Engine Mechanical problem
2000 Toyota Corolla 4 cyl Front Wheel Drive Manual 124000 miles

Hi I had a strong slapping noise coming from the timing chain, so I took off the tensioner and the timing cover. Chain was loose(even b4 taking off tensioner), and I can move the tensioner pretty easily. Sounds like I needs the chain and the tensioner to be safe, but could you tell me how to re-time it, as far as the marks on the cams/crank/chain. Thanx.

Remove or disconnect the following:

Negative battery cable

Right engine cover

Accessory drive belt and generator

Power steering pump, without disconnecting the hoses

Right engine mount

Cylinder head cover

Turn the crankshaft so the No. 1 piston is at TDC on the compression stroke

Crankshaft pulley

Crankshaft position sensor from the timing chain cover

Accessory drive belt tensioner

Right engine mounting bracket

Chain tensioner

Water pump

Timing chain cover

Crankshaft angle sensor plate

Timing chain tensioner slipper

Timing chain and crankshaft timing sprocket

To install:

Crankshaft sprocket with timing chain. Be sure to align the No. 1 mark link with the mark on the sprocket


Timing chain on the camshaft sprockets. Align the Nos. 53 and 67 mark links with the marks on the camshaft sprockets


Chain tensioner slipper. Bolt: 14 ft. lbs. (18.5 Nm).

Crankshaft angle sensor plate

New seal in the front cover

Silicone sealant to the timing chain cover as illustrated

Timing chain cover

Water pump. Tighten the bolts marked -C- to 80 inch lbs. (9 Nm) and tighten the remaining bolts to 14 ft. lbs. (18.5 Nm). Be sure to install the bolts in their original locations. Bolt lengths:

1. A: 1.77 in. (45mm)

2. B: 1.38 in. (35mm)

3. C: 1.18 in. (30mm)

Release the ratchet pawl and compress the chain tensioner. Place the hook on the pin to keep the tensioner compressed.


# Install the tensioner, using a new O-ring. Torque the bolts to 80 inch lbs. (9 Nm).

# Turn the crankshaft counterclockwise and remove the hook from the pin. Turn the crankshaft clockwise and be sure the slipper is pushed by the plunger.

# Check the valve timing by turning the crankshaft clockwise until the mark of the pulley is aligned with the mark on the timing chain cover. The marks on the camshaft sprockets should be facing each other as shown.

# Install or connect the following:

Silicone sealant to the 2 areas where the timing chain cover meets the cylinder head.

Cylinder head cover. Bolts with washers in the sequence shown: 80 inch lbs. (9 Nm). Bolts without washers: 96 inch lbs. (11 Nm).

Right engine mount. Bolts: Marked A : 47 ft. lbs. (64 Nm). Marked B : 19 ft. lbs. (26 Nm). Nut: 38 ft. lbs. (52 Nm).
