210 degrees seems high since 300 is as high as it goes..
what is the normal operating temperature on my 2012 grand caravan? on 2012 Dodge Grand Caravan
Most cars cooling systems are running in that range at 200- 210 nowdays. The engines are designed to run higher temps for fuel emmisions and fuel mileage concerns. Check with your Dodge dealer to be sure.
Remember your running coolant through a pressurized system. water boils @ 212F.(yes , I know you know that , just using it as a reference) Coolant does not. Pressurizing the system also raises the boiling point.Unless you're running your A/C , your rad. cooling fans won't normally come on 'til 215F , but when they come on , if all is functioning properly , coolant goes in the rad. at 215 and a few seconds later it's coming out at 175-180F. Is the 210F you mentioned using an infra-red thermometer or the guage on the dash? The dash guage can vary somewhat in its accuracy.
