Engine Maintenance & Repair – What You Need To Know


It’s not uncommon to have questions about your car’s maintenance and repair. It can be confusing for first-timers, but there are plenty of resources available to help you out if you’re unsure about what needs to be done or when. If you’ve been driving for a while, there may still be some things that aren’t clear on how often you should change the oil in your car. Or maybe you’re looking for tips on how to safely change an air filter? These questions and more will all be answered here so that your vehicle is up and running like new again!

What is the service interval?

The service interval is the time between oil changes. It’s determined by the manufacturer and based on the type of oil and filter used, as well as your vehicle’s mileage. You should always follow your vehicle manufacturer’s recommendations for servicing your engine, but it’s also important to keep in mind that you can’t just change your engine oil whenever you want–you have to stick with a schedule!

What are the key components of your engine?

  • The engine block is the main component of any engine. It houses all of the other parts, including:
  • Cylinder heads (also called a head)
  • Injectors, which deliver fuel to combustion chambers in your cylinders. These can be electronic or mechanical, depending on your vehicle type and year model.
  • A starter motor that starts your car when you turn on its ignition key or push down on a button inside the vehicle’s cabin area.
  • Alternators generate electricity for automotive power systems by converting rotational energy into electrical energy through electromagnetic induction–and they’re integral to keeping your car running smoothly!

When should I change my engine oil?

It’s important to know when you should change your oil. The interval between changes will vary by car, so check your owner’s manual or call the manufacturer directly if you don’t know. You can also use this chart as a general guideline:

  • Change every 3,000 miles or every six months (whichever comes first) if you drive under normal conditions and don’t tow anything heavy.
  • Change every 5,000 miles or every three months if you tow a lot of things with your vehicle (for example, an RV).

How often should I check my engine coolant level?

Your engine coolant level should be checked every time you fuel up, as well as before long trips (especially in hot weather) and after car washes or accidents. This can help prevent damage from overheating and freezing, which can cause extensive damage to your vehicle’s engine if left untreated.

Should I use a cooling system flush or a coolant refill every time I change my oil?

You may have heard that it’s important to flush your cooling system every time you change your engine oil. This is not true! Flushing the coolant can damage your engine and void your warranty, so it’s not recommended by any auto manufacturer or professional mechanic.

It’s also expensive: The average cost of a plain old oil change at Jiffy Lube is $24; an “engine flush” costs $65-$75 (and even more at some places). That’s a lot of money for something that won’t fix any problems in your car–and could actually cause them!

Can I drive with an empty fuel tank? How do I know when it’s time to refill the tank?

You should never drive with an empty tank. It’s unsafe, and you risk damaging your engine.

But what does “empty” mean? The average person doesn’t have a good sense of how much fuel is in their car at any given time–and if you’re like me, this question might seem like one of those things that falls under the “I don’t want to think about it” category: it’s just not something we need to worry about until after we’ve run out of gas (or so I thought).

Turns out there are actually two ways we can determine how much fuel remains in our tanks: by looking at our dashboard or by listening for clues from our engines.

Do I need special tools to change my own oil and filter, or are there other requirements that I need to be aware of before getting started?

If you want to change your own oil, then there are some things you will need. A filter wrench is one of them. You can buy one at any auto parts store for less than $20 or so. A drain pan is another thing that everyone should have in their toolbox anyway, so it’s a good idea to get one before starting this project (or any other time).

Then there’s the old filter itself and its replacement–a new one should come with both of these things included in the box along with instructions on how best to use them together with your vehicle type/make/model (if applicable). Also make sure that whatever oil filter wrench set-up comes with this new set-up is compatible with what kind of car engine compartment door opening mechanisms exist on yours!

How often should I change the air filter on my car?

You should change the air filter on your car once a year. If you don’t, it can cause problems with the engine and make it run poorly.

You can find instructions for how to change an air filter in the owner’s manual of your vehicle or on YouTube. It’s not too difficult–you just need some tools and about 15 minutes of time (not including drying time).

It costs around $35-$50 for an OEM-quality replacement filter, but some places sell them for less than $10 if they’re generic brands or off-brand replacements with similar specs as OEM filters so you might want to check those out first before paying full price!
