2004 Toyota Avalon, 135,000 miles. Well serviced. Coolant

Customer Question

2004 Toyota Avalon, 135,000 miles. Well serviced. Coolant flushed/changed a year ago. Currently topped off, not too high, not too low. Driving in the Nevada desert. 110 degrees outside. Temp gauge running higher than I've seen before, about 1/8" below the red box at top of gauge. Should I be worried? Gotta get home to Oregon tomorrow from Las Vegas.

Thanks for posting

The temperature is definitely too high, I drive there a lot of times myself in the summer and even going over mountain passes the temperature stays in the middle or a little above, so my answer is yes this is something to worry about especially if you are going over one of the passes in the Sierras, it could be a simple fix like a thermostat or a cooling fan not turning on or maybe a partially restricted radiator.
