posted by  someone claiming to be A on  Mon Oct 16 08:23 CST 2006 [RELATED]

1. What incriment do you change it and is it easy enough to DIY. What fluid is the best?

2. Are 1998 s70's prewired for the side marker lights that go behind the volvo logo on the front fenders? I wired up my old 940 with them, and I know it isnt hard, but I would just like to know if they are to sve me so touble.

Thanks!!!

    For side marker wire to be in place I believe you had to have an early 850. I put a couple on my 93 and the wires are there on my 94.

    In both cases I could see the factory installed wire sort of behind the upper hinge 'plugged' into a rubber holder - I assume as weather protection.

    So take a peek past the hinges and see if any wiring is back there.

    Jack answered your tranny purge question. Lights: I never found a prewired harness. Made my own and piggy backed onto the parking & signal light wiring. This way the light is on when lights are on and flashes with signals. I used some bullet shaped connectors and squeezed the into an oval which has held for years to the back of the lights. Also used some silicon grease at that connection.

    Regarding Tranny, easy DIY--disconnect top trans cooler line from transmission (best to get a spare clip in case you break it and an o ring). Attach a clear plastic hose and secure with a hose clamp. I run the hose into a 5 gallon translucent plastic water jug marked off in 2qt increments with magic marker. Pull the trans dip stick and insert a trans fluid funnel. Start engine and let 2qts pump out (happens fairly fast). Stop engine, pour in 2 qts of fresh fluid. Repeat until you have gone through 12qts. Reconnect cooler line and you are done.

    I do this every 30K miles and also installed an inline Magnifine filter in the cooler line. I use Mobil 1 ATF--more expensive than regular, but when I changed over to Mobil 1, mileage went up 2mpg which tells you a lot about friction reduction

      Hello all,

      Good reply Jack, just wanted to add one thing. When disconnecting the top cooler line at the radiator, you don't flush the cooler. I prefer to remove the battery tray (a few more minutes, but well worth it) and disconnect the return line at the transmission (the 7/8" nut). If you can get that nut loose (a little PB Blaster and they all come loose easily) and attach your rubber hose there (with a clamp), you then flush the entire transmission AND the cooler in the radiator. You also don't need to worry about breaking the cooler line clip with this method.

      Good Luck,

      Clarification--disconnect top cooler line from radiator, not transmission, my bad...
