Great Replacement Thermostat!
This Stant replacment thermostat worked perfectly. Stant has always made great aftermarket automobile cooling components, so I figured I would try this thermostat. The check engine light came on in my 2005 Mazda 3 a few months back. I ran my OBDII diagnostics tester on the car, and it showed a P128 codde. This means that the car is taking too long to come up to temperature when the car first warms up in the morming. I did a little research, and it seems that eventually the thermostat malfunctions on the Mazda 3 and sticks open permanently, causing the car to take longer to warm up than it should. This also causes more pollution, since the car is running richer for a longer period of time than it should (hence the CEL). The Mazda dealer wanted $70.00 for the OEM Motorcraft thermostat and $400.00 to install it, WOW! Since I have been working on cars for years I said, "No thank you!" I ordered the thermostat from Amazon for just over 30 bucks, and replaced it in about an hour. One of the mounting bolts (there are 3) is a pain to get to, since the thermostat is at the bottom of the engine, behind the alternator. It was no problem with the right tools though. The total cost for the thermostat, antifreeze, and a couple of new hose clamps was about $50.00. No thank you dealership rip-off artists! I replaced the thermostat, flushed the cooling sytem, and reset the check engine light. The car has been running fine ever since (and no more CEL). Thank you Amazon!

LOL...
I have had this part on my shelf for a few years... When I thought I needed it, it turned out to be something else... Well that something else just happened last Sunday along with the sensor that I reviewed.. Great part, fit perfectly...access to it sucked but that is the Mazda way.. No leaks, no problems...good value for the $$ Would buy it again...

Perfect fix!
So far so good. Put her in and the temp has remained steady at operating temperature.

Works great!
This apparently works great... Or else my car might not be working and the check engine light would still be on. Pretty easy to install - beats spending to have a professional mechanic do it, and you can learn how to do it from YouTube. One recommendation though: when you take the old thermostat out, it will be full of coolant (you will basically be draining out all of your coolant. Well, it needs somewhere to go. I put a piece of tin foil underneath the thermostat (on top of the alternator) and put a cookie sheet underneath the car to catch the draining coolant. Make sure when you are finished, that you replace the coolant, start your car, then fill it up again because it will take quite a bit to fill the system. Good luck!

Great product
writing this review after reading some (-) reviews about the quality or the air bleeder valve missing both of which are wrong, this thermostat is one of the best brands on the market today. all the manufacturer specs as per vehicle applications are there, great quality, it does come with the air bleeder valve, well built and fits like a glove. would recommend buying this product to anyone who likes to maintain their own vehicle, buy with confidence knowing you will get a great thermostat.

DOES NOT FIT AS STATED
DOES NOT FIT MAZDASPEED 3 AS STATED!! The large neck that coolant flows through is about 3 inches longer than OEM and hits the A/C line.

Part works
Got Engine code P0126 on my Mazda3 (2006), so after doing some research found that it was most likely the coolant temp sensor and/or thermostat. To be safe I replaced both with this part and the "Genuine Mazda (L35G-18-840) Engine Coolant Temperature Sensor". The car works great and engine light no longer comes on. The packaging wasn't too professional... just a loose part thrown in a brown cardboard box, so I was a bit nervous about its 'authenticity'. But my mechanic didn't have any issues installing it (at least none that he thought worth mentioning), so I can't complain.
