What did you do to your Volvo today? Topic is solved

[foggydogg]

Did combat with the torque rod bushing, 9434263. After intense negotiations, and finishing with the Large Hammer, it yielded.

And the warning Robert sent out some time ago still holds true; the Meyle bushing is too small, and rattles around in the bracket.

Did you rotate it 10 degrees forward as recommended by Volvo!??

So yesterday, in the blistering heat, I changed the timing belt, waterpump, tensioner and "looprol" (don't know what that part is called in English). Everything went smooth, cars runs like a charm. There's this thing however, that bothers me. What is the actual interval? I've got a Haynes manual suggesting 120.000 kilometers or 8 years. I've got a Volvo dealer that suggests 165.000 kilometers or 10 years. And when I searched MVS, I even came across someone mentioning 75.000 kilometers or 5 years. Okay...

My S70 has a 2.5 liter, 10 valve engine from august 1998. Enginecode B5252S. If someone would shed some light on this, I'd be very greatfull!

I have always thought 70,000 miles was prudent for our 20 valve motors ( around 115,000 km ? ), but I don't have an owners manual with me at the moment. Given the relatively small price for the parts, and the large price for a disaster, it probably isn't worth the wager on going more than ten years. The Volvo dealer is presuming Volvo Blue Box parts are used; your 10 valve non-turbo motor may be a bit gentler on the valve train.
Stay hydrated in the Tropical weather that has descended over you now, fall is coming.

75,000 KM seems too soon, 75,000 miles is a little more realistic. That was the initial recommendation on earlier cars, however the later cars (1999-2000) recommend either 100k or 120k miles (160k KM) or 10 years.

Time to look in the Service interval section in the manual. We don’t get the 10 valve car in the lower 50 provinces, the change from 75,000 miles to 105,000 miles intervals happened in mid 1998 with the change from hydraulic to mechanical tensioner

Ah, so that's the difference. I have not had the mechanical part in hand, but from pictures/video describing how to adjust it, I've been glad not to have it. The hydraulic seems to work fine to me. In fact, the original I removed from my car seems to be in decent shape still.

I assume you've had both abscate, do you have a preference?

[bmdubya1198]

The hydraulic tensioner seems to last longer too, which is why I find it interesting that Volvo extended the service interval with the mechanical tensioner. The pulley itself should be changed every timing belt service, but the hydraulic ram tends to go forever unless it's leaking.

I prefer... the one that fits on the car. Its not a choice we make, the block is machined with holes for one or the other, at a chassis break.

It might be the temperature compensation on the mechanical allows a better set on the tension leading to the longer service life - or it might just be that the data supported a longer life. I would guess the latter. I ran my own experiment running my RN to 140k/ 14 years on its original belt, idler, pulley, and tensioner.

I'd rather have the hydraulic tensioner, purely because it takes 0 thinking to install the mechanical one is a bit fidly
