Your car’s engine is one of its most essential and expensive features. Giving the engine regular maintenance should help extend its life and make repairs cheaper. Unfortunately, engines can experience major problems that confuse the average person. When your vehicle’s engine doesn’t seem to work properly, rely on an experienced mechanic to diagnose the issue and recommend repair options.
Here are some of the most common engine problems and the repairs a mechanic might suggest.

Overheating
Overheating can cause minor inconveniences that leave you stranded on the side of the road while you wait for the engine to cool. It can also destroy your engine by causing it to seize. If an engine gets hot enough, parts can literally melt. That usually means you need a total replacement. Hopefully you can avoid that by getting the problem diagnosed before it’s too late.
Some common causes of overheating include:

• Dirty air filters
• Low coolant levels
• Dirty coolant
• Broken cooling fans
• Broken radiator hoses
• Coolant leaks

A mechanic who spots one of these problems should recommend fixing them immediately. Most of them have fairly simple solutions that won’t cost much money. Replacing a hose or dirty air filter is easy for trained mechanic.
Coolant leaks could cost you more money and time, especially if the radiator has a crack in it. If you get maintenance from the same shop over several years, though, your mechanic might spot this problem as it develops.

Poor Air and Fuel Compression
Your engine needs a mixture of fuel and oxygen to create the energy that makes your vehicle move. Poor air and fuel compression can cause sputtering. It can also kill your gas mileage, forcing you to spend more money than usual for your daily commute.
It can also cause your engine to stop working completely.
If your mechanic suspects poor air and fuel compression, he or she will probably check the piston rings to make sure they are in good condition. Broken cylinders, intake valves, and exhaust valves can also cause this problem.

There’s no Spark
Your engine needs a spark that makes combustion happen. If there isn’t a spark, your mechanic will test the spark plugs to make sure they work properly. If that isn’t the problem, then it’s likely a damaged wire or bad ignition timing.
An experienced mechanic will know how to spot these problems and fix them quickly so you can get back on the road
