Hello all Rx'ers', just wondering, how high does your Temp Gauge reach.
Mine reaches a bit past half..N/A 1987 Rx-7. Is that ok..??

Thanks

little high for an 87 Pete..Mine goes around 1/3.Towards Half when pushed.It's stock in the Cooling system..For now.You can always try WaterWetter in your System.(CDN Tire,about 11 Bucks a bottle).You may want to also Flush your System out and Put on/in a New thermostat and Cap(OEM ONLY).

mine goes about 170*C-180*C (when pushed hard...it goes about 200*C).
Its about a little bit more than half..on my autometer gauge.

They should run about a 1/3rd in the gauge normally. You should flush the system and change the t-stat.

But keep in mind that if we are talking about the stock gauge, it may not be accurate. They are getting old and after being rattled around for 20 years can't really be counted on for exact measurements.

1/3 is about 84 degrees on my car, while 1/2 is only 90 degrees. 1/2 is nothing to worry about but ideally the car should sit at thermostat temp (84 degrees).

A flush of the system will probably help greatly and should be done anyway.

Ok, we did the flush, added new coolant. Phoned Mazda for a new thermostat, none in stock, and only one type, none for the summer, like a 72 degree.

Is aftermarket Thermostat ok ?
What is a good Temp Gauge I can buy and install, to replace my original one.

You don't need a "summer" thermostat and a winter thermostat. Get the standard 84 degree unit. Odd that Mazda does not have any in stock but it should be a next day item.

Aftermarket thermostats don't seem to work out very well in these cars.

A "good" temp gauge is relative. Any sort of quality aftermarket electrical temp gauge will do the job. AutoMeter is the standard. Avoid mechanical gauges as they are a pain to install.

Hi Aaron, thanks...If I get a good temp gage, do I put the sensor in the same place as my original is, and cancel the orignal temp gauge in my car ??
