OEM Mazda Thermostat issues
Just bought my FD and I am going to upgrade my Radiator so I decided to replace the thermostat as well. I am going to stay with the stock temp 180F,so I want to go with the OEM Mazda thermostat 8AF615171, my question is about the recent quality of the OEM thermostats. I've seen a lot of threads saying they went to shit in quality and don't even come with the jiggle pin anymore, but these threads are dated around 2007-2014. I'm hoping to get feedback from someone that has bought and used an OEM Thermostat recently and if they're good now or if I should go with something else?
I've seen quite a few threads about this; here is one thread I saved discussing the Jiggle pin issue and quality issues: https://www.rx7club.com/3rd-generati...jiggle-642855/ Thanks in advance! |
I haven't done one in a while so I'm not sure what the current thermostat looks like. If it doesn't have a jiggle pin you can drill a small hole at the top of the thermostat lip where the jiggle pin should be, that helps.
The hole/jiggle pin should be installed at the 12 o'clock position. I have been burned by aftermarket thermostats more than once, Mazda is still the way to go unless someone finds a better alternative. Dale |
I've had good results with Motorad 322-180.

I bought 5 of these,just in case they go obsolete.There were 15 left in the Toronto warehouse this morning.Note you have to buy the O-ring separately.
The quality of construction looks better than the -9U product(even if the quality of the pics is worse!) My eyeball tells me that the opening maybe larger too. |

What was your reason for going with this Motorad over the OEM one? Was it because of the jiggle pin, cost or availability? The price difference is only about 10$ in my case so cost is not a deciding factor for me.

I've seen a few oem ones fail prematurely over the past few years. Lots of fdAh parts seem to be new old stock so who knows how long they have been sitting.

IRPerformance thank you for websites

I've read the OEM thermostat opens at 180 F, if that's the case, can the Pettit be used as an OEM alternative?
Thermostat 180° F |
FWIW, I think Atkins carries the Motorad. Just changed mine about a month ago after the gasket/'O' ring failure caused a small leak. Was getting something else from Atkins and ordered a new T-stat/'O' ring at the same time. It had the jiggle-pin. Just clean the seat for the 'O' ring seal really well. There was a little crud build-up on mine, possibly from the bad 'O' ring.
