What to know when buying an older XC90 Diesel, please.

Transmission will need to be flushed. Turbo to intercooler pipe breaks the mounting lugs and allows the hose to blow off the turbo. Swirl actuator rods and b...

USA didn't get the diesel XC90's and don't have access to the diesel specific parts.

Ex850R;118754 wroteLovely!
Well done in your search and seeking out the knowledgeable lads here and of course John.

You can buy parts needed from FCP Euro in USA and shipped here cheaper than buying here. Plus, lifetime replacement warranty! Yes! Send them back for replacement and only pay postage, an absolute bargain. John will help out installing the bits.

I am wondering if smaller diameter wheels and therefore the tyres t won't wear as quickly is the best idea?
Shop around for replacement tyres once you need them, keep the suspension fresh and alignments done at a recommended tyre place, not all shops are great at wheel alignments and a good one will tailor the job to suit rather than just to spec.
Wheels off an earlier model perhaps.
Tyre experts can help.
@AshDVS?

Wow, Snoopy/ Ex850R .......THANK YOU! That advice sounds invaluable. I know how much regular tyres have cost over time and was therefore wondering how much these larger ones would be. Much, MUCH appreciated.

Shall copy and paste this to John now.

Just wondering but....the main reason I bought the XC90 rather than the XC70 was for the added height off the ground. I live in the country and having had my lower model Volvos in the past, was rather much over the underside scraping so often when driving out here off road..pot holes, post flood uneven ground etc. Thus, were I to swap the larger wheels of the XC90 for smaller ones, would that not bring me back down lower again or might the difference be minimal? Are the possible variables unknown (wheel diam, tyre size etc) such that in effect, I'm asking a question akin to "How long is a piece of string?"

Thank you again.

They did and they do
I personaly serviced over a dozen d5 cars imported by the sweedish embassy when i lived in the uss previously
Parts were never an issue

Thanks Philia Bear (@Philia_Bear), that's good to know and I'm relieved the USA is not out of the diesel part supply, running stakes. Cheers.

Embassy vehicles would be a different story. Like many places that you now have to supply a VIN to be able to order parts. The D5 XC90 throttle discs 30777650 can be seen on some parts places but not available to be bought.

Vin supply is not an issue when dealing with most places i have worked with
Most of the larger shops have the vin of a canuckistan or south american car to list into the system to game it when required
Ive got no idea about who you use in the usa, but working with fcp and 3 local dealers in the usa i have never had issues getting any d5 parts i have been after

Most of the time though it is simply cheaper to get piles of nos out of the uk for d5 bits though

Or just ordering the parts through volvo penta in the usa

The smaller rims like you have there are more common and harder wearing 4x4 tyres. the 19's do chew tyres due to the profile and need for higher grip performance when using a good qaulity tyre.

I'd personally prefer a tyre that wears out in 30,000kms and 3 years, than a tyre that is ten years old and has done 100,000kms, the abs system goes off to easily, the traction control as well. it just makes a poor driving vehicle. And less safe.

PaddlerEd

The only reason people get 100k out of a set of tyres is they run them from 12mm tread to 1.6mm; realistically they're done at about 6 or 7mm. I've got a set that have done 35000km on the 4Runner and they're going to get rotated onto the trailer to replace the aged tyres on there, still plenty of tread (about 6mm) but are starting to get a bit lose on dirt.

Gulp, in my ignorance, I'd not realised that such a difference in tyres could make such a different to handling and safety which (along with quality and weirdness), is the main reason I stick to Volvos.

In 2001, I had a massive and horrendous accident. But for the tank-like nature of my '83 Merc, I'd not be here today. After that, I never wanted to drive anything but a Merc or Volvo and forbid my kids to drive anything else either. I'll take your advice....if I can confirm I understand it. :)

Vee_Que

Yeah, basically as Ed said also.

Jackiejr

I confess at one stage, unbeknownst to me, I'd been driving on tires whose threads (?) were showing through. I recall the tyre seller being somewhat mortified; as was I.

Terry

Surely you weren't driving on tyres with the steel or textile belt showing - "unbeknownst" is not a word to be used with tyres - regularly check depth of tread, sidewall condition and pressure. Not meaning to sound schoolmaster-ish but that's a basic of any car ownership. That said, what tyres and size exactly are you running at the moment? if you are considering smaller diameter wheels (say 17 or 18 if yours are 19) then you must/should keep the rolling radius the same as original. i.e. if yours are 50 profile then you should look for 60 or 65 or 70 if you go smaller. Otherwise your gearing will change, it may not be compatible with the spare and a whole slew of difficulties arise. Just MHO. Gone are the days when we threw on 13" rims instead of 15" to get a bit more acceleration our of Austin A40s ;) .

Thank you Terry and consider me duly chastened. Motor issues have never been something to which I've paid sufficient attention.
I am working towards reformation. :/

As for changing the wheels for ones that are smaller, I discussed this idea with my mechanic who confirmed the pointlessness of doing this given the only reason I bought an XC90 rather than an XC70, was for the greater height to avoid scraping the underside on uneven ground here in the country and also ease of entry and exit.......I'm turning 103 next month......

In addition he warned me that swapping wheel sizes can affect other functions and so it can bring with a a range or troubles...what I think you too were suggesting.

Many thanks again for the written kick up the posterior. Safety re tyres is indeed paramount.

Oh, no doubt both of your replies came from perspectives of concern. Thank you snoopy.

There are plenty of quick wearing 17's out there
Prior to the 19's I had some 220 tread wear brand name tyres on my D5 and they were dead after 12 months and 25,000KM

17's of any brand are softer and way more comfortable on dirt on an XC90 as compared to 19's
There are zero downsides to moving to a 17" setup on an xc90 outside of road feel (it feels more boat like but grips exactly the same)

Question....unsure if I am imagining this or if perhaps I've not been so concious of it before but my diesel XC90 is far less "smooth" thank I'd expected. Not even sure how to corretcly describe what I've feeling. Maybe it feels a bit more "grunty/robust/gravelly" than I'd have expected.

I've not before driven diesel but could that have anything to do with it? Surely not......

In addition, the indicator noise and frequency of tickies is driving me a tad potty...they seem louder/faster/more assertive than those in my '01 V70. Can anything be done other than learning to ignore them?

Yours in sensitivity,

Jackie

To clarify...

When you change wheel size, to maintain the rolling circumference and radius you change the tyre profile to make it the same overall as what was there before.

So an original fitment larger wheel diameter has lower profile tyre, the new smaller wheel has higher profile tyre which gives you same ride height but more comfort.

May even get cheaper tyre in that size.

Of course you buy the best tyre you can afford.

Ahhhhhhhhhhhhhh...now I understand what you meant. Thank you Segnor Snoopy.
