How To Diagnose Your Car DIY Style


For most of us, when our engines begin rattling, we immediately rush into an auto shop for car repair quotes. Although it’s recommended to ensure your vehicle is adequately maintained, being quick to hire a mechanic may need you to break the bank. You’ll end up paying for repairs that you would have handled, and some repair stores can find other costly components to replace regardless of whether your vehicles need them or not. Having a better comprehension of some vehicle issues can save you money. When you determine that an issue requires an expert Car mechanic in Coorparoo, you’ll know how much it will cost to fix it. The following are ways of diagnosing your car issues by yourself.

Exhaust Smoke

Keeping a keen eye on what’s emitted from your exhaust is a prudent way of identifying car problems before they get worse. White smoke emanating from the tailpipe indicates a leaking coolant, which can lead to engine overheating. Blue smoke indicates oil is leaking from paths leading to the engine and leaking in fuel. A gas and oil combustion gives blue smoke.

Determine whether your vehicle has been using excessive oil amounts and ensure your engine is examined immediately to identify the source of oil leaks. Black smoke from the exhaust implies you are combusting excessive amounts of fuel. To prevent wasting more gas, analyze the air filter and other components such as fuel injectors and sensors to ascertain if they’re malfunctioning.

Use the internet

If you are facing difficulty when diagnosing your vehicle problem, make Google your friend. Sites such as will help identify what’s ailing the car. You can also visit YouTube or “How-to” sites for Do-It-Yourself tips. Be sure to call a certified mechanic for severe cases that require a trained eye. But ask a mechanic in Coorparoo about costs before they conduct any fixes and discuss prospective fixes to ascertain whether they’re necessary.

Read the DTC (Diagnostic Trouble Codes)

Begin your vehicle diagnostic test by reading the Onboard Diagnostic Codes (OBD codes, also referred to as DTC). The DTC is mandatory in the U.S since 1996 and consists of a list of trouble codes for self-diagnostic results. Thus, for all automobiles bought after 1996, you can use an OBD2 standard scanner to perform a vehicle diagnostic test. The OBD2 Scanner enables you to read your vehicle trouble codes or check your engine’s light codes from the car computer.

Although it doesn’t say what the issue is specifically, it tells you what the problem could be and how to diagnose and fix it.

Brake Pads

Brakes are the most critical aspect of the vehicle since they ensure safety when you’re driving. It’s essential to keep your brakes in optimum condition to avoid brake failures that may lead to car carnage. To change your brake pads, loosen wheels’ lug nuts, jack your car up, remove the wheels, remove slider bolts and put wheels back securely. Be careful when using replica wheels; it’s another DIY that saves you money.

Taillight or headlight

Driving with a broken taillight or headlight is inconvenient and illegal. Thus, you need to swap them when they start fading using a DIY replacement. Remove the screws attaching your headlight frame on the bracket, detach your electrical connector, remove the faulty light and install a new one, plug the connector back and replace the frame. For a broken frame, use this process to change it.

Use TPM (Tire Pressure Monitoring)

This is one of the fundamental self-diagnosing units and informs you when your tires are flabby. More advanced luxury cars will indicate the specific low tire and by what amount.

Their TPM systems can draw a diagram on the console screen and blinks, beeps, or turns red when things are abnormal.

Replacing the car battery

Car batteries often die during the most inconvenient moments. If you are stuck in an unknown location, it would be best to ask for roadside help or contact tow truck firms. However, if you’re home and the battery requires a replacement, start by removing the battery covers then disconnect negative cables. After moving the clamp from your battery post, remove screws, swap the old battery using a new one, and reconnect your cable clamps. Ensure your cables are labeled before removing them.
