Toyota Echo

You don't. The timing chain should last the life of the engine. If you have over 300,000 miles and the engine is making odd noises like metal grinding it may be the timing chain. This information was taken from my repair manual. You shouldn't have to worry about it until the car hits the 300k mark. By then you should have got your money's worth out of the car.

6x9s in the rear deck. The doors are funny though. When you pull the door panels, you will see the front speakers (5 3/4 or some off-size like that) are mounted in some plastic brackets. This is because the window comes so close when it is down. Solution? Drill out those rivets holding it in, cut the crap out of that bracket so that is is open in the middle (formerly the speaker itself), and mount 6 1/2 speakers in them.

Have a helper pull and hold the hood release lever, then use a pry bar to lift the hood enough to get your fingers in to unlatch the release at the front of the hood.

manual recommends 5w and 10w

There is a threaded socket at the front of the car near the lower grill on the drivers side. There is a plastic cover piece over the area that can be removed by squeezing it. The large metal eye bolt in the trunk (under the carpet near the spare tire) can screw into this threaded socket. Similarly, I believe the eye bolt can screw into a socket in the lower rear of the car, which can then be used for emergency towing or to pull someone else out of something.

No

Try pulling it up hard while pushing the button in, then pushing down. If that doesn't work, perhaps something fell into the handbrake compartment and is obstructing it. You can remove the plastic shroud around the handbrake to inspect it better, instructions can be found here (scroll down half way, its part of the instructions for replacing an O2 sensor): http://www.carspace.com/guides/Toyota-Echo-How-to-change-post-catalytic-O2-Sensor This may seem like a big job, but its not bad at all.

Remove the plastic cover on top of the engine. (4 bolts) You will see 4 modules connected to electric wires on top of the engine. Those are the ignition coils. They are bolted to the valve cover with a single bolt. Remove that bolt and unplug the connector (I did one at a time) to easily remove the module from the plug. You will see the plug down the hole. Use a 5/8 Inch spark plug socket and remove carefully, engine being cold. Aluminum heads have fragile plug threads. Replace with new plug which should normally be pregapped at .043 in (for Bosch Platinum plugs the gap is .032). Tighten snugly but don't use too much force. (torque wrench at 15 ft/lb) Replace coil module and reconnect wire and you are done. Don't forget engine cover.

Note: The 2000 model echo came with special iridium spark plugs that do not have to be changed for at least 100,000 miles (I changed mine at 120,000).

Most Echo owners consider the Denso (Part #SK16R11) or NGK (Part #IFR5T11) Iridium plugs to be a good replacement for this vehicle and they can both last for 100,000+ miles.

I feel like I've answered this question at least 3 times. Look at the back of the storage compartment near the drivers left knee, there is a removable panel there, fuses are behind it. ACC fuse is 15 amps.

The fans on this car and most other modern cars are not belt driven, they are driven by electric motors which are connected to the car battery. If you meant the drive (or serpentine) belt, this question has already been asked and answered here.

Since you need to use a code reader to find out what the problem is anyway, use the code reader to turn off the light while you are at it. Not sure why anyone would want to do it another way, but you can also disconnect the negative terminal on the battery, or pull a fuse in the fuse box below the steering wheel. You might lose your radio presets doing this.

It's pretty easy. Locate the generator/alternator which is the top from pulley that the drive belt touches. On the bottom of the generator is a 12mm bolt, loosen this (but there is no need to take out off, just loosen it). There is a slider bracket on top of the generator with another bolt, loosen that one as well. I strongly recommend spraying penetrating oil (I like deep creep but there are many that will work fine) on the bolts and all along the slider area. Now that its loose you can push the generator back, taking the tension off the drive belt, now you can easily remove the belt. When you are ready to re-install, just pry the generator forward again until the belt is tight, you can use a pry bar, you really need two people for this, one to pull it back, and the other to tighten the slider bracket bolt down while the belt is tight. If you are putting on a new belt, you may want to check and re-tighten it after a break in period (couple days of driving). Don't forget to re-tighten the lower bolt on the generator after you have locked down the top bolt.

It shows you weather you have heart disease, or bad heart valves. It can also show you if their is a blockage somewhere that may lead up at a heart attack.

Why would you want to bypass it? It helps keep your car from being stolen. If there is a problem or you need a key that works with it, just fix it and/or buy the key. A more detailed answer can be found here: http://wiki.answers.com/Q/How_do_you_remove_the_immobiliser_from_a_1995_Frontera_Sport By design it is difficult and expensive to remove this feature from a car.

Just about any aftermarket cruise control package will work on a 2000 Echo. It should be professionally installed to make sure there are no safety concerns.

There are two T30 torx bolts on either side of the backside of the steering wheel that anchor the airbag to the steering column. Loosen those (they shouldn't come all the way out, just enough to get the airbag off the column). You will see three 5mm hex head screws at each of the three points of the airbag. Under those screws are the contacts for the horn, there are three separate sets, one at each point. Hitting the horn too hard can damage the contacts so they are closed all the time thus the horn sounding nonstop. Dirt and dust can clog the contacts so that they won't close at all and thus no horn. Hope this helps.

On My 2000 Echo, I was able remove the handle by taking needle-nose pliers and removing the crescent shaped pin that holds the plastic handle to the metal gear. It's difficult to see and even more difficult to remove, but after its off the handle just slips off. Good Luck.

How would I wire an EFIF control box to the computer to control the fuel mixture, so my hydrogen system works better

depends on the oil you use, recommended for mineral 5000km for synthetic 10000km

It doesn't have a timing belt to replace. Echo's have a timing chain (one of many great features for this car). The chain has no replacement interval, and should only be replaced if there is a problem (for example if it is making a lot of noise). There are two serpentine belts, one controls power steering and air conditioning, the other controls the water pump and alternator. The later one is on top, and is somewhat easy to replace yourself for just a couple of dollars. It can be inspected for wear (excessive cracking), the alternator bolt can be loosened and alternator pushed back (not removed) to change this belt. I don't know the official change interval, but I replaced mine at 150,000 miles but it was still in good condition actually. The other (lower) belt is more difficult to change on your own, and I wouldn't bother replacing it until there is a problem, as power steering and air conditioning are not critical. Never. The Toyota Echo doesn't have a timing belt. It has a timing chain which should last the life of the car.

its pretty easy. First place to look for instructions with diagram would be on the cover of new windshiled wipers that u buy. You just need to press and snap the vipers out of the long rod at the tip. pull the vipers down, inwards along the long rod.

Which bulb are you trying to change?
