How fast should it take a 97 sc300 to heat up and where should it stay? Here is a picture of my temp gauge after about 3 miles on none highway..............does this seem high?

 

sounds like the thermostat is doing its job...

if anything, thats a little low... nothing to worry about...

 

Looks good to me.

 

thats normal.. mine is usually lower but if it doesnt go up all the way to H then ur fine :]

maybe just flush the radiator fluid and change the thermostat if ur paranoid haha

 

Thanks guys for the help, its just that this is my first Lexus. I have mostly been an American Muscle guy and over the past few years I have been into the imports so Im not sure whats normal for them yet in certain areas.
