Remove the air intake that is on top of the radiator with a 10mm socket then the large hose that goes to the engine is where the thermostat is housed. Unscrew those two bolts which are 12mm and pull out the old thermostat and rubber o ring gasket. Make sure you put the gasket on the new thermostat good and line it up then reverse the last steps til its back together

P1250 and P1569 codes. Engine still running rough after complete tuneup. What should I check now. Any Mcguyver fixes? 2002 Mazda Protege5

1250 is the fuel pressure regulator and 1569 is variable timing control solenoid. Both will cause rough running. I would check the regulator out first.

2002 Mazda Protege5. While changing rear struts, the rear seatbelts had to be unmounted. I allowed the seatbelt to retract and now it will not extend (only retracts/takes in) far enough to mount it back....

Hi, these retractors or sensitive to direction so that if the are not sitting properly they will not release. as if in a roll over situation. try holding the retractor at the angle at which it was mounted and then apply slight tension on the belt pulling out. Don't take the plastic covers off or the spring inside will come a part and you will be buying new belt assembly's

Rear view mirror

Has the mirror previously been capable of providing a view of the left lane?
If it did not, the "clicking" sound is simply an indicator informing the user that the angle limit has been reached, the mirror will not travel any further.
Simply purchase a pair of stick on Convex mirrors, they are about 1.5" in diameter,they do the job perfectly. I know this because I've got them on my Protege5 mirrors.

My mazda protege5 power windows not working except the driver side. I check the fuse box #12, it is not shorted. What advise could you give me would be appreciated.

There is a safety disabling switch on the control POD on your drivers side door panel. Simply press and release a few times and observe the behaviour of the switch. It is a push for "ON" and push for "OFF" type switch, it has a marking of a square with an X across it. This button should remain down for ALL the windows to function, if you should see that it is in the up position, the 3 door windows will not operate.

Oil inside the #2 cylinder in a 2002 protege5

This could be caused by either: 1. Scratches in the cylinder wall, between the piston rings and wall. 2. A worn valve guide and seal. Add a can of Restore Engine Restorer 6 cylinder formula directly into your engine oil now, then add another in with your next oil change. This may very well solve the problem depending on severity.

Engine light on 2002 mazda protege is on even after changing o2

Try cleaning the Mass Airflow (MAF) Sensor. My 2002 Protege check engine light came on and it started stalling at stoplights if I didn't keep the engine revved a little. Manager at AutoZone checked the computer code for the light (P0171?), and it said it was running lean. He suggested I try the MAF sensor cleaner they have ($6.99) rather than replacing the 02 sensor, etc.; it made a *significant* difference. (I think I need to do it again to get it totally cleaned out, but the can is for at least 4 cleanings.) The MAF sensor is the large component that air goes through right after the air filter. If you don't have the repair manual for the car (search online for PDF's), you search for the part online to see what it looks like. Mainly, it's a tube about 4" across with some small wire things inside. The cleaner can said it was a 10 minute job; mine took 20 minutes, but only because the tube leading from the MAF sensor to whatever is next (a kind of bent elbow tube, with a couple of accordian-style ripples) tore, and I had to duct-tape that up to seal it. (Still haven't gotten that replaced - found them online for ~$40. Maybe this weekend...)

I would always replace the gasket when changing a thermostat. Old gaskets usually get damaged during removal and they're cheap anyway.
