Normal engine temp indication

[edbelton]

What is a normal reading on the temp gauge? When "normal" operating temp is reached, it fluctuates between the right side of the 8 and the middle of the zero (when on stop and go traffic). I have own other watercooled cars and the temp gauge wouldnt fluctuate once the normal operating temp was reached. Any issues here? thanks.

First of all, be aware that the dash gauge is grossly inaccurate as well as non-linear. With an OEM thermostat that begins to open at around 185F, if the dash is showing around “180”, the engine is actually around 210F, or higher………

thanks JFP, all I was wondering whether it is normal to have the temp gauge swing from between the 8 and the zero (normal temp at normal driving) to passing the half of the zero, at stop and go conditions. Once normal cruise it resumed, it goes back to the original indication, which is between the eight and the zero, straight up. Dont know what temp that is, the gauge is rather fancy than accurate when it comes to readings, all I need to know if that is considered normal. I live in South Florica, and it gets warm, plus traffic here is rather a constant issue. Thanks again.

I have never seen my temperature gauge move abnormally. It is always at about 190 when warm. The fans come on if it gets warmer. See Short Video of Normal Temperature Display when Engine is Warm

It doesn’t move abnormally, it is just ridiculously inaccurate…………..

Could not download the video, but this ia what I get, will yours go to the traffic marking? thanks.

Yes. Your "Traffic" is when the side fans should be kicking in. However, it takes a fairly hot day and a few traffic lights for the temp to rise from from "No Traffic" to "Traffic".

Note: Agree that it may be inaccurate. I think I misread the original question.

That's completely normal and fine for your engine to be in that range.
