Breaking in New Car

Postby pete.ryan on Mon, 15 Apr 2019 5:31 +0000

Hi All, interested to see what everyone recommends for breaking in a new Hilux? What does the manual say? Or do you have your own thoughts?

If you ever saw how they test them at the factory you'd never worry about that ever again :shock: :shock:
They sit them on a rolling road and run them up to the redline in every gear with it hooked up to their diagnostic equipment checking for faults

Do you have a youtube of that for a hilux in particular? I've seen them for performance vehicles but never a hilux.

Some components, such a diff rings and pinions, require heat cycling when new. Hopefully most of this is done in the factory or while being driven about slowly during transportation from the factory to the stealership.

You see lots of example of business and hire vehicles being flogged straight off the showroom floor. The problem is there isn't any data that shows these vehicles are still clocking up the long term kms.

Personally, if it was my car new off the showroom floor, I'd be gentle to if for the first 1000 or so kms.

When I bought my 2012 SR5 the saleperson told me the exact opposite from the last post. For the first 1000km, let it rev hard, redline, flog the arse out of it. Did that, drove it like I stole it, never had a problem with it.

I think of it this way, a diesel engine takes a long tine to run in, maybe tens of thousands of k's! Yes they thrash the shit out of them before they leave the factory. A lot of manufacturers go well past redline for quite a while! Also if ya buying a new one wouldn't you rather have it fail while it's under warranty. My two cents, drive it like you plan to drive it. If ya hard on ya gear then be hard on it, if you're a grandpa behind the wheel then drive like one lol. Hope that makes sense.

I'd like to see the evidence on the factory thrashing before I subscribe that.

Some evidence from https://www.nitro-gear.com/category-s/181.htm on diff components break in:

BREAK-IN PROCEDURE:
In order to prevent damage to differential components it is essential to follow the break-in procedure after installation of a new ring & pinion. New ring & pinions will generate more heat initially after installation and can cause gear oil to break down, leading to premature failure. On your first drive, stop after the first 15 or 20 miles and let the differential cool for 20-25 minutes before proceeding. Drive conservatively for the first 500 miles following installation (avoid hard acceleration & towing). After completing standard break-in, tow for very short distances (less than 15 miles) and let the differential cool before continuing during the first 45 towing miles. Change the gear oil after the first 500 miles. This will remove any metal particles or phosphorus coating that has come from the new ring & pinion.

Talk to ex-GMH end of assembly line workers. They caned them on static rollers to make sure nothing went bang. My mate owned one of the first HT GTS350 out of the Pagewood assembly plant and it was crashed being flogged from the rollers to the finishing area, had to be repaired and was replaced by another vehicle for the designated duty it was allocated for. Don’t be surprised if your new Hilux hasn’t been started, stopped, flogged/revved cold up to a dozen times between the end of assembly line in Thailand, to holding yard, to truck/train, to dock, to ship, to dock, to truck, truck to holding yard, to truck, off truck to dealer holding yard, onto truck again to different dealer etc.

That's why the Speedo says 0 when you buy a new one. I don't believe they aren't driven before we get hold of them. Speedo probably is zeroed by the dealer before it hits the yard!

I get plenty of new cars straight off the truck in our shop and have never seen zero on the speedo. I've seen a new ranger with nearly 100ks on it!

I remember an old diesel mechanic was answering questions on the radio once and he was asked 'what's better for a diesel engine, driving hard or driving conservatively?" and he said a mixture of both. He said something like ' the engine will benefit from the occasional heavy load up a hill and the smooth, fast freeway run'.
I must admit mine feels great pulling a heavy load up a hill, its like that's where it's sweet spot lies.

Not sure where you get your info but that’s not at all true. My brand new SR had 73km, I’ve seen another one with 23 and another with 47 or something. Never seen any with zero.

Anyhow, seems that there isn't a answer here yet unless someone chimes in from a toyota factory.

I've seen a few factories around the world, none of them vehicle factories. But each time I see a YouTube of an engine being tested I wonder how much marketing that is. Surely examples like the Nissan gtr engine bench tests are real but for anything so mass produced like a hilux, I think it would cost a factory too much time to do an engine test and it's probably cheaper to do a warranty on the occasional engine failure until you admit there is a design/manufacturer problem (this is pure speculation based on seeing some very efficient factories).

So I guess the answer is do what you feel is best.

Every GMH engine was tested in the Fisherman’s Bend engine plant too. They were started on gas, timing set and then crated for freight to the assembly plants. I imagine Toyota would be exactly the same.

Surely they'd have to run every engine b4 it goes into a car!

When I dyno tested new V12 Merlin aircraft engines we ran them through fast idle to warm them up and then 110% throttle for 4 hours. Don't ever remember one went bang! And they put out 1850 shaft horsepower!

And as for the diesel mechanic I fully agree, they need both hard to bed in the rings and conservative to settle them in fully.

The 'old school' running in is past tense as the new vehicles are usually test bed run in the factory and any damage is already done by the time we drive them.

Wait till you have a random spot check car turn up at your shop. We had one turn up brand new. Over 250km on it. Still had the protective coatings all over it.
Aussie government can pull random cars off inbound shipments and perform testing for emissions etc. you get one of them you know it’s had a hard start to life.

Me personally my 07 I drove like I stole it every day of its life. Was a young guy going to TAFE and we threw it on the dyno with only roughly 3,000 km on it. Ran it through the sequence we had it screaming on the Dyno. Boys were shocked at the stock stats (don’t ask I can’t remember the numbers) and the fact that the manifold, turbo and over a foot of the exhaust was cherry red.
Honestly it was a different ute after that.
It wanted to go and I had multiple people drive it over the years tell me there was something different about it.
That ute never missed a beat I regret selling it in all honesty because my 13 ended up being a [emoji522]
