Hi there,

It was a defective solder under the rheostat, I have redone all the soldering and everything works as new.

Thank you,

For an older car I would go with a 15W-40 Synthetic or 5W-40 if you can't find a good brand in that viscosity. Have always use 15W-40 in CA (45 ~ 100 degrees) weather till I purchased the 98 S70 T5 and had an unseasonably below freezing morning weather and the Turbo did not like it for a few blocks....

Here in Florida when Volvo Dealer Castrol Synthetic was being used in my S80 they put 10W30 out of bottles in and 5W30 during winters. My T6 is a 2.9 and a sister to your 960's six. Once I switched to Redline oil I use 5W30 year round without issue for several years now. I would not run XW40 unless ...

For all of you near Tampa FL this car came in the yard on 11/8/19 https://www.lkqpickyourpart.com/locatio ... 0/recents/

An oil with a smaller span between cold and warm viscosity is in theory more stable and thus able to resist heat better long term. In practice I suspect it varies quite a lot. I would go for 5w40 regardless of conditions since it's easy to get hold of, covers everything temperature wise and provides...

Last post didn't take. I found my 960 did not like 15-40 during these cold Kentucky winters. Car would start up rough and run that way until engine was fully warmed up. Changed over to Castrol 10-30 and starts up smooth below freezing. Don't know the last time I that low a weight of oil. It's gotta ...

The rear window sunshade was electric on mine. It did not need any fastening. June

The white engines are all about tight tolerances and they hold those bearing clearances for a long long time unless the engine is not serviced or run with low oil level or no or low oil pressure. The crankshaft and block bearing recesses are measured and the selective bearings are the ways that is a...

That is my concern, too with switching to the 15w-40, dm635. We don't get cold that often, but we do have several days a year when we're into the teens and twenties, and those are the days I'd like to take the 960 out. I really do appreciate everyone's feedback on it. -- Simplify a bit and it gets ...

I just joined, picked me up a 98 V70 GLT AWD back in July. Its 428 - Coral Red Metallic in color, with 3980 Taupe Leather interior, it had 232,700KM when I bought it, now has just over 237,000KM. I bought it with a bunch of oil leaks, I thought it was just one large leak, but turned out it had 2 lar...
