The absence of a check engine light does not mean an engine was well maintained.

There are lots of dead engines without check engine light.

Toks cars have been imported into this country with dead engines which "ran" on videos posted by auction companies.

There is no guarantee.

I've seen comatose engines in this country without check engine light and very sound engines in vehicles which had numerous lights on their dash.

so basically people go to scrap yards in the US and buy dead Engines right?You do realize the Engine is the most mechanical part of your car.The Engine on its own if faulty does not bring up check Engine light. Can i ask you something, Do you know what it means to pronounce an Engine dead?

Let me guess?
Presence of a check engine light?

erico2k2:
If you buy a direct used car from Europe or America, it is serviced yearly, so your car will be in good condition, Unless you are one of those who believe in tropicalization.

This assumption is bold. Very bold.

Without a maintenance record, you cannot guarantee that cars were serviced "every year".

And every year might not be the ideal service interval for every car. Several factors determine how often a car should be serviced.

According to you, check engine light right?

You are mostly right on topics but I suggest you let this one slide.
Let's not derail the discussion.

Well, you need a certificate every year to prove your car is road worthy to drive in the west if your car is private no exception and if commercial is 6 months, No exceptions. How is this an assumption? If Nigerians as mechanics have tools as simple is torque. wrenches, Unseized Engines should be easy like ABC.If there is nothing broken inside an Engine. Then you got nothing to worry about.

You are over flogging this check Engine light. All I said was a simple and short statement of fact. If your car is above 2015 i n the Uk and the rest of the west, it will fail MOT if it shows a check Engine light. So something so simple as your car out of Timing will fail your MOT.

Nop, What it means in an Engineering term is literarily, it is dead, it wont turn over ie a seized Engine is DEAD.
Things like Crack block
Broken shafts
Broken or cracked Con Rods. etc then ur Engine is dead

And we don't need such certificates in nigeria?

So an engine with worn out camshafts, lobes, cylinder walls or sleeves, worn piston rings or pistons, worn main bearings, journals etc is still a sound engine?

Or how is the buyer who sourced it from the scrap yard our auctioned vehicle from the west supposed to know? As if a worn journal or main bearing will throw a check engine light?

Oga, leave this matter.

Dead was a literal term. We didn't say it's an engine that can't turn over.
Let me rephrase it. Bad engine.

And e full everywhere even in the mighty "west".

Oya rest.

And failing an MOT test in the "west" for having your check engine light on is not only for 2015 and above cars.

Some states in the USA require cars made way beyond that 2015 even as far back as 2001 to pass the emissions test as well as not having their check engine light on.

This ya west, you dey make am sound like say na only you dey dia.

We don hia. Oyibo engine no dey fail and them no get less than optimal engines.

Their engines no get sludge and them no dey smoke.

Engines sourced from there come with 10 years warranty.

Happy?

The proof of road worthiness is on paper only to be enforced to extort motorist. No one does the actual test, if not 60% of the commercial vehicles on the road wont be on the road.
With all this So an engine with worn out camshafts, lobes, cylinder walls or sleeves, worn piston rings or pistons, worn main bearings, journals, how can your car pass MOT? with all these you just listed ?

So you're saying it's absolutely impossible to rebuild an engine without torque wrench?

ANSWER IS OVERWHEMLY YES
Any one who rebuilds an Engine, Any sort of Engine without a Torque Wrench is a Quack, I challenge any Mechanic on Nairaland to prove me wrong.

Inukwa?


Oga, so it can be done but it makes the person a quack?

There are literally hundreds of thousands of engines running around this country that have been rebuilt without torque wrenches. And they are running just fine.

Are torque wrenches a nice tool to have when rebuilding engines? Yes.
Can an engine be rebuilt without them? Yes.

Stop capping and rest.

I guess my generator mechanic will need to come and rework my gen with a torque wrench cos he didn't use it when he rebuilt it three years ago.

And if you couldn't find logic in my other post, then you may have to read it again but this time slowly.

Check engine ko, yearly service ni.

From all these you haven't got a clue about Engines. I stated there Boldy That any mechanic that opens and close an Engine without a torque wrench is a Quack, Do you see any of them saying anything??
I don't think you have ever held or seen a Torque wrench.it goes beyond belief that you are engaging in these conversation you know next to nothing about. A torque wrench cost less than N30k in todays money. All cars have torque specifications. Lazy mechanic fail and wont learn how to set a torque wrench. This is the case for smoking Engines and braking studs.
If you insist someone should rebuild an Engine without a torque wrench that I insist you stop commenting on Cars.
You talking about running just fine on more than 100s of cars rebuilt, I laugh. Why do you think people complain that their cars consume so much fuel and are looking for fuel efficient cars when in turn they don't even know what that means. People who belong to same school of thought like you are the ones who will buy a new car battery into their 2015 car and wont bother to reprogram the car to re configure that charging ability. Look I have met a lot of mechanic who actually know what they are doing. The have the required tool like that young man who came to free my range rover in 2018 when I got stuck in shagamu on here .Check rad autos on here, there are few good Auto techs on Nairaland.
For enlightment purpose, your car Engine is meant to be tightened to its torque specification and in a sequence. If you do that ,your Engine compression will go back to factory spec.

