Volvo Coupes/Sedans/Wagons 1970-1989 Repair Guide




Manual Seats
1800 SERIES, 140 AND 160 SERIES

The front seats are retained to the car by bolts (usually four) into the floor rails. In most cases these are easily seen and removed, allowing the seat and its tracks to be removed from the car. On 140 and 160 series, it may be easier to remove the bottom cushion (push down, release the clips and lift the cushion off) and then remove the seat frame from the tracks. During removal of the seat be alert for any wiring running to or under the seat which may become fouled or damaged.

If the seat itself is to be worked on out of the car, it is very helpful the support it on crates or sawhorses; the design of the seat makes it awkward to manipulate and top-heavy if set upright on the ground. Seat removal is also a good time to perform a thorough cleaning inside the car as a large open area is created. The amount of loose change found under the seats usually makes this project worthwhile.

When reinstalling the seat, note that the elevation and rake (tilt) of the seat may be adjusted by selecting alternate bolt holes. Once the seat has been examined and the mounting system is understood, a little experimentation can yield a most comfortable seating position.

200 AND 700 SERIES

See Figures 1, 2, 3 and 4

The front seat and its rails may be unbolted from the floor of the car. Many cars have heated seats; it will be necessary to disconnect the wiring harness for this system before removing the seat.

On the early 760 series, it is necessary to remove the seat belt anchor from the side of the seat. Remove the screw in the rear of the side pocket, lift the pocket out of the way and remove the seat belt bolt.

After all the retaining bolts are removed, the front seats in the 700 series are removed by sliding the seat to the rear of its track and lifting upwards to free the seat from the catches.

The rear seat cushion is removed by pressing down directly over the retaining clips (freeing the hook from the loop) and lifting the cushion clear. The rear seat backrest is held by catches which hold the upper bar in place. These catches can be released with a prytool; don't bend them anymore than needed or reassembly will be very difficult.

When reassembling the rear seat, always install the backrest first. Make sure that every clip engages properly and is firmly closed.

Do not disconnect any wiring for other components. Many other units may be found under the seat-leave them connected at all times.

  1. Remove the rear mounting bolts and lift the seat clear of the car. It will be heavy-an assistant inside the car can ease removal.
  3. Either support the seat on crates or a clean workbench or place the seat on a clean blanket to protect it.
