How do you replace the alternator on a 1997 Mazda 626?

with a lots of patience....

2.0 I-4 or 2.5 V6?

If its the 2.5 1.put the car on ramps 2. drain radiator fluid3. remove upper radiator hose3. loosen/remove alt. drive belt (loosesn belt tensioner bolt and then move the tensioner up with adjusting bolt, a/c belt similar)4. remove plastic splash shield 5. loosen/remove drive belt for ac compressor.6. remove a/c compressor & support it on a stand but DONOT DISCONNECT A/C LINES 7. loosen alt. bolts (2) and unplug/unbolt wires from alt.8. remove old alt. from car (be careful not to damage radiator as there is not much clearance)


don't forget to refill and bleed the cooling system. you may have to unbolt the radiator supports and remove the cooling fan to gain access to the alt.

also, the 1st alt. I bought was bad, might be a good idea to have your new alt. bench tested before installation, most parts stores will do this for free.

How to you retrieve the fault code when the check engine light of a 98 Mazda 626 is on?

Since it is OBD11 it requires a scanner to retrieve the codes. Most parts stores will read then for free.

you can use a car scanner to clear it out.

How do you replace the headlight bulb located on a 1999 Mazda 626?

I followed the procedure for the 1998 model in an earlier post and it was exactly the same. Just remember to handle the new bulb by the base when installing to keep oil from fingers off of the glass. First I removed the two bolts that hold the intake in place. Then I moved the intake off to the side. Then you have to pull back the rubber hood from the light. After that I used a pair of pliers to unhook a clip that holds the bulb in the mount. Dudeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee you were right!!

For the right side you have to remove two screws and move the coolant reservoir via Phillips head screwdriver. You can reach the left side without removing anything. You will need plenty of lighting to see what you're doing.

How do you replace the dash light bulbs in a 1999 Mazda 626 LX?

To get to the dash bulbs, you have to remove the side plastic panel in between the dash and the driver door. You can pry it off, but be gentle because it is only held together with plastic pop-rivets. You will not have to replace them, but you might break one or two (no problem). Then, you can remove the panel on the top of the dash and access the light bulbs behind the display. Don't be afraid, it all comes off with pressure. Just be careful. ---------------------------------------------------------------------------------------------- In the 1997 Mazda 626, all you have to do is unscrew the instrment frame, pop it out of the plastic rivets and remove it. After that, unscrew the instrument cluster (there are four screws, two on top and two on the bottom) unhook the three electrical outlets and pull the cluster out. It's quick and easy.

How do you temporarily disable the alarm on a 98 Intrepid ES?

Just break through the window rip the wires out from under the steering wheel and cut all of them. The alarm should be temp disabled. Warning: You may get arressted. Caution: Free ride in Police Car.

You can do this by turnning your key forward, disconnect the battery cable, let it stay off for about 1 minute, hook it back up, and the alarm should be off for now and the car should start and stay started!!!

How do you fix a transmission code 1744 on a 1998 Mazda 626?

1999 Madza 626 transmission code 1744I have a 1999 Madza 626 that I bought less then a year ago with a rebuilt engine, and have had to replace the timing belt on it and now this Code 1744. It is the Torque Convertor clutch slipping. I am having the same problem and 2 different places said they had to research it. I called someone out of the phone book that I had taken a previous car to and he knew right away what it was. He said you can't feel it but it has something to do with when you go over a large hill and alitude the check engine light will come on, you can't feel it slipping but something inside is not right. You have a bad transmission, bottom line. I wouldn't mess around with it and get it fixed right away. I had another car with a bad transmission and don't want to get stuck again. Here is a link to a site that will tell you the same thing . I am taking my car in today and he said it is a 1 1/2 day job. They charge 275 to take it apart and apply that to any parts it will need. I will keep you up dated on my transmission. I suggest you find a transmission specialist in your area that can tell you right off hand what it is and you'll know he knows his stuff, anyone who says they need to research it doesn't know their transmissions.

I have a 1999 Mazda 626 with the CD4E transmission that had the engine code 1744. The transmission in my car would slip after the fluid was warm. My car had 123000 miles on it and had the transmission rebuilt once before. There are brass bushings inside this transmission that were worn out on my car. I bought a newer CD4E transmission from Ebay (40,000 miles) and put a shift kit in in with a new torque cnverter and new gaskets. The shift kit comes with drill bits to increase the size of the lub ports to increase oil flow to bushings. The previous rebuild was $1200 but obviously they did not change all the parts that needed changed or used the wrong parts. These transmissions are expensive and can be hard to find. I got one from a Ford Escape but had to use the old bell housing because the Ford Escape has a different starter mount. I was told they could not be interchanged but for me it worked.

What is engine check code P112 on a 99 Mazda 626lX V6 engine?

It is the intake air temp is low. The sensor that is in the air intake before the throttle body is probably disconnected.

The "0" in p0112 is generic. See Mazda specific codes below--look at P1112. Locate the sensor by facing engine and find a black box in front of you. The sensor is to the right of the black box and it's the second connector.

