The Dreaded 100,000km Service

[Lawson]

It happens to ever Supra at some point, everyone knows about it, most are scared of it: it’s something that’s only talked about in hushed tones … it’s the dreaded 100,000km Service Arrrrrgh!

If you'd like to talk in-depth about my experience getting the 100,000km service, then PM me and I'd be happy to call ya.

I thought it was about time that a comprehensive write-up was done on this subject, and since I’ve just completed this service I can speak from fresh experience. I must firstly appoligise for the lack of photos in the write-up, but my camera died on the day. I will be teeing up with Carlos from Millennium Motorsport to take pics of the next Supra they do a 100,000km Service on and add them at a later date.

Step 1. Planning
Since no Toyota Dealership in Aust has really taken on the role of master parts importer like Elmhurst in the USA and Rutherford & Bond Toyota in NZ, planning for this service is the key to it running smoothly. These two dealers have most parts in stock, but if they don’t it’s a 10-14 day backorder from Japan (and that’s to their address not yours). So give yourself at least 3 weeks grace from the time you place your order until booking in your car at the workshop.

I used Rutherford & Bond Toyota in NZ and my contact was Rory. This guy is not only an accurate parts interpreter (not one item was wrong) he’s fast on replies to your email enquiries, will call you back straight away when asked, pricing was fantastic and just quality customer service all round. I highly recommend him for all you Genuine Toyota Parts.

There are basic things that are replaced in the 100,000km Service such as timing belt and drive belt. To access these parts requires removal of a fair bit stuff off the front end of your engine costing you labour time. So take time to see if other wearing components should or need to be replaced at the same time (like water pump, front main seal etc..). This will save you in the long run on labour costs down the road. Therefore I will discuss both the budget approach and also the comprehensive approach to this job. Believe me, you’ll get what you pay for, so if your approaching 90,000km I’d suggest putting money aside for this service … it’s not a cheap one to do comprehensively, but will save you heaps of $$ in the long run if you’ve invested the dollars at this service.

Step 2. What Parts Do I Need
Please note all your fluids are replaced at this service, and besides the 6speed gearbox oil I will not be quoting what to use.

These are the fluids that will be replaced:
5L+ Engine Oil (Fully Synthetic Oil)
1.8L Gear Oil (ONLY Genuine Toyota V160 Oil) (08885-01306)
1.65L Diff Oil (SAE 90)
2 Bottles Brake Fluid (DOT 4 or higher)
4L Power Steering Fluid (Automatic Trans Oil Dex III)
Brands of engine oils and such are a personal choice, by how much you want to spend for brand names, and your own experience. Your best guided by your trusted mechanic who’ll have them on hand.

Here’s the basic list of parts that must be changed at the 100,000km:
1 x Harmonic Balancer (13407-46020)
1 x OEM Drive Belt (90916-02310)
1 x OEM Timing Belt (12264-46010)
2 x 1L Bottle V160 Gear Oil (08885-01306)
1 x OEM Toyota Fuel Filter (23300-49195)
1 x OEM Toyota Oil Filter (90915-20004)
6 x NGK IX Iridium Spark Plugs (BKR6EIX-11)

Here’s the comprehensive list of parts I used for the 100,000km Service:
You can pick and choose from what’s listed here. Please note though, every part I ordered needed replacement either straight away or in the very near future, and if your car has done the same km’s then chances are yours will too. So you can either buy them now and save on labour changes later, or wait and pay more to do it later.

1 x Crankcase breather hoses front (12264-46010)
1 x Crankcase breather hoses rear (12263-46010)
These often are rock hard due to the heat of the engine and will crack when removed to replace your spark plugs.
2 x Cam Seal (90311-40020)
Mine had just started weeping engine oil, and are easy to replace while the timing belt is removed.
1 x Front Main Seal (90311-46001)
Very easy to replace while the Harmonic Balancer is off the car. All though mine was fine the labour charges to remove the balancer in the future far out weights the cost of the seal.
1 x Timing Belt Tensioner (13540-46030)
This is a part the LOTS of people skimp on, but is very import. It maintains a contant pressure on your timing belt. There are two parts to this tensioner, the gas tensioner and the tensioner pulley … HIGHLY RECOMMENDED you replace both.
6 x Coil Harness Connector Housing (90980-11246)
Again these get hard and brittle over time and often break when removing them from the coil packs. Chances are you mechanic will not have them on hand, so best to have at least a couple of these handy … I just replaced all of them.
1 x Water Pump (16100-49846)
If you water pump has never been replaced then you’ll want to do it now and save yourself extra labour charges in the near future. Plus when they do start leaking the red coolant makes a horrible mess.
1 x Drive Belt Tensioner (16620-46070)
This is an expensive part from Toyota and is only need if the spring in the tensioner has lost it’s force. You will have to replace the bearing in the pulley wheel. If you have a metal pulley wheel then the bearing can be pressed out and replaced; otherwise you’ll need to replace the plastic wheel.
1 x OEM Thermostat (90916-03093)
Crazy if you don’t replace this as it’s a cheap part and vital that it works properly.
Or
1 x TRD Thermostat (16340-SP020)
The TRD one is MUCH more expensive but opens 10degs cooler ... a good idea for hot Aust summers IMHO
6 x Coil Pack (90919-02205) (these include the rubber boots)
If money is no object and you want the very best for your Supra then buy these. New coil packs ensure a nice strong spark. Also two of mine had cracks in them which eventually will cause earthing to the block and miss firing under heavy acceleration.
1 x Rear Main Seal (90311-90006)
Again, if you want all your bases covered then get your rear seal replaced as well.
1 x V160 Yoke/Control Assy (33570-14070)
2 x V160 Yoke/Control Upper Bush (33546-22020)
These holds your gear stick rigid, help in accurate selection of gears and stop it becoming sloppy – the bushes in the assembly are not replaceable and mine was completely had it. If you hate sloppy wobbly gear sticks then I’d recommend replacing this item.

