No auto professional who cares about you will advise you to make changes to your car’s system. Some of these roadside mechanics will always provide you with ominous and unethical advice in an effort to drain your bank account, wreck your automobile, and trap you so you keep returning to them. 

You could unintentionally buy into these people’s notions out of ignorance or a desire to avoid incurring a significant financial outlay when doing the correct thing. You can come to regret taking such actions in the long run. You won’t have made a purchase by then, and it will be too late to turn around. Then you’ll only have a headache and a run for your money.

I’m confident that you wouldn’t want them all. Therefore, you must have the fortitude to resist their advances and act morally whenever possible.

The truth about some of these shoddy modifications to automotive systems is that they will hurt you more than they will help. In addition to causing you to spend more money than you intended to, it will also take away your tranquillity.

Let’s get started to see some of these automobile system modifications that, for your own peace of mind, you should avoid.

Gearbox/Transmission Conversion

Avoid any mechanic who tempts you to convert your gearbox under the pretence of trying to save you money. If the gearbox is destroyed, it is better to close your eyes, gather your money, and buy a gearbox specifically designed for your vehicle to replace it. Don’t fall for their carefully crafted lies about using a different gearbox for a different car just because it is less expensive.

A 2009 Toyota Camry SE (4-cylinder) with a U250E transmission is a fantastic illustration (popularly known as a 13-pin gearbox in Nigeria). Some malicious mechanics would advise using the 10-pin gearbox, which is considerably less expensive, rather than replacing the damaged gearbox with a decent one.  They’ll tell you that after installation, they’ll take the automobile to be rewired to make certain connections to ensure that everything functions perfectly.

Therefore, flee and ignore them. Starting such a technological journey has a significant failure rate. Most of the time, it does not work out well, and you will undoubtedly find yourself back where you started.

Taking the engine thermostat out

Another change that most Nigerians fall for is this one. But first, what exactly is this thermostat, and what does it do? For every liquid-cooled automobile engine, the thermostat is positioned between the engine and the radiator. Its task is to obstruct the radiator’s coolant flow until the engine has warmed up. No coolant runs through the engine when it is cold. To put it another way, it guarantees that the engine is operating at its ideal temperature.

Your engine won’t operate as it was intended to if you completely remove it from the system. This accelerates internal engine wear and tear, hence shortening the engine’s useful life.

Turning Off the ABS System

When their ABS malfunctions, some people will even disable it. Most mechanics simply remove one wheel’s speed sensor to turn off the ABS. Unplugging your car’s yaw rate sensor will produce the same results. This could be a serious issue in some vehicles since it can result in a lack of stability while braking hard because the back brakes lock up too early.

Inadequate upgrading

Are you one of the individuals who find irrational satisfaction in replacing a 2002 Toyota Landcruiser with a 2020 model? Please stop; it’s time to move on. There are some enhancements that will actually cause the car more harm than good. Any upgrades that compromise your car’s structural integrity should be avoided.

Direct connection to a radiator fan

When you turn on your car, this type of connection causes your radiator cooling fan to begin operating continuously. The majority of these automobiles aren’t made to operate that way. They employ a thermostat to control when the radiator cooling fan activates and at what temperature. It is set up to ensure that your engine operates at the ideal temperature, just like the engine thermostat.

The cooling system is changed, which has consequences when a roadside Kazim runs a direct connection for you.

Frequently Asked Questions 

How Often Does My Car Need Maintenance?

That depends on your vehicle. Some types of service should be done more regularly, including brakes, fluid checks, and oil changes, while timing belt replacements are among the services you might only need once or twice. Time and mileage intervals are key factors, which your vehicle’s manufacturer should list. Your car, truck, or SUV also has internal clocks, so indicator lights will notify you when maintenance is required.

Why Should I Replace My Light Bulbs?

Adequate lighting is essential for other drivers to see you, so it’s a safety requirement. There are over 100 light bulbs in the average vehicle, and one in three vehicles has at least one burned out. Spotting burn-outs is part of a routine inspection, which is one more reason to have your vehicle inspected. You can receive a traffic violation for driving with a burned-out headlight or tail light.
