Perfect fit for my 2010 Sonata. Confirmed that my temp gauge is faulty, and the car isn't overheating.

This seems like a good sturdy cap. It made a good seal and fit my mazda 626 perfectly. I love the idea of the thermostat as my dash gauge is not 100% accurate but i have not tested it yet.

Installed in my NB Miata and works very well. Using it to verify my cabin water temperature gauge and is very accurate. No leaks no fuss and looks great.

Might be accurate, don't know. The short temp probe is several inches away from the actual coolant level. Don't know if air temp in reservoir and actual coolant temp are the same. Would not recommend unless short temp probe would be immersed in coolant.

The factory coolant temperature sensors are known to be fairly inaccurate on these cars. (NB 99-05 Miatas). I bought this as a backup to the factory temp sensor and as a cool looking cap! looks great in the engine bay, no leaks, and works well.

I needed a new radiator cap, so I bought this one because I'm a gadget guy. It's perfect if you ever need to service your cooling system, you'll know when it's safe to open your radiator cap.And if you're chasing a overheating problem it could help you determine if it's the gauge that's faulty or ba temp sensor sending a false signal to the ECU.

So far no problems like other folks have had. Using this as a diagnostics tool for overheating while working in the engine bay. Stylish so I can leave it on the car. Functional so I can see radiator temp. Cool item. Will get one for the truck.
