Mine has been chilling little to no problem so far in 20-30° PA
Sometimes going down long hills engine braking will close the thermostat and will warm up to 200, but then opens back up
I replaced it with the motorad thermostat that opens 10° lower
Motorad (SNN-2000-195) 195 thermostat for quite awhile now. Zero issues.\n\nI did try something that claimed to be a Mopar t-stat my last upgrade and it wouldnt open up until about 225 degrees. It was like 40 bucks too. So i went back to the Motorad (SNN-2000-195)
Update: replacing the MotoRad thermostat it had in it with an OEM one fixed it and it sits at 1/3rd like it should.
I narrowed it down to a bad thermostat and bad radiator. I ordered the OEM Mazda parts for $450.00
I would suggest a failsafe thermostat from Motorad and an OEM Motorcraft seal.
I had a lot of trouble this summer myself with a bad thermostat. I found a stant super stat that used to be one of the best that they don\u2019t make any anymore, but it caused me some trouble.,I had no choice I went with a motorad 195, seems to be all right It\u2019s been about four months now.
I have the ‘19 CX-5, live in NH. Seems normal to me, when it’s below zero outside and the at idle, it should not be hot. Warm after 5-10 yes, but not warm as it would be after driving for 10 minutes.
Batteries crap and so is the thermostat / heat and the trim on the steering wheel and gear shifter is thin and cheap and will come off everything else. Car is great
I just got this fixed at the dealer on my 21. Its the thermostat. They put in over a million bad ones and don't want to own it with a recall so they sent out a TSB. There's also an extended warranty for all the cars for this part/labor.
I replace thermostat even the whole block. Same issue. This fucking car don’t heat.