The irony here is you are talking to someone who uses torque wrenches.

Do you reprogramme a 2015 toyota Highlander to accept a new battery?

Do you reprogramme a 2015 toyota yaris to accept a new battery?

We do not live in a ideal world. Our mechanics do not have a lot of tools to rebuild engines as it should be done but they do just fine with what they have. Those that need the services of mechanics who possess such tools and can afford them, use them.

The fallacy of generalisation is a major flaw you have in your submissions.

That, and your penchant for throwing around outlandish claims.

I suggest you tone down on those.

There are people here who know a whole lot more about how these things work than you can ever know. And there are people here, who know that you don't also know the head and tail of what you speak about.

Nah you don't, you talking BS, you just went to do the research and realize the importance of the torque wrench is and you came back trying to be smart, Nah we not having that, Stick to your conventional ITK and crack on.Oga stick to the cars people give you to sell and stop deriving into stuff you know next to nothing about plz.

Stop trying to sound right.
Is torque wrench important for an engine rebuild, YES. Can you rebuild an engine without it, a resounding YES.
If torque wrench were indispensable as you're making it look, then no one would be changing their tyres without it when it's flat as the wheel nuts are tightened to a specific tension; but an experience hand knows when to apply pressure to the nuts and when not to.
He also asked if all cars from 2015 needs their batteries reprogrammed when replaced as you've boldly claimed and you stylish avoided his question.

Ok well done Engineer with Torque wrench on hand. I wont advice or take any car of mine to any mechanic without
1 Torque wrench
2 Car scanner
Unless its purely a mechanical problem that has nothing to do with pressure or seals. I would be worried about the un uniform pressure both bodies produces .In the case of valve cover and its gasket etc. Not everything is expensive ,its all about doing stuff the right way.
DO I need a torque wrench to tighten my Wheels on maybe not, but we al know its a 100 foot pound. Its a high torque that we hardly achieve with our bare hands. Do I need a torque to tighten my head bold between my Engine block and Top cylinder head, hell yeah and in the sequence designated in the workshop manual.The torque wrench is not the most expenssive tool, 9ja mecho have far more epenssive tools.

If you bothered to read my respond instead throwing your dummy outta the Pram you would have seen two well Enlightening links that warns about what will and can happen if you do not re program your car ECU after replacing a battery.It might be new knowledge to you.

No mechanic will take you serious. Bring your motor make I sell for you too.
Just don't bring that your converted range rover.

And you didn't answer my question on the toyota and yaris. Do they or do they not need programming after replacing battery?

Oya, run off to Google and copy and paste another useless link that does not speak to the question i asked.

Do I need torque wrench to tighten my coolant reservoir cap?

Battery terminal nko? If I don't use torque wrench, the voltage will read less than 12v?

Rest.

I am pretty sure you got the gist. I am not a car mechanic, however I'm a DIY enthusiast and a Fluid Engineer. If you have even a basic Scan tool that can program, you will notice there is a battery and BDM programming. The thing is people like you don't listen and don't learn and everything is a joke to you. Now you are trying to sound sarcastic when you aint even remotely close.
To your question Every car that has a smart charging unit should be programmed if not the charge unit will charge the New battery as if its the old one, this is the simple reason you should.
Personal Experience's cars need a full charge of 12,50 plus V to enable programming fru the OBD port, if your formal battery can only reach 12.10V which is Ok to drive ,your smart charging unit is learned to charge to just that. When you eventually buy a newer battery, its still gong to be charged up to12,10v,so OBD programmer needs minimum of 12.50 Volts to do anything, at this point you wont be able to do anything.
But anyway what do I know sef.Guy good luck

Gradually, you are seeing the error in your ways.
It has now changed to "every car that has a smart charging unit".

I tot you said all cars from 2015?

Is this the same with "all cars in the west are serviced every year"?

Fallacy of generalisation.

And oh yeah, our knees are quaking cos you are a fluid engineer.

Stop it.

Do I have to reprogram my car if I remove battery negative terminal whenever I'm carrying out maintenance, the only effect I noticed thereafter are radio and sound settings erasure, Except I didn't take notice of other things

Ita a digital wrench that beeps with a sound once thw engine bolts are tightened to a certain degree.just few meko have that tool. Once its tight,agh baba e don so quacks believe.

In the context of the discussion, you do not need to reprogram your battery management system (if your car is equipped with one) when you disconnect the negative terminal.
You should reprogram when you replace an old battery with a new one so the ECU commands the alternator to charge it properly.

The truth of the mater is that, I don't even know this and I have own a car since 2015.
I bought a new battery about weeks ago and the only thing I changed was my charging fuse when i keep getting charge error system check . I only upgraded the fuse to 15amp