How do you change a timing belt on a 1989 Mazda 626?

Wrong car

Here's a web page that shows how to do it on a Mazda Miata, which is bound to be somewhat similar and somewhat different, but it should show you what you're in for if you attempt it:

I just did my first timing belt advice do a i did and replace the idler, tensioner, and tensioner spring while you're at it. First, remove batter power. Second remoce the plug wires. Remove the power steering pump, with the hoses still atached. Next make sure the engine is supported and remove he motor mount. emove the head and gasket. Neext the right wheel and splash guard. Remove the tension via the teniosner with a Allen wrench. put on the ne belt and reassemble.

How do you replace a speedometer cable on a 1989 Mazda 626?

The 1989 to 1991 Mazda 626 models, have a similar speedo cable setup. There are 2 kinds of cable. The first is a one-piece cable that runs from the transmission to the back of the speedo as one continuous length The second is a two-piece cable that has a 6 inch section from the transmission, connected to a 40 inch piece which goes to the dash. The care easily discernable because the two piece one has a large coupling on it, six inches from the transmission. To replace, simply slacken the nut on the cable from the transmission side first, using a 17mm open-ended spanner. Once off, pull the cable out of the tranny by leaning over it and gently punning it straight up. Then, remove the dash console by uncrewing all the screws. There are 4 to 5 screws, found on the underside of the dash, in front of the gauge cluster. Once off gently pull the finiher off exposing the gauge pod. It's an all in once pod of the gauges with a clear plexiglas cover. (Take care not to scratch it while handling it) The cluster itself is held to the dash by four screws. These are clearly visible in the four corners of the gauge pod. Once removed, pull the pod to you (sitting in the drivers seat) slowly. It is still connected via electrical connections. These must be unpluged so you have to reach behind the gauge pod using as little space as possible. Once unplugged, the final attachment is the speedo cable itself. It's connector is round and thick and either yellow or white plastic. There's a tab to one side that must be pressed to release it. Press the tab and pull the cable away from the gauges. ( Away from you/ towards the windsheild. ) Once it's out you can freely slacken any cable clips holding the speedo cable unser the hood and along the firewall. Pull the now free cable back through the firewall towards the engine. Handle the cable clips carefullyt and re-use them as they arent sold with the cable and are hard to source. Just repeat the process in the reverse for installation.

Oxygen Sensors

If a 1997 Mazda 626 engine light keeps coming on and the mechanic already changed the oxygen sensor what else could be causing this to happen?

Hi guys ( and gals)... had the same problem on a UK registered 2001 626 GSi Automatic ( not Ford Built ) at about 100k miles and took it to my main dealer with a virtually full tank of petrol ( see below) for a computer code check as the problem was intermittent..they diagnosed and fitted a new lambda sensor ( at great cost ) which seemed to cure the problem until fuel ran the warning light back!.

Noticed that when I had refueled, it was fine but when fuel was low, the light came on and the car started missing a bit..It felt almost like fuel starvation like on old motorbikes that I owned years ago but filter was clean / almost new. Will add that car was serviced "almost religiously"!!

Went to a backstreet garage nearby who diagnosed at once "fuel pump failure"...the weight of the fuel was forcing it through the system and as fuel was used, less was getting to engine, getting leaner etc, etc! Fitted ( cheaply ) pattern fuel pump, problem solved, gave the car away in 2007 with 250k miles on clock when I bought my latest Mazda 6 and it is still going strong locally!

My advice is, check fuel pump before lambda O2's easy now I know, pull the pipe off the connection block and see the flow, if you get soaked in petrol, the pump is ok ( and don't go near a naked flame!), if not, likely to be pump

Following answers are nothing to do with me but where I have probably tapped into the wrong section and posted incorrectly... please observe and respect their solutions..who knows, they are probably right and little me, in Cornwall, UK is wrong! Have the proverbial, " Nice Day "

There's no way to know until you hook up an OBD-II code scanner to read the codes. There are several scanners available on the market, the cheapest is around $122 but any decent garage should have one these days. The Mazda uses ISO 9141-2 protocol.

There's a nice list of OBD-II codes here http:/

i had the same problem.. i found a wire pulled out of the pin at the connector, not to far from the o2 sencer..

error code 0171. system to lean. today just changed fuel filter, Mazda 626 97. not sure if the error code will come back or not. will know tomorrow,

Funny, I dealt with this today, mine came on and i hooked it up to the ODBII and it read "system to lean" im assuming the fuel filter needs to be changed.

I have a 1999 Mazda 626 with a 4 cylinder that needed the intake manifold gasket replaced. I was told it was a common problem for the gasket to leak. The leak at the gasket will cause the car to run lean because of increased air. My car also had an idle problem.

I had the same problem with my 1997 626 it come to find out i had an exhust leak and i also had a trans problem. The exhaust leak made my car run real lean.But ya your best bet is to hook it up to the ODBII to get the code or codes and go from there.

If the CE light comes on, drive to your nearest Auto Zone store and they will check it and give you the codes for free.


