Timing marks 2000 Toyota Corolla (1ZZ-FE/ 3ZZ-FE/ 4ZZ-FE/ 2ZZ-GE)

Set the Crankshaft key in 12 'o Align yellow timing chain mark
Clock position (The key aligns on the crankshaft sprocket
with the mark on the oil pump (see arrow)
body (see arrow mark)

Align the marks on the sprockets Place the crankshaft angle plate
with the yellow links of the timing with the marks B or F, facing
chain. towards you.

Double check crankshaft timing mark, on your lower timing cover has some timing marks - crankshaft should be on the 0 mark. Camshaft timing marks--intake camshaft mark set at 3 o'clock and exhaust camshaft mark set a 9 o'clock. These timing marks are critical for motor to run and start correctly. These timings marks can move while trying to install the timing belt. After, you confirm or reset timing and belt, you can confirm timing is correct by rotating the crankshaft twice. Your timing marks should be on right on timing marks discussed at the top of the page. If timing marks are off, start over with timing process.

Hope this helps. Please don't forget to rate....thanks!

Crankshaft, camshaft, and distributor timing marks-2300 cc engine (© Ford Motor Co.)

On 2000 cc engines, turn the crankshaft until the two round locating holes in the camshaft pulley are visible from the rear side of the pulley, looking forward from the left-side of the car. When these two holes are parallel to the ground, the timing pointer on the crankshaft pulley should point to TDC. If the drive belt is dislocated, the crankshaft damper will be retarded or advanced 19° per cog on the belt.

If the engine you are working on does not have the two locating holes on the rear side of the camshaft pulley, then you will have to remove the drive belt cover and observe that when the crankshaft timing marks are aligned to TDC of the compression stroke of the No. 1 cylinder, the distributor rotor is pointing to the index mark on the upper lip of the distributor housing which coincides with No. 1 spark plug tower, and the pointer on the camshaft pulley is aligned with the index mark on the cylinder head.

On 2300 cc engines, there is an access plug provided in the cam drive belt cover so that the camshaft timing can be checked without removing the drive belt cover. Remove the access plug, turn the crankshaft until the timing mark on the crankshaft damper indicates TDC, and observe that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover. Also, the rotor of the distributor must align with the No. 1 cylinder firing position.

CAUTION:

After any procedure requiring removal of the rocker arms on the 2300, each lash adjuster must be fully collapsed after assembly, then released. This must be done before the camshaft is turned.

Installation
1.Install No. 2 idler pulley (if removed). Install and tighten bolt to specification. See TORQUE SPECIFICATIONS . Ensure idler pulley is clean and rotates smoothly. 2.Install No. 1 idler pulley and tension spring (if removed). Pry No. 1 idler pulley away from timing belt area as far as possible. Temporarily tighten No. 1 idler pulley bolt. Ensure idler pulley is clean and rotates smoothly. 3.Using crankshaft pulley bolt, rotate crankshaft so timing mark on crankshaft sprocket aligns with timing mark on oil pump housing. See. This will position keyway in crankshaft sprocket at 12 o'clock position.

CAUTION:If reusing timing belt, ensure reference marks on timing belt align with reference marks placed on crankshaft and camshaft sprockets. Ensure timing belt is installed in original direction of rotation.
4.Ensure all sprockets and idler pulleys are clean.

ignition timing marks are notch on crankshaft pully and marks on timing cover, but is controled by ECU and is not adjustable,
valve timing marks are, dot on camshaft pulley and mark on cylinder head at approx 4 o'clock, crankshaft marks are dot on crankshaft pulley and dot on engine at approx 1 o'clock hpoe this helps

6. Installation
   NOTE: Ensure that the timing marks on the camshaft sprockets (6256) and the seal plate are properly aligned. Ensure that the timing marks on the crankshaft sprocket and the oil pump housing are still aligned. NOTE: A new timing chain/belt has three white timing marks that indicate the correct timing positions of the camshafts (6250) and the crankshaft (6303) . These marks will help ensure that the engine (6007) is timed properly. When the engine is properly timed each white timing mark on the timing chain/belt will be aligned with the corresponding camshaft and crankshaft timing mark on the sprocket. Because the white timing marks are not evenly spaced you will need to refer to the following illustration for proper timing chain/belt placement. There should be 40 timing belt teeth between the timing marks of the front and rear camshaft sprockets and 43 teeth between the timing mark on the front camshaft sprocket and the timing mark on the crankshaft sprocket .
   
   NOTE: Verify that the camshaft timing marks are aligned with the timing marks on the seal plate, and that the crankshaft sprocket timing mark is aligned with the timing mark on the oil pump (6600) .
   
   Install the timing chain/belt starting at the crankshaft sprocket and moving around to the camshaft sprocket following a counterclockwise path. Do not allow any slack in the timing chain/belt between the timing sprockets. After all of the timing marks are matched up with the timing chain/belt installed, slip the timing chain/belt onto the timing chain/belt tensioner .
