5 Common Auto Repairs, Causes & Solutions

5 Common Auto Repairs

As we mentioned in our last blog post, auto maintenance is key to preventing costly auto repairs. This is simply because extensive auto repairs are often pricey, and if you take the time to perform routine maintenance and small repairs along the way, you can avoid the need for big, costly repairs.

In today's blog post, we are going to look at some of the most common repairs, symptoms, and solutions. While many of these repairs can be performed at home by a novice mechanic, not everyone has the time to tackle all of their auto services. If you find yourself in need of help, stop by or contact our Loveland auto shop today! Our team of auto mechanics and technicians have years of experience, and we take pride in our ability to provide expert auto repairs for an unbeatable price.

Catalytic Converter Replacement

The catalytic converter is an essential part of your exhaust system. It neutralizes the hazardous compounds in your exhaust. While they are designed to last for the entire life of your vehicle, other auxiliary problems can cause your catalytic converter to break down. Before you commit to a full (and costly) replacement, it's worth looking to a catalytic cleaner. These only cost a few bucks and are quite easy to use. However, if this doesn't solve the problem, it may be time to bite the bullet and get a replacement.


  • Reduced fuel efficiency
  • Loss of engine power
  • Failure to start
  • Service engine light

Oxygen Sensor Replacement

A faulty oxygen sensor is a very common problem, especially in older vehicles. The function of this sensor is to detect and monitor the uncombusted oxygen in your exhaust. Over time, this sensor can become gummed up with carbon and other deposits. Similar to the catalytic converter, this is a problem that can sometimes be remedied with a catalytic converter cleaner and should, therefore, be the first troubleshooting step you take. However, not all cleaners are formulated to clean the oxygen sensor so be sure to look for one that is designed to do this. If this doesn't work, it will likely need to be replaced.


  • Reduced fuel efficiency
  • Vehicle jerks when accelerating
  • Emits a rotten-egg smell
  • Engine sounds rough when idling


Spark Plug & Ignition Coil Replacement

Spark plugs. They are one of the most classic repairs because they are both important and easy to replace (not to mention affordable). This task is as simple as opening up the hood, removing the coverings, removing the old plugs, and replacing with new, shiny plugs (just make sure you don't overtighten them, which can cause them to misfire).

Along with spark plugs, the ignition coil is another integral part of the vehicle's ignition system. It converts the power from the battery into a high voltage supply capable of powering the spark plugs. The ignition coils can wear over time or become damaged because of bad spark plugs or water damage. While a broken coil cannot be repaired — it must be replaced — this is a rather simple replacement. When replacing your coils, you should also replace your spark plugs. If this problem isn't remedied as soon as possible, it can lead to much more expensive repairs.


  • Difficulty starting vehicle
  • Poor acceleration
  • Rough idling/shaking engine
  • Engine misfires/sputtering sounds
  • Check engine light

Thermostat Replacement

As you may have guessed, the thermostat is responsible for monitoring the temperature of the engine and regulating the temperature via the cooling system. If your engine isn't properly cooled, this can cause your car to run under capacity and may put some damaging (costly) strain on your engine. This is a very common problem with older vehicles and another common trigger for a check engine light.


  • Engine quickly overheats
  • Temperature gauge changes erratically
  • Coolant leaks around the thermostat housing

Fuel Cap Replacement

While you may think this repair seems trivial and unworthy of this list, it is, in fact, a frequent repair and top cause for triggering the check engine light. This can actually be a relatively comforting problem. For example, if your check engine light comes on and you inspect your fuel cap to make sure that it is sealing properly and find that it's not, you've got an easy solution. Simply throw out the old fuel cap and get a new one, and the problem is solved. It's a cheap and easy fix.


  • Reduced fuel efficiency
  • The smell of fuel in the vehicle
  • Check engine light

But wait what about radiators, water pumps, serpentine belts, solenoid, mass air flow sensors, and other problems? You're right! These, too, are common problems, and we look forward to addressing them in a future blog post.
