(That Aren’t Actually That Big of a Deal)


If you’ve owned a vehicle, you know that car repairs aren’t cheap and can be a real hassle. Sadly, most automotive repairs can be avoided simply by paying attention to preventive maintenance or really inspecting a car before purchase if you’re buying a used vehicle. When will you know if its a good idea to buy a used car, though? How do you know how much a repair is going to cost? In order to help you out, we’ve compiled a list of a mechanic’s biggest repair concerns for used vehicles.


The Beauty of Aftermarket Upgrades


When you purchase an older used vehicle, its typical to find that there have been alterations and repairs done in the past. Possibly upgrades. Something that many people enjoy doing is replacing their stereo or clock for an aftermarket version. This means they took out the old stereo/alarm and replaced it with one that didn’t originally come with the vehicle.


The biggest issue with installing aftermarket equipment is that you’ll end up having to tap into circuitry, which can lead to the power being slowly drained from your vehicle by a short in a circuit somewhere. This repair will end up costing on average about $75.85 and is not something that is generally concerning to a mechanic. However, wiring problems can be more difficult and thus take more time to find and fix. Be prepared for this before you purchase your vehicle.


The Intake Manifold Gasket


The intake manifold gasket failing can be concerning, but isn’t such a big deal if repaired quickly.

The intake manifold is a steel, aluminum or plastic container that fits over the top of the engine. It’s connected to the engine by an intake manifold gasket or gaskets. It’s primary job is to direct the air-intake to the cylinder heads to reduce the temperature in the engine. Overtime, the gasket experiences contracting, heat and expansion and this results in leaking. The repair and just the name of the parts can sound daunting, but the repair for this is actually quite simple.

Your mechanic will replace the gasket, as well as change your coolant and oil, because when you have a leaky intake manifold gasket, coolant will leak into your engine oil. This repair will end up costing an average of about $326.74.




The sparkplugs take their marching orders from our friend, the ignition coils.

The ignition coil is an induction coil into a vehicle’s ignition system that turns a few volts into thousand and lights the spark plugs that burn the fuel and let us drive.  Ignoring an issue or purchasing a car with this issue and not being aware of it can result in extensive damage to a car’s entire ignition system. When purchasing a used car, talk to your mechanic about your concerns and about how much a repair will cost. A repair for the ignition coils will cost an average of about $213.16.


Exhaust Recirculation Valve


Exhaust gas recirculation works by circulating a portion of an engine’s exhaust gas back to the cylinders. This is done to dilute the amount of O2 that exists within the incoming air stream and provides gases inactive to combustion to act like absorbents to the combustion heat, reducing peak-in cylinder temperatures.

This is a semi-easy repair and nothing to get excited or panicked over. However, you will want to check a used car out for this issue prior to purchase due to the amount of times there’s been vehicle failure in the last ten years that were caused by the exhaust recirculation valve.

This repair will run on average about $288.19



Purchasing a used vehicle is scary, but it doesn’t have to be. Take it from the experts, and always give a car a glance over before panicking about anything before you purchase. If you’re not sure about a repair, or wonder whether or not it’s worth it, consult a mechanic and find out how much the potential repairs might cost. Factor it into the total price of the car and make an informed decision.
