Timing marks setting Corolla 4A-FE.
Align the notch on the crankshaft pulley with the "0" mark on the timing belt lower cover.


With the crankshaft pulley being aligned with the 0 mark on the timing belt cover, the hole on the camshaft sprocket should exactly be in front of the notch of camshaft bracket.



Hope that works.

spark or cam ?????????????????
and which engine, some cars have up to 10 choices.
most are about 3 or 4.
not of this can i guess.

the timing marks are located on the pulleys , clean them off & then run around the pulleys with pool cue chalk, the timing marks are plainly visible after this little trick/tip.

Arrows point to timing marks in correct position.

Firstly the no.1 piston should be at TDC (compression).

The upper camshaft sprocket has a smaller hole in the web. This should be lined up exactly with the TDC timing mark behind it on the cam bearing cap. In this position it will be vertically upwards.

At the same time the notch in the crankshaft pulley timing flange should be opposite the 0 degrees mark on the timing marks on the front of the lower belt cover.

TIMING MARKS ON CAMSHAFT SPROCKET A LITTLE SMALL SQUARE MARK ON TOP BOTH GEAR SPROCKETS ON CAMSHAFTS TIMING MARKS SHOULD BE IN THE 12 OCLOCK POSITION BOTH CAMSHAFT TIMING MARKS SHOULD BE LINED UP WITH TIMING MARKS REAR OF TIMING MARKS ON TOP OF CAMSHAFT SPROCKET HOUSING. IF STILL HAVING TROUBLE WITH FINDING THE TIMING MARKS.YOU NEED A HAYNES REPAIR MANUAL.

The timing marks to use are spot-drilled on the faces of the timing gears.
The timing marks on the camshaft gears must align side-by-side, and as closest as possible on the Toyota,Camry 2.2 engine.

Belt covers need to be on. Timing mark on crankshaft (while on compression stroke) should line up with TDC mark on cover. then Camshaft mark, needs to line up by looking through access hole of cover, and align mark on cam sprocket with pointer on inside of belt cover.
