Car won't start on a cold morning

Cold weather cuts the power a battery can deliver while the engine oil gets thicker and harder to turn, so a weak battery often gives out on the first cold morning. A jump start usually gets you going; if it happens again on the next cold day, replace the battery.

Likely causes

  • Battery already weakened by last summer's heat
  • Cold cutting the battery's available power
  • Thick engine oil making the engine harder to crank
  • Heater, defroster or lights left on from the night before
  • Corroded terminals

Try this first

  • Turn off the heater, defroster, lights and radio before starting
  • Crank for just a few seconds at a time, then rest about a minute
  • Press the clutch in if you drive a manual
  • Wait indoors instead of sitting in a cold car for a long time

When to call us

  • It cranks slower with each try
  • It just clicks
  • You need to be somewhere this morning and can't wait for the day to warm up

Questions

01Will the car start once it warms up outside?

Sometimes a borderline battery will start later in the day, but don't count on it. A battery that fails in the cold is telling you it's weak.

02Can I warm up the car in the garage after a jump?

Never run the engine in a closed garage. Exhaust fumes build up and can be deadly. Open the garage door fully or move the car outside before letting it idle.
