2004 suzuki forenza with gm motor 2.0

Engine timing is done electronically. It is based on Cylinder 1 being a few degrees before TDC (Top Dead Centre of firing stroke).

Valve Timing is set using marks when you change the timing belt or chain. That is set with Piston 1 at TDC on FIRING stroke.

Here is the firing order. It is nice and easy, 1, 2, 3, 4, left to right.

Yes, If the timing belt brakes or skips several teeth. The 2.0L Suzuki engine pistons will and do hit the valves under that condition.
You should change that belt at 100-120k miles.
You can start by R&R the timing belt and setting everything back to specs,
Do a compretion test - that will be your awnser. Low or no compretion + bent valves.
The cheepest fix is a certified used low milage motor - put your new timing belt on the used motor for good measure.

Instructions

• Disconnect the negative cable on your car battery. Make sure to wait for the engine of your Suzuki Forenza to cool off completely before you start working on it.
  
• 2Rotate the engine using a wrench attached to a crankshaft bolt. Align the timing mark on the pulley to the 0o mark on the scale.
  
• 3
  
• Remove the screws and the bolts that hold the timing cover in its place and take the cover off. Loosen the bolts that hold the spring-loaded tensioner of the timing belt a little. Pull the tensioner away from the timing belt and then tighten the bolts again.
  
• 4Pry off the timing belt from the pulley channels and the camshaft sprocket with a flat head screwdriver. Set the old timing belt aside and compare it with the new belt. The new belt should have the same width as with the old timing belt and the inside surface of both belts should have the same size of teeth.
  
• 5Put the new timing belt on the sprockets and make sure it is positioned correctly. Loosen the bolts that hold the tensioner and pull the tensioner toward the timing belt.
  
• 6Adjust the timing of the belt. Strictly follow the instructions on the Suzuki Forenza manual. When the timing is set, check if the timing marks on the can, crank and sprockets are still aligned.
  
• 7Turn the engine with the wrench on the crankshaft pulley two whole circles until you reach the 0o mark.
  
• 8Reinstall the timing cover and tighten the screws and bolts that hold the cover in its place.
  
• 9Reconnect the negative cable on your car battery. Put the key in the ignition and start the car to check if the timing belt replacement was successful and that the car is running properly.

YOU MORE LIKELY DAMAGED THE CAMSHAFT ALSO.

it might be the idler on the tension adjuster inside the timing belt cover...if so replace it soon..it is a very vital part....hope this helps
