You don't. The 2007 Toyota Rav4 uses a chain and not a belt.
I know of no Toyota Rav4 that came with the 3.3 Liter engine which does have a cam belt. The 3.5 was installed in the Rav4 and it has a chain.
No
The 2011 Toyota RAV4 has 16 valves.
Timing belt
The serpentine belt on a 2003 Toyota Rav4 can be loosened by turning the retaining bolt on the idler pulley. The belt can then be shifted inward to loosen.
The 2.0 liter 4 cylinder in a 1999 Toyota RAV4 has a timing BELT ( it is NOT an interference engine , replace the belt at 90,000 mile intervals )
