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

 

 

Increased viscosity

 

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.
