D5 Engine. Maintenance that must be done. Pt1.

Ex850R

Community service advice.

Take note, a D5 should have the auxiliary drive belt replaced before 90,000.kilometres or possibly 5 to 7 years depending on climate.

Having today seen the belt that came off a sub 90k motor of 2007 build and its condition I say this, ignore doing the replacement and check of tensioner and alternator at your peril.
Damage that will result from failure of this belt is usually engine write off.

Video of a running motor with worn belt at sub 100k it was obvious this should be a regular maintenance check.

My local shop has been replacing engines that have self destructed at less than 120K then 100 and now 90K so is recommending customers do belts, tensioners and alternator checks at 80K.
Pix of shredded belts are scary. The cost in labour never mind a replacement motor isn't heart warming.

Have the gearbox fluid changed while you are at it..

Volvo dealers were quietly replacing the tensioners on these pre 2010 models. It's usually audible when there's a problem so most people would have to be ignoring the noise for a few months to lunch the engine. Good advice though

Chris

Yeah Berry did my aux belt but still say the timing belt is good at 10 years old but low K's

Whilst the belt looked a bit tired, it was only when twisted and light could be seen through it that it was obvious it wasn't far off launching itself into smithereens.
An $85 belt, saves thousands.
Tensioner ok for now.
All will be checked next service, which by the way will be at 6 months maximum or 7 to 8000k for oil and filter for sure.
Swirl mechanism to be checked and replaced as needed, suggestions of 40,000K intervals?

Anything else we need to look at?

Is an auxiliary transmission fluid cooler needed?
External fluid filter for same?
Thanks dudes.

If you can keep the carbon build up to a minimum with regular oil changes, occasionally giving it a wot run once it's warm, and some decent long trips then the swirl flaps should last a while.

I've had a couple put in front of me now with religious 6 month oil changes (sub 10k km) and the swirl flaps effed
all of them with sub 120k km on the clock

Swirl flaps were always a bad idea on a diesel and the industry has moved away from them for good reasons
I tell people with the D5 now that just budget for cleaning them and the egr once ever 100k km/7 years and its really not much of an extra TCO on the car cost (timing belt at same time)

I've seen lots of 07 timing belts fail at sub 10 years, they looked fine until they delaminated
The cost of replacement of a head and effort at > $4k easily argues for replacing the belt early at 7 years

Chris

I don't disagree; I ask them every time the car goes in (6 monthly) and they keep saying no :worried:

Damn, just thought! Should have gotten the timing belt done.... 89K on it but age factor.
Maybe Pt 2 of D5 threads is, Do timing belt...
I knew trying to write this was no good when tired. Real tired...
Missrs won't be happy not having her car, must wait till mine arrives as the old camry ain't much chop. And, great that they provide a loan car is, it's still a smelly 850...

Yeah inspection at 10yrs might look ok but usually 11yrs old shows signs of cracking/delamination on close inspection. Unless they're gonna supply and fit a motor if it snaps I would push them to do it

Chris

To be fair, they have looked at it, I make sure they inspect it every time. I was thinking its 10 years old next service so time to get it done

Ghettobird

Take it elsewhere then!
We have done a heap in the last year and a bit, some were real nasty looking :(

So these concerns are specific to the D5? (Of which I know little, other than some UK owners claiming starship mileage with no issues).

I understand the (C30, V50, S40) T5 has a 10 year and something like 160K KLM interval. My 07 V50 has only done 80K, so I feel perfectly happy taking it out to say 120 K and 2-3 more years. The only reason I'd be concerned is if the 160K interval was grossly incorrect in the first place (I believe a humid environment may justify not stretching the years of service on a belt, but I don't think Syd would fit in that category 90% of the year).

Ex850R

You may be perfectly happy until the thing breaks.
It seems that so many of them do break.
My shop is replacing so many motors because of this. Buying wrecks with good motors, buying written off cars with busted motors and making a good car out of the two.
Anecdotal evidence suggests it's a good idea.
It has been smart thinking with earlier 5 cylinder motors to replace early so why not now?

Im actually a bit annoyed I didn't think to do it when we did the other belt last week.
Honestly a bit worried too... Am sending it in for a cam belt and further transmission flush as soon as possible.

I get being cautious and proper maintenance etc. What I don't get is why Volvo stipulates a stupidly high KLM interval in the case of the T5 (unsure of D5 KLM interval). So in my mind if it's 160 K KLMS (T5) and I've done half that I shouldn't be concerned just because I've reached the ten years (within reason). These things don't have Calendars built in them so if ones to break at 12 years and say 90K on it then i believe it's even more likely (IMO) to break with 150K on it at 9 years when Volvo's interval hasn't been reached.

Did Volvo get it right with these long change intervals or are they just silly?

its not the timing belt, its the serp belt that people never replace
the serp belt can take out the timing belt on these when the serp belt/serp belt tensioner fails in specific ways

Timing belt....
shit tons of people who just never do them or only go by KM instead of KM or age
My vote is still for 7 years/100k km
The ONLY reason the belts got pushed to 10years/100k miles was California emissions law requiring warranty/free servicing on anything emissions related... some people won a case saying that the t-belt was critical emissions stuff
This is why we have 100k mile coolant and 100k mile spark plugs...

Ex850R

Must get the video off my shop of the serpentine belt all out of sorts needing to be changed.
