These fan cluthes are soon going to kill my appetite for this car. I've way too many problems with them and it was a costly endavour each time i replaced one.

Anyways, so i got this brand new one from MazdaTrix. I also got a new thermostat, just to be sure. So i went to change the thermostat and i managed to break off both bolts. Aggr. Wouldnt be a big deal, except that I managed to break an Eazy-Out inside one of the bolts. Warning: DO NOT EVER USE EAZY OUTS ON THERMOSTAT BOLTS!!! ALWAYS DRILL AND TAP.
Instead of taking 10 minutes, it took me good 4 hours before i had a working thermostat again.

I put on the new f-clutch. The car behaves good in slowmoving trafic now. However, I had read that when the engine is hot, the fan should not move freely. This is not the case with my clutch. I can move it using one finger. What the hell?

Swap to an electric fan and be happy.

my e-fan didn't do as well of a job as the stock fan. I'll only go back to e-fan if I get a Fluidyne or Koyo radiator.-Steve

how do those fan clutches work anyway? There is no electric signal going to them. Is it heat based? On mine it blows real hard for about 10-15 seconds after start up, then it becomes completely inaudible.
You might want to go E-fan if it's being that much of a bother.

Here is a good question, when was the last time the fins on the rad were cleaned and the last time it was pressure flushed?

I've got a brand new radiator.
I've got brand new hoses.
****, i must have replaced everythin on this car save for the engine.

Is it bad that the clutch doesnt "bite" when hot ??

does the car overheat? If not, then why worry?

I tested it today. Went 115 mph on the freeway and then drove in slow trafic. It didnt overheat.

Im just puzzed as to what the principle behind those clutches is...

Well, it obviously ain't broke, so don't fix it.
