8. Check Your Battery
The battery helps start the engine and works harder in low temperatures for a number of reasons - so check its condition. One of the early warning signs that it is struggling include a sluggish, churning, sound as the ignition key turns. It's preferable to replace a battery early, rather than wait for it to fail and cause a breakdown. Life expectancy varies, but a reasonable benchmark is 5 to 7 years.
Short trips in winter traffic sometimes don’t produce enough spare power to keep the battery charged. Take your car out for a longer trip on faster roads when you can to keep it in peak condition.
