Looking 4 cam timing and belt diagram 97 cadaillac catera

Do you mean the serpentine engine belt that is on the outside or the timing chain within the engine case?, if it is outside, you should see a belt diagram on the engine crossmember, near the radiator, showing you how the belt is routed on the pulleys, also there should be a spring loaded pulley that keeps tension of the belt automatically, no adjusting of the belt, it will adjust the tension as needed, makes it easy, just pay attention to how it is routed, if you can't find a diagram sticker under the hood, then draw your own before you get it removed, also use a long pry bar to get the spring loaded pulley to work in you favor, good luck Rick

the 97 Mitsubishi 3.5 v-6 engine is an interference engine, so if the belt broke while running it has damaged valves.

Hi, there should be marks on the belt itslf that align with hatch marks on the timing gears. Below are the instructions for installation. From these, you should be able to verify that the belt is in time. There are also some diagrams here: http://www.2carpros.com/diagrams/cadillac/catera/1997


To install:

1. Install the timing belt.
   1. Start at the crankshaft pulley.
   2. Install the timing belt with a double dash (TDC) mark on the belt aligned with the marks on the oil pump and belt drive gear.
   3. Pinch the belt with special tool J 42069-30 to prevent the splines from jumping.
   
   
2. Route the timing belt through the idler pulley for camshafts 3 & 4 then route the timing belt through the camshaft gears 3 & 4.
   1. Ensure the dash marks on the timing belt align with marks on the camshaft gears and the notches on the rear timing belt cover.
   2. If necessary, loosen timing belt idler pulley or move the cam gears slightly, with J 42069-1 and 2 still in place, until the timing belt can be installed.
   3. Tighten the idler pulley locking bolt until snug. The idler pulley bolt will be tightened to specifications after the final adjustments are made.
   
   

NOTE Timing belt deflection between the camshaft gears number 4 and the idler pulley for camshafts 3 & 4, must be no more than 0.4 inch (1 CM.).

1. If necessary, adjust the timing belt deflection by turning the timing bolt idler pulley eccentric, for camshafts 3 & 4, counter-clockwise with the special tool J 42069-40, or equivalent.

1. Route the timing belt through the timing belt idler pulley for camshafts 1 & 2 then route the timing belt through camshaft gears 1 & 2.
   1. Ensure the dash marks on the timing belt align with the marks on the camshaft gears and the notches on the rear timing belt cover.
   2. If necessary, loosen the timing belt idler pulley or move the cam gear slightly, with J 42069-1 and 2 still in place, until the timing belt can be installed.
   3. Apply sufficient tension to the timing belt to prevent it from slipping off the gears by turning the timing belt idler pulley eccentric for camshafts 1 & 2 counter-clockwise with special tool J 42069-40 or equivalent.
   4. Tighten the idler pulley locking bolt until snug. Idler pulley bolt will be tightened to specifications after final adjustments are made.
   
   
2. Route the timing belt through the timing belt tensioner.
3. Apply initial tension to the timing belt by turning tensioner eccentric counter-clockwise, with a 5 mm hex wrench, until marks are set.
   1. Tighten the belt tensioner-locking nut to 15 ft. lbs. (20 Nm).
   
   
4. Adjust the timing belt.
   1. The timing belt must be properly adjusted or engine damage may occur. Do not continue with the engine assembly procedure until the timing belt is properly adjusted.
   
   
5. Install the timing belt cover. Tighten the timing belt cover bolts to 71 inch lbs. (8 Nm).
6. Install the power steering pump pulley and bolts. Install the water pump pulley and bolts.
   1. Tighten the power steering pump pulley bolts and the water pump pulley bolts after the serpentine drive belt is installed.

Timing belt tensioner pulley; if it fails, notorious on the 97, 98, it will send the engine to heaven. Was a recall but probably well out of date now.

If you are lucky, its the accessory belt idler.

Remove the hood bracket bar, 4bolts, then the fan shroud assembly, then the belts, belt adjuster, and timing covers, line up the cam gears, crank gear to the marks , cam has 1 dot, they line up to timing housing 2 dots, (single dot to middle of the 2 dots), crank has 1 dot to mark on the oil pump housing to your right of crank gear, thats TDC. now remove the timing belt tensioner, 2 bolts, and remove the belt, if the pump has leaked, replace the belt, and tensioner if it is NOT metal Pulley, the fibre one will break down from the antifreeze. its a good idea to replace the water pump housing orings behind it, ac bracket has to come off, as the right cam on engine, this not a retiming iussue with the gear. GOOD LUCK. RDJRP

There is a special tool kit which aligns the belt on the Cateras. It's pricey but I believe there are people who rent them out. It can be done without it, but if you already removed the original belt, it's too late. The kit locks the cams in place so you re and re the belt without disturbing the timing.

Hello markcarey204: Here is the diagram you was requesting. Please rate the quality of the answer. This helps us to know it was the right information. Should you need more help please just ask. Thank You for auing FixYa. Roger

Forgot to say its a 2.4L motor.
