Starting your vehicle in extreme temperatures is a common topic at our St. Peters, MO automotive repair facility. Mechanics and Technicians across the St. Louis area agree on a few Key points.
Make the most of your Power
When the temperature drops, your battery begins too lose it's starting power. Use the energy wisely by turning off all accessories including the heater, radio, defroster, and lights before you attempt to start your car.
By the Book
The most accurate direction for cold weather startup will be found in your operator's manual. Generally you should turn off all your accessories. Carbureted vehicles should have the pedal pushed to the floor once, then released before starting. Fuel injected vehicles, don't touch the pedal. Turn the key and hold it for only about 20 seconds. If the vehicle fails to start, wait a few minutes and try again.
Check and Use the Proper Fluids
The antifreeze should test to -35 deg. below zero. Should the level be low, add a 50/50 mixture of antifreeze and water. Don't foget your washer fluid! Make sure to run 100% solution of washer fluid in the cold to prevent freezing.
Prevent Freezing
You can prevent your gas line from freezing by keeping the tank full and reducing condensation. You should also try to avoice using alcohol blended fuels as the alcohol attracts and retains moiture.
The Right Oil
Extreme temperatures make engine oil thicker, which slows down it's flow rate and prevents it from reaching vital components that need to be lubricated. Make sure to check your operator's manual for the correct viscosty to fun in the winter.
Start out Slow
Let your engine run for at least a minute before you start driving, but don't accelerate too quickly during the first mile or two.
