Cat Engine Operating Temperature

4 posts in this topic

I have a 2005 CC Inspire #51264 with a Cat C-9 Engine Serial # 9DG01439. My normal operating temperature when fully warmed up runs between 200-205 degrees F. I usually run at 65 mph, my temperature remains fairly constant regardless of ambient temperature or when pulling grades. My question is, is this operating temperature normal/ok.

Thank you,

RJ

Best advice is to call the Caterpillar RV Hotline with your engine serial number. They can look up your actual engine and give you the FACTS.

Caterpillar 877 777-3126.

You can verify the reading with a infrared temp gauge at the sender. Since it doesn't vary under different conditions its probably ok, but the gauge may be reading a little high.
