If your car won’t start in the cold, the best solution combines proper maintenance and options to make a cold start easier on your vehicle. In northern Wisconsin, cold winter weather is a fact of life. My 2007 Saturn Ion starts in weather as cold as -25F actual temp without fail, without any special treatment. (But not everyone is so lucky.) We have a fleet of trucks at work (both diesel and gas) that run in all kinds of weather. I’m drawing on my experience working with them, and from full time mechanics that help troubleshoot when we need them.
If Your Car Won’t Start in Cold Weather, First Check for Proper Maintenance
- Make sure you have the right oil. Most cars now recommend http://www.museum-freiberg.de/ for year round use, or synthetic such as Mobile One.
- Have your battery checked. In our area most auto parts stores will do this testing for free. Car batteries can fail after 3 or 4 years, a quick test will tell you if it needs to be replaced. You can also test your alternator to see if it is charging the battery properly.
- Get service if it is needed. If you have a check engine light on but don’t notice any change in performance, there may still be a problem with your ignition system that will get worse in cold weather. Electronic ignition on modern vehicles is more dependable than ever, but coil packs do fail. There may also be other problems that only a mechanic with the right diagnostic equipment can troubleshoot.
Side note – when you take your car to a service station for oil change, don’t let them fill your washer fluid reservoir. They typically use a low grade washer fluid that will freeze when the cold comes. Once that happens you will be at nature’s mercy until it warms enough to pump it out. reflective essay and social media planning
When Winter Hits – Steps to Improve Cold Weather Starts
Once the cold is here, there several things you can have already installed to warm the key parts to make cold starts easier. Note: Cars and trucks built after 1990 have fuel injection. The recommended starting sequence should be in your owner’s manual.
Use a Battery Blanket
A kayıtsız canlı sohbet siteleri acts like an electric blanket for your battery. Cold weather slows the chemical reaction inside your battery that makes the electricity to turn the starter, and can rob you of 30% of your cold cranking power. It needs to be operation for about an hour to do its job and warm the battery to the core. get a term paper
Try an Engine Block Heater
Engine block heaters come in 3 different types:
- Magnets that attach to the oil or transmission pan
- Block heaters that are installed in the cooling system
- Frost plug heaters
You can install these yourself if you do some research and make sure you have the right style for your particular application. (I would get a mechanic for the frost plug style) When doing research to write this post, I found that Amazon had a built in guide to help you find the right one for your engine. Just type in the make, model and year to find the right fit.
No matter what style of engine block heater you have, an hour should be enough to warm the engine once it is plugged in. There are timers you can purchase that can be set for an hour before you need to start your car that will save you money. Because they create heat, all of these heaters draw quite a bit of current and should be plugged into a 20amp breaker that does not have other appliances.
Start Your Car the Right Way
The way you start your car can improve your chances of a cold start.
- First, turn off the headlights and blower for the heater.
- Next, turn the key to the on position and wait until the dash lights quit flashing. This allows the fuel pump to pump additional fuel in for the cold start.
- Finally, turn the key and crank the engine for up to 10 seconds. If it fails to start, wait 30 seconds and try again. Don’t try this more than 3 or 4 times. At that point the battery will likely be drained and you will need to find a way to recharge it.
To jump start a vehicle – pay attention to the color codes on the jumper cables. Make sure the red goes to the positive post and the black negative ground is attached to the engine block. Allow several minutes for the battery (with the jumper car running) to recharge before you try to start your vehicle. It takes 12 minutes or more for a working alternator to recharge a cold battery, so don’t shut off the car after it is jumped until it has been driven an adequate amount of time.
Cold Weather Start with Diesel Engines
Diesel engines have glow plugs with an indicator light that tells you when they have warmed enough to attempt a start. Diesel engines start harder because of higher compression and a lower flash point for the fuel. For temps below zero, we always plug our trucks in to warm the engine block.
HEET™ Fuel Additive – Yes or No?
Modern fuel contains an ethanol mix of 10% or more, so you shouldn’t need to treat your fuel with “HEET™” gas line anti freeze. (Assuming you use your car regularly.) If you have a diesel engine, you should use a fuel conditioner at the recommended rate. It is also beneficial to keep your tank past half full to minimize condensation in your fuel tank. Water lowers the octane of the fuel and causes poor performance. Additives such as Sea Foam motor treatment can boost octane and remove water for better overall performance.
My Car Still Won’t Start – Now What?
This is an introduction to cold weather car starts, not a complete guide. Always refer to your vehicle’s owner’s manual and back that up with the advice of a reputable mechanic. Modern auto mobiles often stay on the road for 200,000 miles and are complex in design. Sometimes even the professions have problems troubleshooting issues.
