when you replace your thermostat do you have to replace it with an oem one and by oem do you mean one from napa i heard that aftermarket thermostats are no good and you must use a oem mazda one but but stock mazda one do you think the napa one would work.

 

Basicaly most people use the OEM one ( from Mazda) Because they are more dependable then any other ones that other manufacters make... PLus the Mazda Oem thermostat has a pin on outer rim to lets any excess bubbles pass though..

you can easily get them at the dealer or at rx7.com

 

I just replaced my t-stat and I used the OEM one. Directions said to install with the jiggle pin upward. I was wondering, what the hell is a jiggle pin? Thanks for the info 06fc3s!

 

Its to allow pressure/air across the t-stat.

 

I'd stick with OEM Mazda for stuff like oil filters, fuel filters, thermostats, etc.
