So bundle up and let’s dive into solving the mystery of why your ATV is being so stubborn in chilly weather!
Why Won’t My ATV Start When It’s Cold Outside?
When the mercury drops, your ATV may decide to take a winter siesta. But why does this happen? One possible reason is that cold temperatures can wreak havoc on your battery. Cold weather causes batteries to lose their charge more quickly, making it harder for them to crank over and start the engine. Another culprit could be your fuel system. As temperatures drop, gasoline tends to become thicker and less volatile, making it difficult for the engine to ignite properly.
Don’t forget about those spark plugs! Cold weather can cause spark plugs to foul or malfunction, leading to ignition problems. It’s important to regularly check and clean your spark plugs during colder months.
Engine oil plays a vital role in lubricating all the moving parts of your ATV’s engine, but when it gets too cold, it can thicken up and become sluggish. This can make it harder for the engine components to move smoothly and hinder starting.
Let’s not overlook the air filter. In cold weather conditions with snow and ice present, moisture can accumulate in the air filter housing. This excess moisture can impede airflow into the engine causing starting issues.
Now that we’ve explored some potential reasons behind why your ATV won’t start in the cold, let’s dive deeper into each component mentioned above – battery, fuel system, spark plugs, air filter and engine oil.
Things To Check If Your ATV Won’t Start When It’s Cold Outside
When the temperature drops and you’re ready to hit the trails on your ATV, there’s nothing more frustrating than a machine that won’t start. Before you panic or call for help, there are a few things you can check yourself to get your ATV up and running again.
First, check the battery. Cold temperatures can cause a weak battery to lose its charge quickly. Use a voltmeter to test the voltage of your battery. If it reads below 12 volts, it may not have enough power to start your ATV.
Next, inspect the fuel system. Cold weather can cause condensation in your fuel tank, leading to water getting into the fuel lines and clogging them up. Make sure there is no water or debris in the fuel tank or lines.
Don’t forget about checking the spark plugs as well! These small but vital components ignite the fuel mixture in your engine. Remove each spark plug one at a time and inspect them for signs of wear or fouling.
Another important aspect to look into is engine oil level and quality. Low-quality oil or low levels can make starting difficult in cold conditions as it thickens when cold which makes it harder for parts of an engine like pistons move freely within their cylinders.
Don’t overlook checking the air filter. A dirty air filter restricts airflow into your engine making it harder for combustion to occur efficiently causing starting issues especially in colder temperatures where denser air could be required.
Checking The Battery
One important component to check if your ATV won’t start in the cold is the battery. Cold temperatures can have a significant impact on battery performance, reducing its ability to provide enough power to start the engine. Here are some steps you can take to check your ATV’s battery:
- Visual Inspection: Start by visually inspecting the battery for any signs of damage or corrosion. Look for loose connections and make sure everything is securely attached.
- Voltage Test: Use a multimeter to measure the voltage of your ATV’s battery. A fully charged battery should read around 12.6 volts or higher. If it reads below this level, it may need recharging or replacing.
- Load Test: Conduct a load test on the battery to determine its capacity and health under real-world conditions. This involves applying an electrical load while monitoring voltage levels and observing how well the battery holds up.
- Recharge or Replace: If your battery fails either test, it may need recharging using a charger designed for ATV batteries or replacing with a new one that meets your vehicle’s specifications.
Remember, maintaining proper charge levels in your ATV’s battery is crucial for reliable starting in cold weather conditions!

When it comes to starting your ATV in the cold, a faulty fuel system can often be the culprit. So, if you’re having trouble getting your engine running on those chilly mornings, it’s important to check your fuel system for any issues.
First things first, make sure you have enough fuel in the tank. It may seem obvious, but sometimes we overlook the simplest solutions. Next, inspect the fuel lines for any cracks or leaks. These could be causing air to enter the system and disrupt proper fuel flow.
If everything looks good so far, move on to checking the fuel filter. A clogged or dirty filter can prevent adequate amounts of gasoline from reaching your engine. Consider replacing it if necessary.
Now let’s take a look at the carburetor. Over time, debris and gunk can build up inside this component and cause poor performance. Carefully remove and clean it using carburetor cleaner spray.
Don’t forget about the fuel pump! Ensure that it is functioning properly by listening for its humming sound when you turn on the ignition.
By following these steps and addressing any potential issues with your ATV’s fuel system, you’ll greatly increase your chances of starting successfully even in cold weather conditions.
Checking Spark Plugs
Spark plugs play a crucial role in the ignition process of your ATV’s engine. If your ATV won’t start in the cold, it could be due to faulty spark plugs. Here’s how you can check them:
- Start by locating the spark plug on your ATV’s engine. It is usually connected to thick wires and can be easily spotted.
- Carefully remove the spark plug wire from its connection point on the plug itself.
- Inspect the spark plug for any signs of damage or wear, such as cracks or blackened electrodes. If you notice any issues, it may be time to replace them.
- Use a spark plug socket and a ratchet wrench to remove the old spark plug from its housing.
- Once removed, examine the electrode gap – this should be set according to manufacturer specifications (usually indicated in your owner’s manual). Adjust if necessary using a gap tool.
- Before installing new spark plugs, apply a small amount of anti-seize compound to their threads to prevent corrosion and make future removal easier.
Remember that regular maintenance of your ATV’s spark plugs is essential for optimal performance, especially during colder temperatures when starting can become more challenging.
Checking Engine Oil
When it comes to starting your ATV in the cold, checking the engine oil is an important step. Cold weather can cause the oil to thicken, making it harder for your ATV’s engine to turn over. So how do you check the engine oil?
First, make sure your ATV is on a level surface and turned off. Locate the oil dipstick, which is usually near the engine or under a small cap labeled “oil.” Remove the dipstick and wipe it clean with a cloth or paper towel.
Once cleaned, reinsert the dipstick all the way back into its tube and then remove it again. Take note of where the oil level falls on the dipstick. There should be two marks indicating minimum and maximum levels. If the oil level is below or close to minimum, you will need to add more oil.
If adding more oil doesn’t solve your cold-starting problem, there may be other issues at play such as fuel system problems or spark plug issues. It’s always best to consult a professional if you’re unsure about diagnosing or fixing any problems with your ATV.
