subject: Four Ways To Prepare Your Engine For Cold Weather [print this page] When driving a vehicle in colder climates there are several factors that must considered to ensure the greatest cold start drivability, or the ability for your vehicle to function properly in frigid temperatures. It is important to prepare a vehicle for cold weather; otherwise the ability of a vehicle to start and run may be greatly impacted. If your vehicle does not receive appropriate preparation and diligent cold weather maintenance the effects could be beyond costly, they could be dangerous.
There are several interior problems a cold climate can cause an engine; the likelihood of these problems depends on the type of vehicle, the mileage and age of the vehicle, and specific engine components. Keep these tips in mind when servicing your vehicle for cold weather drivability.
1.Be aware of the quality of your vehicles components. Some vehicles have plastic intake manifolds that can be destroyed by cold weather, for instance. Similarly, fuel injectors may stick closed when temperatures drop.
2.Clean your airflow sensor. Cold weather can affect the airflow sensor of an engine, causing incorrect calculations of the air-fuel mixture to be sent to the engine. Keep in mind that a dirty airflow sensor will always have a negative effect on your engine, but these effects will be exaggerated in cold weather.
3.Check for intake leaks. Intake leaks are more likely in cold weather. If your vehicle is emitting steam while idling, or if there are puddles of water beneath your car you probably have an intake leak. Luckily a smoke intake test can easily determine if you have an intake leak.
4.Be aware of condensation. Cold weather can lead to excessive moisture from condensation to build in your engine. This is particularly evident in the crankcase. The crankcase, which houses the crank shaft, can accumulate moisture because the cold weather doesnt allow the condensation to burn off in its usual manner. This will keep your engine from maintaining the proper heat.
If you live in a region that has cold temperatures or if you are taking a road trip to an area that has a colder climate, be sure to have your car prepared. Driving in winter weather creates many dangerous conditions, including icy roads, poor visibility, high winds, and low temperatures. Be sure to prepare your vehicle properly for these circumstances, so that when driving becomes difficult you can worry about condition of the weather and not the condition of your engine performance.
