Starting Difficulty in Cold Weather: Common Causes
With persistent cold weather comes an increase in vehicles failing to start. How does cold weather affect your car’s starting?
Reduced battery output
occurs when chemical reactions within the battery are slowed by cold temperatures. Add this to the increased effort required to turn the engine over and you are left with less available current to operate the ignition system
which require additional voltage to operate, compared to new tune parts
Worn tune up (ignition) parts
mean less fuel/air mixture delivery to the cylinder and the result is improperly vaporized fuel mixture. In vintage cars; over-use of choke washes the lubricating oil film from the cylinder walls and causes accelerated engine wear
Lower cranking speeds
(thickness) of lubricating oils leads to higher breakaway and resisting torque. Synthetic oil is less affected by cold weather
If you find it difficult to get your car started, consider having your battery and charging system tested along with checking the condition of tune-up parts.
