Summer Progress Update

I have been pretty absent from posting any updates, so let me address that. The semester ended for Steve and I, and I have taken temporary possession of the 850R to finish up the last fixes before selling. I plan on doing the PCV and the clearcoat before the end of June and selling it. We sort of ran out of time with the lack of good weather during March and April which severely limited the progress we could make on the car. Right now we are going to try for around $3000-$4000 for the car, which we think will be fair considering the work put in, and the rarity of the car. Stay tuned as we will have more updates coming soon!

850R - Stage 0 Dreams Pt. 2

While the weather has been on and off here in NC, Steve and I have been plugging away the best we can with the 850R. The most recent work we did was a restoration of the exterior trim, as well as maintenance in the engine day. For the trim restoration we used Chemical Bros. VRP and some old microfibers, and well the results speak for themselves.

This is the passenger side, rear door trim after 1 pass with the VRP. The difference in person is astounding, and after a few more passes (once the sun is back) the trim will really look as good as new.

The upper engine cover / air filter cover also significantly benefited from the VRP. This piece needed a bit of soap and water before we used any chemicals on it. After a few heavy passes it started to regain its color, however the raised grille sections in the middle seem to need a second pass and maybe a wet sand to fully restore their color. It was also from this removal of the cover that we discovered how gross the cabin air filter was!

The engine day with the cover removed, and before detailing.

The nasty cabin air filter, replaced with a new Napa Auto Parts piece.

After replacing the cabin air filter, we detailed the engine bay for good mesaure. We used a shop vac to remove all of the leaves and grime that had built up in all the tiny areas of the engine bay.

The drain hose from the upper engine cover, completely filled with junk!

We are still hoping to get the throttle body mod done soon, so stay tuned!

850R - 960 Throttle Body Upgrade pt. 1

For the 850 Turbo and 850R, one of the many common, cheap mods that enthusiasts will do is redistricting the airflow to the engine. The modification is a 2 part process of using the intake manifold from a naturally aspirated Volvo 850, and the throttle body from a Volvo 960. For this, you need an assortment of parts, most of which can be found at any local pick-n-pull, for ours we sourced all of the parts from LKQ Greensboro. The first step in modifiying the 850s throttle body with parts from the 960 throttle body.

Dirty, but cheap!

So crusty!

As you can see in the images above of the stock 850 throttle body, the plate in the center has a wedge attached. At wide-open-throttle this plate restricts the amount of air entering the engine. The 960 throttle body is the same size as the 850, but does not have these restriction plates installed!

To do this you will probably need a small assortment of torx / hex bits, a screwdriver, and some small wrenches (probably only a 7mm, I used a small set of pliers). I started by removing the sensor on the side of the throttle body on both the 850 and 960, just make sure to keep them separate! The bolts on the 960 sensor were much nicer than the crusty ones from the 850, and these also featured a torx head instead of a 7mm head.

The gross crusty bolts used to hold on the positioning sensor.

There was grime everywhere, but that's junkyard cars for you.

Removing the plates from the center was very easy, I found it works best to unscrew the bolts while the plate is being held at WOT. Once the 2 screws are removed from the center the plate will slide right out. Again the 850 had very cheap screws that bent and warped easily, so I used the screws that held in the 960s plate which were much higher quality.

Installation is just as simple, just hold the throttle body open and slide the new plate in. Mine required a bit on brake cleaner and steel wool to remove the excess grime from the plate and bars inside the body. Once the plate is in I could re-attach the sensor to the side.

Total time for this project was only around 45 and the process was very simple, I would definitely recommend it to anyone looking to gain a small amount of performance for cheap. In part 2 we will be installing the intake manifold from the naturally aspirated 850 into the 850R.

850R - Seat Restoration

Well, more like an attempt at seat salvaging.

To be honest, there is no way to restore alcantara seats that are 20+ years old. That many years have taken a decent toll on the seats on the 850, as you may have seen they have significant matting of the seat material, as well as a significant rip in the lower drivers seat bolster. The only real fix is to have the seats re-upholstered but on our limited budget that is simply not possible. For this restoration project I tried to see what I can do as cheaply as possible with tools I already had. One of my ideas was to use my Conair Fabric Defuzzer, which can be purchased on Amazon for $12. Its mostly used for clothing, but in practice it seems to remove matted pieces of alcantara from the seats.

The section on the left is after being run over by the defuzzer, and the section on the right (the center piece of the seat) is what the rest of the seat looks like.

Left side after, right side before.

While the material will never look new, I am still happy with the results. From a distance the seats look much better, and this process only took me around 20 minutes to cover both front seats with multiple passes. After this I used Griots interior cleaner on the fresh sections, but the affect was minimal.

All of this begs the question "Who the fuck bought a Volvo wagon and decided that suede / alcantara was the best choice of seat material!?" If the car had been garaged all of its life maybe it would have been ok, but this car was being used constantly as a family hauler and daily driver for almost all of its life. By some miracle the rear seats are almost perfect, and god bless the fact that the steering wheel, armrest, and headliner arent made of the stuff.

S60R - Wrap Repair + Driving the Eastern Shore

While the winter is in full swing, it is obviously hard to get any good content out. During my drive down from NJ to NC, I noticed that I had developed a bubble under the 3M wrap on my car. I can only assume that this pocket of air was caused by water melting off my hood, entering a lifted section and then forcing its way further down into the panel.

The gap caused by "popping" the air bubble in the wrap.

To remedy this situation I wanted to take as much care as I could in with preserving the area. First I used a razor blade to "pop" the affected air pocket. Once this was done I trimmed away the damaged pieces that no longer had any adhesive left. Now, because I did not have any new vinyl on hand, I used 3M clear repair tape from Pep Boys to hold the fresh edges down so that no more damage could occour in the area.

Once I received the new wrap piece (only around $5 on Amazon) I removed the 3M tape, and cut a piece around the size that I needed (actually slightly larger to account for shrink). With the headlight off I used a heat gun to make sure that all pieces of the new patch vinyl were adhered to the body with no air underneath at all. I also made sure to cover the back under the headlight to prevent any more lift, this is in part because of the nature of putting a flat piece on a curved surface as it leaves a lifted section unless cut or significantly heated and stretched.

It has now been over a week and it seems like my fix has done a great job standing up to more snow and ice. The process took me about 10-20 minutes, and was a much better alternative than re-wrapping the front bumper! Hopefully soon I can refinish the passenger side headlight to remove the nasty scrapes that it came with when shipped from Germany (came from a D3 R Design).

Stopped at a Royal Farms somewhere on the Eastern Shore. The roads were absolutely horrible, un-plowed and covered in snowdrifts from the wind sweeping across farmland. This weather is what I think damaged my wrap.
