Temp Guage Seem High After Coolant Change, Normal?

[dchan865]

Greetings fellow owners,

I just did a drained and filled on my 2000 RX300 with Toyota long life coolant with 50/50 solution.

After testing driving it for 30 minute on street and freeway with heater on, the temp guage needle consistently stays at about 1/16 inch over the 2 notches. I don't recall what it was normally before my coolant change. I sense that its a bit high.

Back of my mind tells me that it should be below 2 notches.

What's are you folks getting? If you guys are getting lower reading, any idea what could be the problem?

Thanks for any input.

All the Toyota/Lexus vehicles I have owned the temp gauge has been just below half way.

I take it Toyota LLC doesn't come pre-mixed in the US?

If I understand you correctly, I mixed the coolant myself, 50/50.

Toyota does sell premixed coolant in the U.S.

I am also wondering if air trapped in the system could be triggering this. If that's the case, I wonder how I can get it out.

might be a small amount of air but nothing to worry about as air usually drains itself

Both my 2000 and 2001 RXs read about 1/16 over the second notch and have not changed since they were new.

Ok, since you are getting the same thing then I wouldn't worry about it. Sometimes its hard to figure what is normal or not when it comes to reading the temperature, especially the analog type. I hate to have my engine burnt up.

Thanks, Mikey00 for checking it out.