I had a code coming back "system too lean" also a code that the O2 sensor had a problem and "catalytic converter not efficient. The engine acted like it was running out of gas and the tranny even gave me trouble and had a code on that too. Another code said I may have a dirty MAFS. They make a MAFS cleaner to spay on and clean. All the codes went away and the problems were fixed for $7 !!! Makes sense if the engine is not getting the right air combination to start with all the other sensors will pick up a bad reading. By the auto repair shop charged me $100 to diagnose this and give me the codes and concluded I needed a new cat converter at $1300 , a rebuilt tranny at $2,800 and clean the MAFS at $60

Autozone gave me the same codes for free.

Brake Pads and Rotors
Mazda 626

Chevy Avalanche

How do you change the rear brake pads on 98 Mazda 626?

Same as the front except don't try to compress the caliper. remove the cap that is in back and loosen with an Allen wrench

  • After you've installed the pads and put the caliper back on, retighten that screw in the back of the caliper with the Allen wrench until it is tight again, then back it off a quarter turn. This is to readjust the brakes. If you don;t do this the brakes will be really mushy.
AddendumThere is no Allen key or bolt to undo (unlike a Saab 9000). Instead, when the pads have been removed, you need to turn the caliper piston to retract it.Use a pair of pliers direct on the piston and turn clockwise to retract. This works!

How can you remove and replace the short water hose located just beneath the air filter on a 1997 626 Mazda?

you cut the old hose off. size up new regular heater hose to match same length.push new hose as far as you can on the right side then bend the hose to push over the left side. make sure you put the hose clamps on before you start to put the new hose on.make sure both sides are about equal then tighten the clamps down. good luck!

Distributors and Distributor Caps
Starters and Ignition Systems
Ford Probe
Mazda 626

What could cause a 1994 Ford Probe GT that has a new distributor still have no spark?

okay ! I have posted that it probly is the crank postioning sensor ford still makes things seem way more diffacult than they really are you cant find any specs for anything to make sure the part is bad or not one of the reason that ford is headed for the scrap pileIn my 94 Probe GT, I could get no spark out of my car, and found out that it was the distributor. Word of advise...spend the extra $ and let someone else put it on for you. I did mine myself twice, and both times, the seals came loose and water got in, causeing the motor to rev up and down while driving, and then cutting off at 2500 RPM. It was not good!

my recomendation is pull distributer cap and turn over the engine look to see that your rotor button is spinning, if its not spinning check you timing belt, but if it is spinning check on replacement of your coil pack and/or your entire distributer once all else fails...

My Timing belt is brand new and it is in perfect time...


I bought the car after it had set for a year or so, put on new timing belt and water pump, car ran great for two days then suddenly when I hit 4500rpm my tach flip out and the car died. I checked for spark and got nothing. I double checked timingbelt, replaced the Crankshaft position sensor and the distributor.......I'm Lost

Have you tried resetting the Fuel Pump Cut Off switch in the left rear corner of your trunk? Is the "Fuel Cut-Off" lamp illumated on the dash when you try to start? This is a perplexing problem...seems like as the cars age and the distributors begin to wear down they send to much current to the immobilizer units in the cars(these trip the Fuel Cut-off Switch in the trunk). The excess current evidently erode or overheats the soldering on the chip board of the immobilizer unit, thus, triggering the fuel cut-off switch to activate.

All of that happening has eventually caused my probe to fail to start at all now...the fuel pump is not pumping and there is no spark being sent to the plugs...all a result of the immobilizer believing it has a problem.

The one other item it can be is a DOCUMENTED problem in Ford's Technical Service Bulletins where Ford admits there is a problem with corrosion on the wires for the immobilizer & fuel cut-off switch link.

I am in the middle of trying to fix mine. Good luck.


Hey buddy Why don,t u check your fuses take a ohm meter Check the resistance of Primary Wire or secondary wire. If there is no current in the primary wire that means there is problem with your Iginition relay change your relay u don,t need to reset your fuel system just change your relay that u can find when you wil pop the hood it should be green color. I think in Canadian it would cost u 106 try that hit me back

Ok I would say do a paperclip diagnostic on it it will throw you codes to check my probe threw me the code for my crank shaft postioning sensor and also could be the distributor could have a bad ignition module on it if the 94 is the same as the 93 which i think it is moisture gets in from teperature changes hot to cold ect... use a paperclip from your ten pin to your ground pin on your diagnostic block located by your battery hope this could help ive been thru it all with mine and found myself turning in distributor after distributor on warranty to fix my problem im still looking to find out if there is anyway to prevent the moisture from getting into the distributor

Fuel Filters
Mazda 626

Where is the fuel filter located on a 1998 Mazda 626 LX?

The fuel filter is attached to a bracket located on the drivers side of the engine compartment. Look down in the space between the master cylinder fluid reservoir and the rear of the air filter compartment, you will be looking at the top of the fuel filter cannister. It's hard to get at. You will have to take off the air filter box. Go to
