I need a diagram for the how to time on the cam sprockets on a saturn ls1 2000

This is for 2.2L engine.








Sorry for double post on cam sprockets. The timing chain has three distinct colored links, The two links with same color are for camshaft sprockets, intake and exhaust. The one single link color is for crank shaft. Good luck. You can see the marks on sprockets.

Timing mark on the cam sprocket is on the web between two of the holes. The timing mark on the crank sprocket is a small dot on the tip of one tooth. If you cannot find it make sure the sprocket isn't on backwards. These points will line up with the tabs on the tensioner AND be straight across from each other. Make SURE the tensioner is compressed while you are installing the chain. You push in on the spring and put a pin/nail through the hole to hold it in place.

you have to set your #1 piston at TDC and found the marking of crankshaft at 12 O'clock. then the camshaft at 3 O'clock. make sure the markings are in corresponding marks of each sprockets.


this diagram is a sample timing mark of a galant.

Hello tazzie13101,

Below is an image showing the timing marks. I circled the detail for the hole in the cam sprocket, you will look through the hole to aline the mark for the cam.



I hope this helps.

P0340 - Cam Timing

SYMPTOMS/CONDITIONS
of a mistimed camshaft system (all must apply):

1. Camshafts have previously been removed from the engine.
2. Engine runs rough.
3. Vehicle sets P0340 (camshaft sensor code).
4. Camshaft sensor has been checked with a known, properly operating camshaft sensor.

CORRECT:
The diagram in the manuals should show the timing marks on both cam gears to be on the blue timing chain links.

The 2.2 liter engine uses colored links on the timing chain to align with the marks on the gears. You just have to rotate the engine to where the copper chain link is up on the upper right side of the intake can gear--aligned to the INT diamond on the gear. Then the silver link should be down at about 5 O-Clock on the crankshaft timing mark. The other silver link should then be aligned to the mark on the exhaust cam sprocket. See picture below.

For the 3.0 liter engine, there are marks on the belt that line up with marks on the gears. The book calls out special tools to hold the cam sprockets in alignment while the belt is put on. There is also a special tool to lock the belt onto the crankshaft sprocket. See pictures below.
Please let me know if you have questions.

Camshaft locking tools





Crankshaft belt tool




Properly adjusted tensioner

During most engine rebuilds, a completely new timing assembly should be installed. If wear exists on any component, replacement of the entire assembly is necessary. Wear in the chain, gears, or sprockets means a timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in their correct positions. Before installing a new chain, soak it in oil.
OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing the cover on some OHC engines that have timing chains is more difficult, because the cover often fits between the oil pan and the cylinder head. There are special procedures for replacing cam timing components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling engines to check for bent valves, so that an accurate repair estimate can be made.
OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another. NOTE THIS IS FOR 2WD 4.0

THE MARKS SHOULD BE MARKED AT THE OUTTER SURFACE OF THE CAM SPROCKETS THERES 4 TOTAL ON THE CAMS AND TWO ON THE CRANK. GOOD LUCK THIS PICTURE IS RIGHT OUT OF MY TIMING MARK BOOK......2

the cam shaft sprockets have marks on them that say" front" and have a hole,, the marks should be up and level on the cams,one cam says in on it and thats intake and one says ex on it and thats exhaust cam,,,the sprockets on the cams have a little cirlce at one of the teeth on each cam these face up,,and line up with the different color links on the timming chain,,,the crank sprocket only goes on one way due to the keyway the the key way faces at the 12 clock position and you will see a mark at the same 12 position on the engine block,, there is also a different colored link for the timing mark on the cranksprocket ,actually its two colored links in a row and they go at the 6 clock position on the crank,,,then put the guides on and the tensioner and set the tension

This is a pretty tough timing belt job to do if you have never done one before. There is also a kit of tools that are essential to getting the timing right on this engine. The cams are numbered 1-2-3-4 from left to right if you are facing the cam sprockets. If the tensioner was broken and the engine came out of time you are probably looking at at least a few bent valves. Could be time well spent to perform a leakdown test before you spend too much time on installing a timing belt.
