Hi everyone,
I am new to the forum and had a question about the engine running temperature of my 2007 ES 350 with 179k miles.
I have noticed in the last few days that when driving at highway speeds in 65 degree weather the engine temp drops to about a 1/4 on the gauge then when I come to a stop and idle for 2 minutes or so the temp will rise back up to one tick below the 1/2 way mark on the gauge (which is where it usually stays when at operating temp).
I have not gotten any warning lights and the motor still seems to run smooth and strong with no noticable change in idle.