Step 3. The Service
If you live in Brisbane, then the only place I recommend is Millennium Motorsport. I spent the entire day with Darren and Carlos as they worked on my Supra in order to do this write-up, and let me tell you, they are perfectionist and passionate about Supras. They know these cars inside out and have the experience to guide you if they find unforeseen parts that need replacing. Also they have cable TV to watch while you wait … bonus!

That brings me to my first point about the service day. Budget some money for the unforeseeable. Things like radiator flushes/replacement, fan clutch, rotation sprocket etc… All these could be on their last legs and once inspected by your mechanic may need to be replaced. Budget to have at least $300 bucks minimum for the unseen, then you won’t have you car sitting at the workshop waiting on you to come up with the bucks. Personally I needed to flush and recap my radiator which I hadn’t planed on doing.

I booked my car in 2 weeks in advance, do this guys! It helps the workshop plan that day for your car, as this is a service can take many hours. Last minute booking means that a mechanic may have other work on at the same time as yours, and they he may not be able to focus on your car exclusively. Explain to the shop everything you want them to do, especially if your like me and want to do a take this opportunity to do some preventative maintenance as well. It's no good telling them it's a 100,000km service, and then rockin up with boxes of parts you want replaced at the same time. Good workshops are busy places, and you may have to forego some work if they are unaware just how much you want done on the day. I also called up Carlos the day before to confirm the booking and time they wanted me there, always good to double check that some emergency hasn't popped up with a clients car they need to working on.

Ok, so I rocked up at Millennium Motorsports at 8am on the dot ... be on time. Nothing worse to start the day off with then you turning up late for your service, and a workshop with mechanic standing around like spare parts waiting on you. Start the day on a good note and be then at the agreed time.

Footnote: It always rains on the days I get work done at Millennium, and last Thursday was no exception :P

I popped the boot and pulled out a HUGE box of parts, and poor old Darren knew he had a big job on his hands *heh*. He also commented that it was great to see someone doing preventative maintenance and not just the bare minimum.

Car was put on the hoist and engine oil was drain, coolant drained and diff oil drained. Diff Oil was then replaced with some 'You Beaut' Motul stuff and the car was then lowered to the ground. Darren then removed the radiator to get more room to the front of the engine. Here's where the unforeseen in my service happened ... the radiator had about a foot of leafs that had half turned into garden mulch around the bottom front of the radiator, not to mention a couple of bird feathers and other assorted fauna :eek So Carlos rang this contacts that do a full radiator service, and they told him they had the end caps for the radiator if needed to be replaced as well, so within the hour they where there to take it away.
The first item from the engine was the drive belt. Man! I didn’t think it was as bad as it was. I’m embarrassed to say it wouldn’t have lasted more then 1000km before it would have failed. Darren just laughed at me and said, “Well, you got your moneys worth out of this belt” No worries now with a brand new belt on the old girl.

The Drive Belt Tensioner was removed next and the pulley wheel bearing was checked. If you have a metal pulley wheel there is no need to replace the whole wheel as the bearings can be pushed out and replaced; but unfortunately mine was the plastic type which can’t be overhauled. Being a 1993 Supra I thought for sure mine was a metal one, as metal pulleys came out on the early model MkIV’s, but it appears that mines already been replaced once by a lazy mechanic in past who didn’t want the hassle of replacing the bearings and just order a plastic wheel Being a TT engine the Drive Belt Tensioner also has a little shock absorber which was also checked and was fine. Darren said that if they are stuffed they are rarely replaced, as they don’t really serve too much of a purpose, and just the typical over engineering of the 2JZ.

Then the Balancer was removed with a special tool to break the nut loose from the crank. I have no idea how someone with the a standard Sidchrome socket set would even budge this nut ... it's on crazy tight and needed to be put back on crazy tight to avoid damaging the keyway. After removal the keyway was inspected for wear, and mine was perfect, and the Balancer was inspected. As expected it was at the end of it's service life and needed replacing. If you take the risk and don't order one for your service, this could be where you day ends until one can be ordered in. This is the reason I included the Harmonic Balancer as part of the 100,000km necessary parts. There is a very high degree of chance you'll need to replace this item then and there, or in the very near future, meaning added labour costs to you. In the long run if you don't replace it at this service, you will in a short time. If it fails and damages your crank, then say goodbye to thousands of dollars as the engine will have to be torn down to repair the damage or a replacement engine purchased ... not worth it boys and girls. Do it at the 100,000 mark, or roll the dice.



More to write but ran out of time ... stay tuned for this post window to be added to

Holding this post window for cont of write-up when I get the pics in the near future

[Anthony B]

Just in time my supra hit 100000km today = (

[Inferno]

Any chance of getting the prices you paid for each of the parts added to the first post? Otherwise great write-up !!

[Lawson]

As I'm hoping this will become a sticky I haven't put up pricing as it will change over time and $AUS rate. You can simply email Rory at the address provided and he'll get back to you same day

[98SZR]

Great write up mate, stick and FAQ ftw, this will be great to point all those newbie's too when they ask what needs to be replaced.

I've got a few pics of this sort of stuff when I did mine but your better off getting a new set as mine were just water pump/timing belt/tensioner pics.

My experience with that Toyota dealdership hasn't been all that great, it takes ages for Kevin to quote you if he does reply at all and most of the time the prices are more than what you can buy the parts for here....

I didn't go through Kevin, I went through Rory and his prices where excellant ... especially when you take into account the exchange rate of the dollar
