I checked with my friend, the oil expert. As many may know, the base weight of the oil is the last number, i.e. 20,30,40,50. The additives package is what takes it down to the 5W,10W or 15W. This explains why an engine may use oil with a "30 weight" but not the "40 weight". While the 5W-40 does have ...

I'm not an oil expert by any stretch of the imagination. I do have a friend that is quite knowledgeable on oils. He introduced me to Amsoil. I have been using it on a diesel powered Jeep with great success. I now use this oil on both of our Volvos ('96 855 Turbo w/212K miles and '99 XC70 w/105K ...

Thanks for posting the question. My newly acquired '96 855 has the same problem with the Driver's Front door. Now, after reading your trials and tribulations, I have more of a perspective on the situation.

I've been told many times that there are no dumb questions but plenty of dumb answers. There ...

Suggest finding a climate control unit from another '93 and see what changes with the fan activity.

Congratulations on getting the old girl up and running. My opinion is to plug in the relay, it's there for a reason. The pink 103 should be fine; it was what I saw on my '96 850 and my wife's '99 XC.

BTW, in what area of the country do you reside?

I assume the hard to remove disconnect (left side) was the one on the passenger side. I too had a hard time until I realized the line was being held in place by a hex bolt. Remove that and it's out. I had a harder time reconnecting it. Doable but you have to contort your hand. FWIW I think the ...

When I changed out these units on my wife's '99 XC, I found that the four (4) through-bolt attaching points on the underside of the dash were prone to cracking and was the source of a squeak. I fixed mine with some JB Weld two-part putty ( the bar in the plastic tube) around the nut mounting area ...

I replaced the evap and heater core on my wife's '99 XC and am gearing up to do the same repair(s) on my newly acquired '96 855 Turbo. Not a job for the impatient or inexperienced technician.

From my experience, if you do tackle this job, bag-and-tag EVERY nut, bolt, screw, etc., from the first ...

Admittedly, I have not read this entire thread. Haven't even scrratched the surface, really. However, given that it has been around for going on five years and has (currently) five pages of responses, I'm sure that there is copious amounts of useable information. Thanks to all who have contributed ...

Oil on the outside of a turbo typically indicates a leak from another place on the engine. How's the flame trap?
