Volvo still stocked the Nivomat for my 2004 XC90 when I bought them last year. Not cheap. If you have Nivomat, you must replace with Nivomat. The spring rates are lower for the Nivomat, so if you...

There is no harm in pulling fuses and disconnecting the battery...but also, no benefit. There will still be stored codes. I would get a decent copy of Vida - I think I paid $100 for mine, including...

If it’s better with new fluid, then you’ve done well. Drive it for a bit, then do your “gibbons-ish” flush again. Might try a bit of either solvent, or ester-based synthetic, as both will dissolve...

With all transmission performance issues, I start by making sure the that the fluid is at the proper level and in good condition. I don't know much about those codes, but I would start with a drain...

Water Pump has a weep hole. They're usually good for 150+ thousand miles. It's about time. The belt tensioner is easy. Installing the belt and keeping the cams aligned is hard. Mark the cam...

It has to come out from underneath. Probably easiest to remove the entire bumper cover, search for a how to on that - it's not hard, just awkward.

Remove each 8mm nut holding on the headlight...

Yep. What Hoonk said. Not a difficult repair using genuine parts.

Yes, bad wiring would be a cause. The wiring delivers the electricity, and the firing signal, to the coil. Bad wiring = intermittent spark.

Well, they're right in that you can't mix tires of different model or construction, even if they're the same brand. The system (you have a Haldex, right?) is that sensitive, but if you're getting a...

If the difference in tread depth is 2/32” or less, you’re OK.

There is far more to oil than simple viscosity (it’s like tire size, while ignoring the load and speed ratings, and you should pay attention to the load and speed ratings). You need to follow the...

How close are you to Virginia Beach?

I’ve done three DIM through Xemodex. Not cheap but good work, quick turn around, and lifetime warranty.

The warranty coverage is a question for the dealer that installed the parts.

If you have positive, crankcase, pressure again, it’s time to have the system repaired again. One of the critical parts...

If the engine mounts are original, it’s way past time. Do all 5. Get the kit from FCP Euro or IPD.

The lower torque mount, in particular, doesn’t last long. IPD sells a polyurethane bushing for...

I’ve done it a few dozen times. You’ll need 14 quarts of fluid, new orings for the lines, and some clear PVC tubing.

Search Gibbons Flush on this forum. There will be a few dozen threads.

Or...

That thermistor is in the Climate Control Module. It can be replaced with a used module, then programmed and checked with VIDA.

If the OAT is reading wrong - and you've replaced the outside temp...

I don’t have any ideas on this. Let us know what the dealer finds. Hopefully inexpensive. If you need a CEM, I would go XEMODEX. They’ve done three of mine.

Always get an H rated tire or better. The extra cap ply required to achieve an H rating makes for a better tire under all conditions.

JRL (who is no longer with us) had a lot of experience. He...

The angle gear collar sleeve is very hard to get out. Cut a deep groove in it, use a big pry bar and lots of muscle.

Then throw it away and install a new one with the Volvo Moly grease.

Take a...

Wait, just read the title - is this the rear driveshaft?

It will be stuck unless you drop the center bearing to get a little more room to move it. It appears that you've done that, but make sure...

The drive shaft is stuck in the transmission. That's where the splines mate up. You'll have to use a brass hammer or drift on the inside of the tripod joint, and gently, rather gently, tap it while...

I clean with mineral spirits (which dries, but removes all wax) first. Then, both "Wipe New" and "Cera-Kote" wipes have worked well. I do the car about once a year. They both hold up at least that...

I’ve had Xemodex do two throttle bodies, three DIMs and a couple CEMs. All have worked well. Good company.

Might be cheaper to have a straight pipe welded in there. The resonator (the first muffler) doesn’t make a lot of difference.
