I replaced the distributor cap and rotor on my B280F (267,000+ miles) this morning and wanted to give a heads up to those who may be planning on doing it.

You will need - 8 mm wrench (open end and "shorty" socket recommended)
*2.5mm Hex Key
Angle Mirror - useful for viewing bolts.

You will need a 8 mm wrench to remove the distibutor cap shield and the distributor cap - a "shorty" socket wrench will come in handy reaching in between the engine fan blades to remove the distibutor cap. An open end wrench 8 mm (small as possible) is recommended also. There are 3 8mm bolts that hold the distributor cap and its shield in place. The shield over the cap is actually two piece - the top section section snapping off after depressing tabs. The main section is held in place with the 3 bolts that pass through the shield and also hold the distributor cap in place.

*2.5mm Hex Key was needed to remove the Rotor. There were three Hex bolts? holding the rotor in place - !However! the GP Sorensen replacement Rotor I had did not have same type of bolts - the heads on the bolts in the replacement GP Sorensen rotor appeared that they would take a Phillips head - however I didn't confirm this. The Rotor I pulled off appeared to be a Bosch so I assume it is OEM. I swapped the Hex Key type bolts out of the older rotor and placed them in the GP Sorensen replacement I bought.

Forgive me a guys first time I have ever replaced this on a B280F - this is my first V6 (Volvo or otherwise) so I am a bit excited. I figured this info would come in handy for a novice.

Advance (chain auto parts store) had the cap and rotor in stock though a bit pricey - over $50 for the cap and $20 for the rotor.
