TRYGO:
Toyota, and other auto manufacturer's employ the use of basically two types of battery chemistries for use for electric propulsions(to drive their various electric motors).
One of such chemistries is nickel metal hydride batteries.
Their capacities are dependent on the the strings of cells arranged in series, nature of electrodes and manufacture of such.
They have a high energy density, and can safety go through several charge/discharge cycles without posing a fire hazard, unlike their lithium ion counterparts.

These batteries are arranged like a stalk of matches in a match boxes in series, and BMS(battery management systems) are designed to monitor and control currents, temperatures, and voltages, pumping in and out of the high voltage battery.

On highlander or Rx hybrid, Prius, and Camry vehicles, various capacities are allocated to these batteries, depending on the applications.

In the picture below is a battery pack for a high lander or Rx hybrid.

Specification:
Has thirty 9.6-volts modules containing 8 cells/module for 240 cells total (nominal 1.2 volts/cell) provide nominal 288-volts, and a capacity of 6500mAh.

Individual modules cannot be replaces as found in Prius and Camry vehicles, because all modules on the highlander packs are stalked and permanently tightened.

In an event of failure, its always better to have the pack replaced, or get some of the pack of stalked modules replaced with another of matched capacity.

TRYGO:
The main purpose of writing this piece is to intimate people that, asides Toyotas, and others, HONDA BRANDED vehicles can be rebuilt, to standard.

There are a lot of skepticism about engine overhauls.

Some people, see it as a waste of time, and resources. They argue, why not just replaced an engine that's having a major mechanical problems, such as seizures, or engine knocks, etc.

Almost everything on an automobile, can be repaired, without entirely replacing it.

In this piece of writeup, I'd be sharing my experiences on the overhaul of a Honda Accord, 2008.


CASE STUDY

Vehicle: Honda accord 2008
Transmission system: Automatic
Engine configuration: 4cylinder SOHC
Engine capacity: 2.0L

CUSTOMER'S COMPLAINTS
Engine makes a knocking noise; vehicle can't ascend hilly terrain; engine oil consumption is significantly high (he keeps topping it almost everyday).


THE FIX-INSPECTIONS
1. Blue smoke coming out of the exhaust tailpipe.
2. Confirmed engine has no compression enough.
3. Engine make was an R series lineups, which were incorporated in Crv, civics(2013- present), and accords(08).

These R series engines from Honda corporation are in 1.6/1.8/2.0L configurations, with the 2.0L, meant for performance, and fuel economy.
The 1.6/1.8L are basically meant t for fuel economy.
4. All spark plugs were caked, as a result of excessive engine oil burnings.
5. Scoured crankshaft, crankshaft journal and camshaft bearings.
6. Excessive worn camshaft top cylinder journals, and a rocker arm assembly.


*******
1. All piston rings, metal bearings for the crankshaft, and camshafts were all replaced with new genuine Honda only parts.

2. During such rebuilds, endeavor to have all the rubber seals(O-seals, crankshaft/camshaft seals replaced).

3. Ensure the top cylinder and engine block surfaces are not warped(bent).
That would prevent pressure leaks during the compression strokes.
Get a machinist to help with checking that out before assembling the engine.

4. Don't use synthetic oil to break in the rings after overhauls.
I use 20W-50 to get the rings seated properly, then after a month or 1000miles, I get the engine oil replaced, and switch to its recommended engine oil(5w20).

Note: Allowing the engine to idling excessive for a long time, those nothing to seat the rings properly as some mechanics are meant to believed.

Allowed the engine to idling for a while, then go for a test drive.

Simulate all driving kinds of conditions (aggressive, and in gridlocks).

5. Hand over vehicle to owner, and request that vehicle must be returned after a month, for engine oil change.


Finally, if you got any vehicle/engine to overhaul, please get across to the contact below.

It doesn't matter the engine configurations.

Whether, I4, V6-V12.

There are clients over here that we'd had their vehicles rebuilt(a Corolla is still in service, after 2017).

PS: Give your mechanic time to rebuild your engine; don't rush them(him).

uchman:
House please what is making my steering to fall to one side? ve already changed Steering rag, did alignment too...
and
Why do my car slows up while climbing hill?

Please help house...

alakrity:
Pls can someone tell me is it advisable to buy 2005 ford escape jeep compare to corolla car in terms of fuel consumption and durability

AutoElectNG:
Time will tell if the due diligence I followed was faulty.

Secondly, America sets so many automotive standards that the world follows.

Think OBD II for example.

Think of the California's Bureau of Automotive Repair.

Think of the standards for collision repair in the Americas.

I too have undergone ASE education.

So I will naturally gravitate towards the American way of doing things.

