Car Warms Up Quickly

My 2009 G37S comes up to temp within 2-3 minutes from a cold start. It doesn't overheat, but other cars I've driven usually take double that time. Should I be concerned or is that normal?

Idling or driving? Water temp does not indicate operating temp. Oil temp does. I can guarantee it's not at operating temp when the guage says so.

In addition, you're not really seeing temperature. It's just a feel-good guage run by the ECU.

Driving. Itís a good thing I said something instead of taking it for granted and ruining my engine in the long run. Thanks

it's normal, no concern. the G's water temp gauge does get up to operating range quickly. oil temp is different, but you do get warm air quickly through the heater core if that matters.

i always appreciated the fast 'warm up' in the G compared with my wife's Highlander which takes about double (according to the gauge). i would get warm air a bit before she would.

my G70 is about the same as the G37 was.
