you guys rock, this is the most straight forward explanation of this process yet, may be good to sticky it some where, thanks again

I searched and I must be missing something because I went ten pages in and could not find anything concise that was helpful at all, I am not getting a check engine light, I am not sure whether I will get anything at all with Obd1 unless I have a cel, is that correct?

I need an obd1 compliant code reader for my 92 mazda mx-3, 4cyl. I see several for sale that are advertised for fords, will these work? I am not sure if I just need one that is obd1 compliant or do I need a special one? Help, thanks

Well, I pulled the plugs and they were white so I changed the O2 sensor, I checked the cap and rotor and the contactor on the rotor was loose so I replaced that, still no joy, it gets about 3/4 of the way up on the gauge and holds now instead of going almost to H, I purged air for a really long time...

Alot of work, but imagine how quick this would be at the 1/8 mile, you could problably win all the money you put in it back at the track....

This is something I know about, I burned the copresor out of the mazda about 6 years ago, I got a junk yeard compresor, flushed it with AC cleaner and refilled with Ester oil, then I back flushed the sytem with AC clenaer driven by compressed air, then changed all the seals with neoprene, then I pul...

Check your fuel lines al the way to your engine, smell could be carrying back, also you can remove your back seat and check the seals and lines on the tip of the gas tank.

If it smells like fresh gas and your not blowing smoke, it probably is

Autozone has the thermosensor, I just got one the other day, don't know what the first line is though,

I tested the fans and they are working correctly, thermostate is opening, ie upper hose is cold and then gets hot as lower, it just seems to be generating a lot of heat, it will overheat standing still now if i hold it revd to 3000 for about 5 to 7 minutes, I am starting to wonder about the oil pump...

I changed radiator cap in addition to all the above and still overheating, the only thing I haven't done is fan relay? I noticed when looking up the fan relay that there is a fan thermostate listed, could that be a problem?

I have flushed it senseless, coolant wise, I have never run anything but sythetic oil in it, I am starting to think it may be running too lean? I am not sure what you mean by your fan comes on and your engine overheats? My problem only occurs on the highway and then only under stress, like a really ...

Well, it is better, but still overheating up hill at 65 to 70 miles in hour, to recap, I replaced above parts, and purged air out of radiator, I thought it was working, but still runs hot when running uphill at highway speeds for long distances, ie, when engine under long periods of stress This is n...

Runs like a bat out of hell other than overheating, I was worried maybe oil pump failing, I will try to purge air and see what happens, thanks

ok, i put it in with the spring part inside the motor, and the jiggler valve up, is that right?

Please read last post, thanks Car is 92, radiator replaced in 04, overheats at highway speeds, does not around town. I replaced water pump and thermostat, still overheats, gets about 3/4 of the way up the dial, does not peg out to H. It does better with A/C off, but still does not run where it is su...
