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 2011 Toyota RAV4 has an inline 4 engine.
The 2011 Toyota RAV4 has a 4-speed automatic.
The 2011 Toyota RAV4 is a gas-powered vehicle.
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 )
The '99 Toyota Rav4 2-door has a timing belt, not a timing chain.
