All,

Here is my next update.

The air conditioning in my S80 wasn't getting cold enough.

It worked reasonably well at highway speed but not so well sitting at the traffic lights.

I hooked up my gauges to check the pressure and I found the following

AC set to max cooling
Low side pressure - 50 PSI
HIGH side pressure - 100 PSI

I checked my LR2 pressure as a baseline (Same engine and very similar A/C system)
Low side pressure - 40 PSI
High side pressure - 155 PSI

Ambient temperature was about 75 Fahrenheit for both vehicles (tested both within minutes of each other)

Looking at a chart for R134a revealed that my compressor wasn't creating enough pressure.

Unfortunately this means that its time for a new compressor.

I decided to go aftermarket and buy a Valeo unit

I did this because the A/C in my LR2 is still blowing cold and its two years older than the S80 and has similar mileage and it came new with a Valeo unit (Volvo specified a Sanden unit)

I also replace the dryer at the same time (in this case its just a bag of desiccant)
I didn't take any pictures but the desiccant bag is in the condenser and you have to remove the refrigerant and then take out the T-70 Torx plug (The plug is hidden by the radiator cross member so the radiator needs to be supported and the cross-member removed)

Some pictures

Vent gauge showing cooling but not enough (outside temperature was about 75)

At the same time that I replaced the compressor I also replaced the overdrive pulley.
I did this because the old overdrive pulley wasn't allowing the one way clutch action.
It was frozen in both directions.

After putting everything back together I did notice that the belt now moves easily in one direction (engine off) and it doesn't move in the other direction.

For the Overdrive pulley I decided to try Professional Parts Sweden (I will post here if it fails)

With everything installed the AC is now very cold.

The Vent temperature gauge is in the shaded region.

And the low side pressure is about 35 PSI and the high side is about 150 PSI

I may need to add a little more refrigerant when it get hot.

Volvo recommends 800 grams

Land Rover recommends 730 grams

I am only running 640 grams right now

Latest update,

I forgot to include the cost of the overdrive pulley in my last price update so I am adding it in the update below.

I wanted to share what I found when I replaced the overdrive pulley on my LR2.

Comparing the picture for the S80 (Post Above) to the LR2 shows how clean the LR2 is in this area

This is likely due to the use of synthetic oil since new (Mostly Mobil 1 0W-40)

Also because I didn't take a side by side picture of the old part and new part, I am including one here.

One last disclosure, the part that I bought is an Overdrive Pulley not a Overdrive Decoupler Pulley.

The difference is that the Decoupler has a spring to dampen the belt movement.

Because the belt tensioner also has a a damper I decide to get the simpler part and see if it lasts longer than the original part.

Note: the part that I bought is also significantly cheaper.

One more update, I don't get to drive the S80 very often but I did drive it once last week and it is running extremely well. The shifting is smooth and the engine is strong. I like driving it even more now as compared to when I purchased it.

Thanks

Paul

It’s been a year since I bought the S80

And I did have to do the maintenance (as documented here on MVS) that was neglected by the previous owner

Now that I am current on typical maintenance and repairs the car runs amazingly well

I could not be happier with my purchase

2010 S80 purchased on 11/5/2018 with 123,636 miles

As the picture shows I am at 135,012

And I haven’t done anything for months (ok maybe lexol on the leather)

Volvo did an amazing job with the P3 and the 3.2

And MVS is such an amazing site with so much great information that my S80 drives like a new car.

I remember reading a post from Matthew1 (the M in MVS) about the cost of used cars and the impact on hard working people. Hopefully this thread inspired someone to buy a P3. Because as I’ve shown the P3 isn’t that expensive if you can do some repairs yourself. And the P3 Volvo is a very safe car.

Take care

Paul

Well done Paul

You are driving a $60,000 luxury car on a $8000 cost, and you could probably get most all of it back if you chose,

Abscate,

I completely agree its an amazing car for the $$$$.

If I ever sell it I would buy another P3 (3.2 or 3.0T)

Volvo did an amazing job engineering this Vehicle.

I swapped cars with my Son today, so I got to drive the S80 and he is driving my Audi 2.0T.

The power delivery is so nice on the S80

I do prefer the inline 6 cylinder.

Everything works in the S80
- Heated seats front and rear
- Rain sensing wipers (the sensitivity is easily set using the thumb wheel)
- BLIS
- etc.

The ride is so nice in this car.

The seats are extremely comfortable.

I am really glad that I got it.


If I ever drive the S80 to my mom's house (in Loudonville) i'll let you know, but its unlikely because I live about 3000 miles to the west.

Take care and stay warm

All,

It's been 6 months since my last oil change.

I decided to use a different oil, I was using Mobil 1 0W40 and I did have to add a quart during the 6 months of usage.

I decided to try Motul X-clean 5W40 (and a new filter)

And because I was going to be under the car I decided to replace 4 quarts of ATF fluid as well.


Here is the oil

And here is the transmission fluid

I prefer to use the AISIN fluid because AISIN is the manufacturer of the transmission
