Step 1
Check your tires. A properly inflated tire puts less stress on the engine. Don't forget to check the spare.
-
Step 2
Flush the old anti-freeze/coolant from your car's cooling system and replace it with fresh. Be sure to take the time to do this step, especially if the anti-freeze/coolant is over a year old.
-
Step 3
Inspect the serpentine belt that operates the motor and replace it if you see noticeable cracks. You may need to take your car to a mechanic to have the belt changed, as it requires special tools.
-
Step 4
Get the car's HVAC system tested. The middle of the desert is not a good place to find out the air conditioning system has leaks in it or that it doesn't work.
-
Step 5
Consider filling your gas tank with a higher-octane fuel than you normally use. It can help your car's motor run more efficiently, thus helping to prevent the motor from overheating in the desert. Make sure you have enough gas to get between towns in isolated areas.
-
Step 6
Switch off the air conditioner on long, steep inclines to help prevent overheating the car's engine. At the very least, turn the fan to low.
-
Step 7
Remember to pack an emergency survival kit in case your car does break down. Place anti-freeze/coolant, extra motor oil, foam tire sealant and water for the battery in the trunk. Also carry basic tools such as wrenches, screwdrivers and pliers. In case a hose breaks, pack some duct tape to make a temporary patch.
