About Car Warning Lights

5 Secrets Your Car Mechanic Doesn’t Want You to Know - About Car Warning Lights
engine check light

You get warning lights on in your dash, let’s say your check engine light comes on,

your ABS light is on and your track light all come on there all three shine and while you’re driving.

Well in many modern cars it has to do more with the software and the design of the car than actual problems.

On many cars especially Toyota’s Lexus, if you have a problem and your check engine light comes on automatically that will turn off the ABS and traction control systems.

abs and traction light

It’s a computer safety thing. 

So you’ll have these three lights you think, or all these things are happening in my car but, in reality the only real problem is the check engine light.

So in that case have it scanned and see what the check engine code is and have that fixed first.

I’ve had more people before they met me spend a whole bunch of money having working quotation mark done. 

And other mechanics only later they come to me with the same thing that all those lights are on and it turns out that they got charged for ABS work, traction control work.

That probably wasn’t even done on the car.

Because there was another problem that the mechanic didn’t fix right so they all came back on again.


So if your check engine light comes on, and the ABS and the traction control lights are all on at the same time, don’t have a fit.

First find out why the check engine light is on and fix that, that often fixes the whole thing.

Maintenance Required Light

5 Secrets Your Car Mechanic Doesn’t Want You to Know - Maintenance Required Light

The next has to do with the maintenance required light.

As far as I’m concerned the maintenance required light that is one of the biggest scams out there.

Manufactures put them in to scare people to bring the car to the dealer.

Those stupid lights on most cars will just come on at certain mileage intervals some cars will come on every 15,000 miles. 

What you want to do is of course maintain your car correctly change the oil when you need to. 

But learn how to turn that maintenance required light off yourself.

Because often the only thing the car needs when the maintenance required light comes on is an oil change.

Do what yourself or have it done somewhere. 

Just Google for your own car turning off maintenance required light and you’ll see there are certain buttons you have to push in a certain sequence and you can turn it off yourself. 

Don’t freak out and go running to the dealer and get some gigantic bill for things that you really don’t need to have done at all.

Don’t Spend Money On Additives

5 Secrets Your Car Mechanic Doesn’t Want You to Know - Don’t Spend Money On Additives

And the next mechanics tip is this, on any normal car don’t waste your money on expensive additives to stick in the engine or the transmission or the gas tank.

Now of course companies make the stuff so they want to sell it to you.

And let’s say you bought a used car and it’s a real junker and it’s got something leaking or it burns a lot of oil.

You can try some additives to attempt to help it a little bit. 

But in a normal functioning car that you take care of it’s a waste of money to buy that stuff. 

Modern gasoline it’s got plenty of additives especially in the United States by law,

the stuffs going to burn perfectly fine.

You don’t need to put anything else in it.

It works great the way it comes from the refinery. 

And the same thing goes for engine oil, engine oil works really good its well-designed.

All the chemicals that are added to the oil to make it last longer,

to make it not burn, to make it not pollute and vaporize.

They’re in there from the factory, you don’t need to add a bunch of packages yourself you just need to change the stuff regularly. 

That’s what you need to do not put additives in, change your oil when it gets dirty.

About The Car Heater

About The Car Heater

If your car’s heater doesn’t work right, maybe it’s lukewarm maybe doesn’t work at all, a lot of times

it’s because of one simple thing. 

And that simple thing is this, if your car is low on coolant often your heater won’t work right. 

Now this may sound counterintuitive but it’s true.

About The Car Heater core

Your car’s heater core that the hot water goes through and then the air blows and puts hot air on you,

is inside the dash most of the time it’s usually the highest part of the cooling system.

And as crazy as it sounds, the heater core only works with hot water inside, it doesn’t work with hot air.

So if your cooling system is low on coolant, since the heater core is the highest part,

it gets filled up with air and the liquid goes back down into the engine.

And hot air won’t blow into your car, it has to be full of hot water that dissipates the heat through the fins and your fan blows the hot air in your face.

So if your here is not working this winter, hey just check your coolant level it might just be low. 

About Your Car Battery

About The Car battery

Now the last mechanic secret has to do with car batteries.

Modern batteries are filled with acid at the factory, it’s just a new production thing.

But once batteries filled with acid, they start to deteriorate.

And batteries made to start the car,

discharge a little then the alternator recharges it, then start and stop.

If you fill them with acid and put them on a shelf and they sit there for months on end,

they start to degrade then they lose a lot of their lifespan.

When you’re buying a battery for your car, pretend you’re at the grocery store,

demand to see the date of the battery and try to get one that’s less than a month old. 

Because they don’t deteriorate that much in one month.

But don’t go to one of those big box stores where they got batteries all piled up in a giant pyramid and buy one there.

Who knows how long that thing’s been sitting at the bottom of the pyramid,

always get a fresh battery when you buy one.

Final Words
