A note - being that you are in San Diego there are a couple things you may not have thought of. Make sure you have a proper coolant (antifreeze) mix in your radiator. Have it serviced before you leave with a 50/50 mix of coolant and water. Also - drain your windshield washer reservoir and buy some winter type fluid once you are out of California. The fluid you get in San Diego and anywhere else in SoCal is only good down to 32F due to your CARB regulations.
