Toyota Repair/timing belt on 99 RAV4

Not totally true... The engine in the 1999 Rav4 is an interference engine meaning it is possible that if the belt breaks that the valves could hit the piston and cause major damage. If this it happens on an engine that is not an interference engine then there will be no damage.

Timing belts do NOT necessarily make any noise before they quit!  Also, if the belt breaks, you DO run the risk of serious engine damage -- on one hand the engine might just stop running, on the other hand, it's highly likely that when it does stop running, a cylinder could also swallow a valve, which is massive engine damage you DON'T want any part of.

Modern belts are reinforced with fiberglass fibers, so they don't stretch much at all, but the fiberglass can become brittle, so they can just snap when they're run for too many miles.  That's when your real problems start.

Get the timing belt replaced ASAP - it's just like changing oil -- essential, indispensable preventative maintenance.

The 2 liter 4 cylinder in the RAV4 (and the other 4's as well) is an interference design.  This means that the valves will hit the pistons if the belt breaks!  Get your belt changed.  Doing the water pump isn't a bad idea since it is buried behind the belt.

From everything I've seen on the 'net, the older RAV4s (and even newer ones) are non-interference engines.  They're 4 cyl, 2.0L DOHC, with engine designation 3S-FE.

know what you're talking about before answering questions buddy, the that RAV4 has an interference engine if the belt goes you can blow out a hell of a lot more than just the belt
