if its not broke...

DON'T FIX IT....

leave the dam thing alone...

don't do engine services unless they've done the kilometres... 10,000 ...

if its using oil over the period of 10K then drop it back to 8K

It's all done. All worked out ok.
Was a bigger job than the '10 minute auto fluid change' as seen on the clip.

A few interesting pts.

I checked the fluid level on the dipstick before I begun.
It was too high I thought.
Got the drain plug out and caught the old brown fluid.
Manual said 3.4 L should come out, I measured what came out, it was 4.3 L.
So there was too much in it.

Put drain plug back in, checked level on dipstick. Good, it was empty, I had drained the right stuff.
Refilled it with 3L of auto fluid. It was a bit low, put 400 ml more in, it was right.

This changes only 1/2 the fluid in the auto. Does not do the radiator or torque converter.
In a car that has had a few kms, and the fluid is not good it is safer to just change 1/2 now. 1/2 again in 6 months time.

All the seals are used to the fluid that has been in there for the past 5+ years and 100,000+ kms.
If you change 100% of the fluid it may find the change too much and leak from a seal.
If you change 50% now it should be ok with that.

It's still a good improvement on what was there.

Well, yes and no.

Modern oils can extend the time/distance between oil-changes, but can't abolish the need
altogether. Years ago, changing oil every 1500 miles was common, AND you'd also have to
change grades of oil depending on whether it was summer or winter. Nowadays changing
needs to be no-where near as frequent, but must still be done, for a number of reasons.

Firstly, oil will deteriorate and absorb moisture and impurities much quicker on lots of short
journeys than it will on several longer ones for the same total distance travelled. So more
frequent changes are indicated, not less frequent.

Secondly, oil does deteriorate over time (although not so much modern synthetics with all
the additives) which is why manufacturers will say something like 'Change the oil at 6,000
miles or 6 months, whichever occurs first'.

Owners of 'performance' and race cars will, of course, change their oil much more frequently
and will also tend to use top-quality oils, but this is false economy in a high-mileage bomb.

Somewhat outside the scope of this discussion, but worth mentioning, is that some oils
(such as brake-fluid) are hygroscopic (meaning they absorb water from the atmosphere)
and so need to be changed occasionally for this reason. Ever dismantled a brake and won-
dered how the hell rust could form inside a sealed system full of oil? That's how.

That's amazingly good.
I've had a few Toyotas and they have been faultless cars.

I guess the gearbox/diff/brake areas don't have the same heat applied as the engine oil does.

You get blow by past the piston rings with combustion which contaminates the oil, the black carbon line below the piston rings on the piston proves this happens,with LPG the oil lasts a bit longer.

As for brake fluid you don't have to change all of it, I just bleed off what is in the caliper until clean fluid comes out,it absorbs water and the brake pistons will corrode if not done.

Did the auto fluid flush this arvo.


All went well and according to how it should go.
Measuring the amount of fluid I drained out was important.
Watching it on utube first was very helpful.

That's  a scary one.

Found this on google for you

Perhaps ring an auto electrician. Tell them the story and what you have googled.

For them to diagnose it is expensive and does not solve the problem.
For them to 'supply and fit an engine harness' is expensive and may solve the problem.

Good luck.
I have got into he habit of 'googling' or 'utubing' for problems like this.
Very handy
