Mazda 626 Engine Questions



  • I recently purchased a 1989 Mazda 626 from a friend. It needs a new alternator. I haven't been under the hood, so I don't know the engine layout yet. How difficult is it to change and where on the engine is it located?
  • I have a 1993 626 and it chews up the water pump/alternator belt often. The crank pulley is out of alignment with the alternator & water pump. This is a two piece crank pulley that has an outer ring the belts ride in attached to an inner hub that fits on the crank shaft. The outer ring has moved foward about 1/4", I can't get the bolt off the pulley because the crank shaft turns when I try to loosen it. How do I get the bolt off? Please help!!
  • I have a 1998 Madza 626 ES,2.5,with a V-6, I had the same type of sound on my Madza, I researched and found the timing belt can make this type of sound. Took it to a repair shop and that is what that sound was, like a clicking sound. I had thought is was internal and serious, in a way it was it had cost me $800 a lot of other parts were needed. I is suppose to be done aprox 60000 miles

    I have a 1995 Mazda 626 that the alternator belt makes a squeeling sound and eventually breaks. I'm told the pulley is out of alignment and it has been re-aligned. After a month or so, the squeeling starts and the same thing happens over and over. I've done some research and found that I need a new pulley. Does anyone know anything about this ???? Need to get this problem fixed once and for all.

    Did changing the pulley solve your problem of the belts getting chewed up ??? I'm having the same problem and keep bringing it back to the mechanic but it ends never getting resolved. Please let me know.

    Has anyone replaced a crank pulley? I have a 2002 Mazda 626, the outer ring of the crank pulley fell off.

    My crank pulley apart off three times. Each time, I got a replacement from the junk yard. It turns out that the AC compressor was locking up. I didn't know this until the third time it the pulley fell apart The compressor had locked up completely and wouldn't turn at all. After I replace the compressor I had no more problems with the Crank Pulley.

    Mazda uses failure prone clutch master cylinders (not slave cylinders). It is the internal seals that fail inside the cylinder, making complete clutch release impossible. The clutch master cylinder is located right behind the clutch pedal and it is visible on the firewall from the inside of the engine compartment. I went through about three of these master cylinders on my car. Also, there is a flexible rubber hose, just like a brake hose int he clutch hydraulic circuit, between the clutch master cylinder and slave cylinder. This hose burst on my car and left me stranded. It is advisable to replace it if the car is more than 10 years old or has more than 100k miles.