I think we would benefit more if we did not fight radautoworks but tried to learn from her

For the academically inclined among us:

Ignore America or more accurately California's disproportionate influence over the automotive industry at your own peril

There is another important paper worth reading it is entitled: "The road to 2020 and beyond:
What’s driving the global
automotive industry?" and it is published by McKinsey&Company, look for it and download it with your favorite search engine

Will we also fight Egunmogaji if he were were to post about his methods here?

Or are we fighting raduatoworks because she is american? Or because she is no technician but a knowledgeable nonetheless? Or she is a woman in a man's world?

Or is this a turf war in the making?

Parting shot: The automotive market is a global one not a local one, in plain language, we don't set standards, we follow them. We have a choice to be a local champion or an international star, I would rather be the later, and it begins and ends with the standards we choose to align ourselves with, whether they be local or global.

This evening i went to a car wash to wash my car. After which i returned home. And then i switched off the car and the car's engine refuse to go off but all other electronic in the car went off(radio,engine fan etc). So i removed the battery and d engine went off then i tried starting it again and then it refused to start after inserting the battery back. What could be the problem here

FAFS15:
greetings house, pls I need ur assistance my nissan sentra 02 sometimes slow down wen climbing hill and wen on traffic. wat might b d cause?

m4goodlife:
Hi peeps, I'm thinking of changing my car Honda to a better budget efficient car. Ordinary I would love to go for a Toyota but my budget right now can't afford that. I'm thinking of going for nissan altima 2001 model, but I rarely know much about the car especially its maintenance cost and how fuel efficient it is. I will appreciate an honest review of it. Thank you.

Nefo:
It's not about our environment. Hybrid cars are good and saves a lot on gas. The problem is that we don't have skilled technicians that can fix the problems.

radautoworks:
Chim oooooo!!! That's exactly what the mini-course are to avoid. So they at least know the difference between oil, coolant etc. You think it catch on?

The teenager class is something my husband really wants to do. That's how he started out in Jamaica. Same challenges then. Mechanics had no respect and it was looked down on. Noone considered it a viable option. People don't know how technical it actually is. Not everyone can be a lawyer, doctor or engineer. This is a good career path for a lot of people. If a child shows interest, it will be a good foundation for them to go on from.

In Houston, we actually took on a pair of brothers for a year. Today, one of them is a tech at a Nissan dealership and doing excellent for himself at age 17. The other helps out every once in a while with his nephew's repair shop but chose a different career path.

agabusta:
What of engine and transmission mounts?? Can't they also be responsible for shaking and vibration?

yagor:
I have this small scanner we connected to the OBD port or what is it called?

The scanner comes alive and says "waiting for vehicle to respond" .

well vehicle cannot respond because ignition will not turn on.

GAZZUZZ:
80,500 is ringing in Uncles head as he slows down and calls dipo.......

he places a call to dipo.

Eng dipo! The light is back o! Just as I left your shop it came on o! This thing did not work...... The phone cuts off with dipo not saying a word.

Uncle comes to Nl to report dipo

EgunMogaji:
I wouldn’t personally call Ikenna a great man or put him in the same high table as Siena but I’m sure he won’t loose sleep about my opinion of him.

CarTalk is actually a great place and not one person makes it great. It’s the cacophonous colourfulness, rambunctiousness, as well as occasional effronteries that makes it palatable

EgunMogaji:
I’ll like to think that Gazzuzz was simply caught off guard on a bad day. We all have some days like that when we don’t have fuxs to give.

But when you advertise a number as a business venture then you ought to expect all kinds of people to ring you up.

Sometimes I get calls at 2AM here from Nigeria, some I let roll into voice mail when I don’t recognize them but the ones I decide to answer is answered politely even if it’s to fake “busy with a client on the other line” and let me get back to you.

But I’m coming from a country where customer service can make or break a company.

I’ve never met Gazzuzz in my life but I consider him a friend so if I call him I’m certainly going to not be officious. If he cuts me off I’ll just go camp at his shop and consume many beers and “Ofe Owerri”? as apology.

The manuals make everything really slow for a first time as you have to follow the procedure to the later which takes so much time but I am sure we would get a hang of it

Of course it does...for optimum combustion.

Please experienced men in the house kindly advise me

The kickstarter on my '04 accord was replaced today and now the vehicle cranks but will not start. The mechanic and rewire say it has entered 'code'.

Please what does this mean and what should I do next?

AutoElectNG:
Toyota is not complex...Toyota is simple...the automotive industry is a competitive one...Toyota cannot be left behind...if others go techy...Toyota will go tech...Toyota will not go tech...Toyota has gone tech already...Give your state-of-the-art Toyota's to roadside repair shops at your peril.

Read this link https://www.collisionrepairmag.com/sponsored-articles/20070-future-of-repair from the first word to the last word and then tell me if it is not suicide to take your 2018 Toyota to a roadside mechanic who is not aware of 10% of the new technology in a Toyota.
