When towing, you might encounter a temporary cooling system overload during severe conditions, such as: • Hot days when pulling on a long grade • When slowing down after higher speed driving • Driving with long, idle periods in traffic jams If the tow vehicle’s temperature gauge or indicator light indicates overheating, and the air conditioner is on, turn it off, pull over in a safe place, and apply the emergency brake. Increase the engine idle speed. Lift the engine hood and check for fluid leaks at the radiator overflow outlet. Ensure all drive belts are intact and the radiator fan is turning.
If you have a problem, have it fixed at the next opportunity. If there is no problem, the light should go off or temperature should come down within 1 minute. Proceed on the highway a little slower, and resume normal driving after 10 minutes.
Tip: Never open a radiator cap when the tow vehicle is hot. Check the coolant level when the vehicle is cool.
