )
Tricky bolts are on the PS pump (Remove them through PS pulley holes)
14. Remove 3 plastic covers over timing belt ( mark bolts as before )
15. Note timing marks on overhead cams and crank.If none, make some.
16. Ease pressure off timing belt tensioner
17. Remove belt and replace with new. Trick here is to make sure you get the belt notches lined up. Head cams will shift when you remove the old belt. Do not tighten the belt tensioner fully or it will not perform as designed, it should be snug but be able to move.
END... replace part is backward order and drive away !!!

Timing belt


You obviously need to replace your TPS, and you may need a new belt tensioner as well. On these cars the timing belt setup is not about no 1 cylinder being top dead center. Here are the proper steps to do a timing belt on this vehicle:

To change the timing belt first place the right side of the vehicle on a jack stand and remove the right front tire. Remove the plastic cover inside the wheel well to expose the harmonic balancer. Remove the serpentine belt (standard 3/8" rachet will set in the belt tensioner to relieve tension). Remove the harmonic balancer (19mm). Place a jack under the engine on the right side of the vehicle, then remove the engine mount from the top of the fender well, (17mm deep well socket and 17mm wrench required) it is not necessary to remove the mount from the side of the engine. Remove the timing cover, (10mm) it has 2 nuts. Loosen the timing belt tensioner, (10mm) then pry it away to relieve the tension. Slide the timing belt off of the cam gear.

To position the new belt, the cam gear has a arrow on it, and the cylinder head has a small dot. Align the arrow with dot, and make sure it is aligned (the arrow must point up). The crank gear has a notch and the engine has a groove to align the notch. Again, make sure the notch and groove are aligned (they again will be up). Place the new timing belt in position around the crank gear, the water pump and belt tensioner and leave the slack at the top. Again relieve any tension from the belt tensioner, and slide the belt on to the cam gear. Place a slight bit of tension on the belt and tighten the belt tensioner. Use the 19mm bolt from the harmonic balancer and turn the engine 2 complete turns and verify that the cam gear and crank gear are in their proper positions and aligned with the dots and notches. After 2 complete turns of the engine, and verifying everything is still aligned, re-assemble in reverse. No further adjustment is necessary.

Note:There is no timing adjustment for this vehicle, and if you are not properly aligned on the cam gear and crank gear it will not run properly.

86733GH3 REPAR TIMING BELT


3.0l Mitsubishi 6 cylinder.
support engine... remove engine mount... remove alternator, power stearing pump, compressor (if equipt) do not remove hoses from power stearing pump or compressor move them out of the way were they wont get damaged. Remove the tension pulley for the serpentine belt, and the tensioner for the compressor belt if equipt. then remove the compressor mounting bracket. Next remove the engine mounting plate and the crank pulley and balancer assembly. you should now be able to remove the the 3 piece timing cover. Once removed remove the tensioner spring from the water pump and loosen the tensioner nut. Remove the belt. At this point it is also recommended to replace the water pump and plumbing as well. The water pump service life is aproximately the same as the timing belt at 60,000 miles. This engine in stock form is a non interfering type engine. Meaning that moving the cams or crank out of sync will not cause damage. Turn each of the cams over by hand and line them up with the timing mark on the top of the back cover with the marks on the pulleys. Using a wrench turn the crank so that the pulley mark lines up with the mark cast into the block. replace the belt, tensioner spring (replace tensioner if warn) and tighten the tensioner bolt. roll the crank over 2 complete turns forward and recheck the cams to make sure the marks are still lined up. roll the crank backwards and recheck the timing marks again. (this process is much easier done with the plugs removed.) If everything is still lined up correctly (crank at TDC and cam pulleys pointing to each designated mark on the covers.) reassemble the cover and assessorys in the reverse order that they were removed and reinstall the old motor mount or replace if needed.
