Testing actual water temp

[Paulprior]

So is it possible to put a sender in the preferred rover position that has the characteristics of the TVR one?, if not do I use the rover gauge to read the actual temp and learn the difference between that and the gauge? But then it's also stated that the sender is in a flow dead spot and therefore inconsistent, this is all getting a bit confusing knowing which way to go, I had kind of thought reading the water temp was going to be straightforward?

I believe that the thread is different and adding a conversion unit puts the sensor in a dead spot so you're back to square one.

I think you're kidding yourself if you think these gauges can read accurately and more to the point in a repeatable way. The reallity is that coolant will be at different temperatures depending where you measure it, after all isn't that the purpose of the coolant system.

If the gauge is reasonably similar to the ECU measurement at normal running temperature, it rises as the coolant heats up and it climbs over 120 when you suffer overheating, what more information do you think you can get from it. A resistor of 160ohms gives me this and I can't understand why angone needs more. The coolant temperature varies throughout the system, the temperature at one point is nothing more than an indication of the true condition of the system
