Hi all,

Does anyone know if the 'two - stage themostat' is really required for the 89 mx-6? My local Autozone and NAPA both have the single valve part in their computers - when I show 'em my old one - all I get is bewildered looks.

1) Can I use one of these single types?
2) If not, where do you get a two-state?

Thanks!

-Martin

the dual stage is only available at the dealer. It costs $27 (themostat and gasket) with tax.

The singles will work it seems (my wrecked car did) however the car will never get up to the proper temperature. The guage will show that the engine is only halfway warmed up (when the engine is warmed all the way, the guage needle should be centered).

I warped a head from my car getting too hot. I never even knew. I don't know that it was because of the single stage thermostat, but, I'm not taking any chances. I'd go ahead and cough up the extra if I were you. Mazda used that kind for a reason. I don't know what the reason is, but, I know those guys are smarter than me.

You need one. That means your engine oil is not getting to proper temperature, and your engine is wearing prematurely.

I have a single stage thermostat and it works - but hurddawg is right because my gauge shows a lower temperature now and never gets up to where full temp used to be.
