Soon I'm going to toss new plugs, rotor & cap in my 98 S70 GLT. On past cars I've had, the rotor just slipped on a shaft, end of installation.

According to my maintenance manual, on this volvo there are 3 screws that hold the rotor on, and it mentions making a mark so when you put the new rotor on, you can align it to the same position the old one was at. How critical is this?

Also, taking the cap off looks to be a pain with everything else around it, especially reaching the bottom screw that holds it on. Any tips on getting it off?

And regarding the flame trap, my manual implies that only the non-turbos have a flame trap, is that the case? If so, does the turbo have anything similar or a PVC valve I have to check/replace?


Thanks

What you are planning on doing is relat easy. I just did Plugs, Distributor, Rotor, Coil Wire, Plug Wires, & Cabin Air Filter. The whole job took 2 hrs max.

The Distributor/Rotor is relat easy. Remove the top of the air filter box. The Distrib is held on by three 8mm screws. Two are easy to get. The third on the bottom takes a bit of trouble but can be gotten at with a 1/4 socket and extension w/swivel.

The Rotor comes off with a very small allen wrench - once again metric 3 or 4 mm I believe. The Rotor and Dist are notched to ensure correct install alignment.

Best of Luck

Replacing those distributor parts is easiest if you first remove the lower half of the air cleaner box, it just unsnaps. You'll need a 3mm torx bit to unscrew the rotor and there's no need to mark it as it only goes on one way, can't botch it.
