Toyota RAV4 Engine >> CAMSHAFT TIMING
Camshaft Timing On
Toyota 1.6L DOHC 4AF and 4AFE Engines
Timing the camshafts on 1.6L DOHC Toyota engines can be a source of frustration. This popular DOHC, 16 valve engine is used in Corollas and Celicas
The cause of the frustration is two sets of timing marks on each of the integral camshaft gears (Figure 1). Each set of marks has a particular purpose. One set is used to time the intake with the exhaust camshaft when they are mounted to the cylinder head. The other set indicates the TDC (Top Dead Center) for both
Mount the camshafts to the cylinder head using the following steps:
1) Install the exhaust camshaft and torque the bearing caps in sequence to
108 in.lbs. (Figure 2).
2) Rotate the exhaust camshaft to position the knock pin slightly past
9 o'clock (Figure 3).
3) Mount the intake camshaft, aligning the installation timing marks and torque
the bearing caps in sequence to 108 in.lbs.
4) Rotate the camshafts to ensure alignment of the timing marks.
5) Finish by aligning the TDC timing marks (Figure 1).
The cylinder head is ready for installation on the cylinder block. Align the crankshaft and camshaft sprockets before positioning the timing belt (Figure 4). Aligning the through hole in the camshaft sprocket with the mark on the camshaft
bearing cap is the only tricky part.
