Top 10 1999 Toyota RAV4 Questions & Answers

Had the same problem on my brothers Rav4. We changed the Plug wires and the problem is corrected. He had changed the plugs a couple of months ago. We had the code read at Advance Auto, it came up P0300 Random misfire. His old wires looked fine also.

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

The air fuel ratio sensor is located in the exhaust manifold before the convertor. It looks like a o2 sensor.

It means that the egr valve is working, the problem is a very common one, it's the egr modulator valve and to some extent the vacuum switching valve(VSV) for the egr valve, the modulator is attached to the egr valve, remove it and if air can pass from the bottom port through it is defective, in that case replace it and see if it takes care of the problem, if the valve is ok the egr
vsv should be replaced.

Follow the lower radiator hose to where it attaches to the engine. Remove the clamp from the hose. Remove the 2 screws that hold the small black cover in place. The thermostat is under that cover.

Sometimes the belt last forever, sometimes not. It is a tough job and expensive one as well. You should take a look at it before buying another. You need to remove one of the covers to the timing belt and look at the belt. It should only have a screw or maybe two. It is easy to get to the front one. Make sure the belt is not cracked and there is not any teeth missing. As far as miles, maybe 100,000-120,000. It is recommended to change before that but they usually last longer. If money is not a problem and you are over that, get it changed. If it does break, you are stranded and it may cause additional engine damage.

these cars have whats called a ribbon that carries any signals from the steering wheel, like cruise controls air bag and horn they can be pretty spendy get one from the dealer to ensure the correct part.
