98 S70 Tune up nuances and refrigerant refill

Are there any nuances to replacing the spark plugs, wires, rotor and cap on a 1998 S70? Thanks
I hand a friend who has a lot of experience refill my a/c refrigerant, it took two cans of 134a, w/o sealant. Everything went smoothly, the levels held in the mid 40's, nice and cold. A couple of days later when I went into the garage, I noticed a clear liquid that felt oily on the ground underneath the area of the engine where the low a/c port is located. Friend on vacation, can't reach, I still have cold a/c. Any input would be appreciated. Thanks in advance.

No - tune up is straight foward for a Volvo ( lots of torx anf 10mm).

Its possible the water condensation from the AC pipe washed a little oily residue away.If it feels like water with just a hint or glaze of oil thats probably it.

If it feels like straight thin oil then you probably just found whree the last 2 cans leaked out of over time. Make your friend aware of the issue and he will probably drain the system, replace the seal or valve , pull a vacuum and replace the oil and refrigerant.

Pizza and beer is a good start for this type of work but a trip to the tool store where he gets to pick a new tool is probably better. Currently for this type of repair you would be looking at $300-$400 at a AC garage. So pizza, beer and a $40/$50 dollar tool should call it even.
