Good to have you aboard Robert.
Many on here swear by your how-to videos on YouTube.
I especially liked your vid on bonnet replacement. The trick of pegs in the springs to hold the tension is just pure genius, my friend!

HD:
I'm interested in your XC90 'cooler. Looks spot on.
Any write-ups on fitment, year/engine they're from, etc?
Do you use a thermostat, also do away with the in-rad cooler?
Definitely need to look at a decent cooler now I'm putting nigh-on 300 horses through my 4-spd, especially launching it up the 1/4 mile. Been on borrowed time for a while now!

Hallelejah!! Someone on my wavelength - At last! It took a Yank. And a Yank simply because like me, he's actaully done it. I mean actually driven his car.

Brits as a rule don't drive. Ask a Brit living in the SE of England to drive to Glasgow and he'll moan it's a long way. He might go down to the West country, (Devon & Cornwall) once a year on his hols. but that's it. 500 miles is 'long' way.
So he puts on go-faster bits etc etc which kinda admits he owns a car to park it. Because that tosh'd soon get on his nerves if he actaully did drive the thing.

To fellow Brits: Believe me, a Yank thinks nothing of a 4-5 hour drive - he has no choice. Many drive cross-country at 3-4000+ miles all in. Go on eBay.com (the Yank site) adn look at their galactic used car mileages!
Those Hollywood movies set in Motels are set in Motels because they exist. Now ask why?

Robert, here we routinely throw these cars away at 150-200,000 miles so most won't have the first clue what you or I are talking about. In fact 200K pretty is rare to see. Most hit the breaker's pile at 130ish because of minor issues and loss of snob value.

You know it, I know it, fresh fluid is brown by 40,000. The box will still run OK and even do another 100,000. But by 80,000 it's black and starting to chew into the box. But average Brit driver won't see or notice it, because at Brit miles (say 10-12,000 a year) he'll not notice the decline or will have changed his car before the next flush is due. And the last owner puts it on the pile.

You can get away with only doing frequent flushes, but at Brit miles, that's only every 3-4 years, so far from frequent at all. The thermostat is perhaps overkill, but I did it anyway yet, my caveat stands, if you drive it, you'll need a cooler. I drive mine and I tow. But the cooler is there in spite of, not because of the towing.

And I've got £500 that says if you car has fluid over 40,000 it's brown, if over 80,000 it's black and chewing your box. At the very least flush. Magnefine of course.

But now I'm repeating myself.

Thank you Robert. And thanks for the vids - must take you forever to do.

Just one point to note. The red is dye. If does fade with use. Brown ATF is not necessarily compromised. Smell testing, and or blackening are evidence of either thermal degradation or contamination, but let's not make out that ATF not being cherry red is NECESSARILY a problem.

I ran an S70 auto for 10 years, and whilst I can't lay claim to intergalactic mileage as some in the US drive, I did drive c 200k miles in that time, and included ATF changes as part of my servicing rationale for the car. When we parted, it had around 280k miles on the clock, and the engine and transmission (both original, both regularly serviced) were both strong, reliable, and showing no evidence of being anything other than completely servicable.

The transmission exhibited no apparent slippage, harshness or anything untoward, and I saw no degradation to it's behaviour from start to finish. From the perspective of engine and transmission, I would say that both would have easily taken several more 100ks of milieage with no detriment.

Robert, your videos are awsome. Helped me out loads doing my V70 up.

So I have a V70 auto with 181k on the clock and I am going to try to keep this going for as long as I can. I lack the ability to add a cooler myself or manufacture anything. What do I do?

Like CNGBiFuel said, I do drive. I live in Belgium and my driving is a lot around town to shops, schools, kids activities etc but then ever so often, I'm off to Sweden to see my mother (2000 miles round trip) or Spain or Italy on holiday and frequent day-trips to Germany etc.

I have the old accessories catalouge for these cars and Volvo did offer a cooler, is that something to consider?

Agreed, but left mine goes black, and my bet stands. By 80,000 I've not seen a car that shows anyhting but black ATF. Not an issue in warranty miles - Yadda, yadda...

This was answered in my thread, and again by Robert.

The S70 I had, had 80k miles on it when I got it (it was 3 years old, I drove a further 200k miles in it).

The ATF in that wasn't black. It was brown but not "dirty" brown. That's when I started changing the ATF but I did that as preventative / pre-emptive thing - not because there was a problem, nor that the ATF looked problematic, more that I wanted to get the most out of the car from a longevity perspective.

And in my book, that's Boy-Done-Good. The perfect way to deal with it. At 80K that fluid would be getting tired, but likely still OKish. You flushed it about right. Being objective, left alone, you might well have got away with it too... it is possible.

The guy that gets 250,000 out of his fluid and engine oil, twice over, will be along in a mo'. Speak to Lakes of Wyboston and why many of those cars are on the pile, not all are there with Trans issues, just a lot of them. For the rest of us, fluid looks cheaper

when i got my mine it had done 190k and the fluid was very dark indeed, ive done 14 sump dumps on it so far and on the last flush it was the same colour out as i was putting back in , thats with 100 miles between them flushes.

plan is to drop the sump on it every time i do an oil change or at least every other oil change to keep the fluid fresh , bonus with mine is its non turbo and doesnt tow anything so hardly gets driven hard ,

interesting reading through this though......

OK. Only you've missed my central point. Towing as such, or how heavy your right foot gets, has no bearing. How did you think your fluid got black?

If you've done 14 dumps, do the maths, from memory, there's 8L total, and each dump drops 3L, so work it thru' and you'll see how much the old ATF is now diluted. A helluva lot. Should be pink.

Are you sure you've done 14?

14? Really?
14 x 3L = 42L

Unless yours is hte earlier 4-speed box, not needing it, 42L of JWS 3309/ Toyota iV has cost almost a new box anyway
About 15L will have it Dark plum, if black before. 18L shoud see it looking Dark Rose Pink as against fashion shades of light Rose out of the bottle. Magnefine it. If I recall right, 3/8" on 5 speed. 1/2" on 4 speed.
