Engine failure is a dreaded scenario. A broken-down engine can leave your car completely inoperable and cost a ton in repair costs, so it’s natural to wonder whether your insurance policy will cover engine failure. Read on to find out which situations your insurance policy will cover your repair costs and what other options can cover an engine failure.

What Type of Car Insurance Covers Engine Failure?

Familiarizing yourself with the basics of auto insurance in Ontario is an important step to understanding whether your policy covers engine failure.

In general, standard auto insurance policies do not cover engine failure unless it results from a specific incident that is covered by your policy. If your engine fails due to wear and tear, lack of maintenance, or other preventable issues, your auto insurance will likely not cover the costs. Insurers typically view maintenance as the owner’s responsibility, so engine failures resulting from neglect are not covered.

What Causes Engine Failure?

Engine failure can occur for a variety of reasons, and understanding these causes can help you prevent costly repairs. Here are some of the most common culprits:

Overheating

This is often caused by coolant leaks, a malfunctioning thermostat, or a broken water pump. When the engine runs too hot, it can lead to severe damage, including warped cylinder heads.

Oil Starvation

Engines rely on oil for lubrication. If the oil level is low due to leaks or if the oil hasn’t been changed regularly, engine components can seize up, leading to failure.

Neglected Maintenance

Regular maintenance is crucial. Failing to change oil, replace filters, or check fluid levels can lead to a host of problems, including engine failure.

Understanding these causes is vital since many of them can be prevented with proper care and maintenance.

What Other Options Cover Engine Failure?

If you’re concerned about engine failure and want additional protection beyond standard auto insurance, consider extended warranties.

If you’ve just bought your car, you have the option to purchase an extended warranty from the dealership or manufacturer. These warranties can provide coverage for engine repairs after the original warranty expires, but they often come with specific terms and conditions.

Maintenance Tips to Prevent Engine Failure

Maintenance Tips to Prevent Engine Failure

Preventing engine failure is often easier and cheaper than dealing with repairs. Here are some maintenance tips to keep your engine running smoothly:

Regular Oil Changes

Your engine oil keeps the moving parts lubricated and operating smoothly. Change your oil as recommended by your manufacturer. This helps maintain proper lubrication and prevents sludge buildup.

Monitor Fluid Levels

Regularly check your coolant, oil, and transmission fluid. Low levels can lead to overheating and other issues with your engine.

Inspect Belts, Hoses, and Spark Plugs

Check your engine’s parts for signs of wear, such as cracks or fraying. Replace them as needed to prevent breakdowns.

Pay Attention to Warning Lights

If your check engine light comes on, don’t ignore it. Have your vehicle inspected by a qualified mechanic to catch potential problems early.

By following these tips, you can help extend the life of your engine and reduce the likelihood of costly failures.

Bottom Line

  • Regularly check your engine and perform maintenance to minimize the risk of an engine failure.
  • Consider purchasing an extended warranty for your vehicle if you’re worried about engine failures.
  • Your regular insurance policy coverage will only cover engine failure if it’s a result of a collision or event you’re insured against.
