See what our forum members have to say about replacing your volvo starter motor
The volvo starter motor is an electric motor powered by the battery, commanded on when the driver rotates the key to start the engine. The modern Volvo starter motor is a permanent magnet direct current electric motor with a solenoid mounted on it. When current from the vehicle battery is applied to the solenoid, the solenoid engages a lever that pushes out the drive pinion on the starter driveshaft and meshes the pinion with the starter ring gear on the flywheel of the engine.
The solenoid closes the high-current contacts for the starter motor. The starter motor then turns the engine. Once the engine starts, a spring in the solenoid assembly pulls the pinion gear away from the ring gear, and the starter motor stops.

Repacing the volvo starter motor – I just accomplished this job, here’s how I did it. Please forgive my lack of knowledge of the correct names for many parts, I am a complete amateur and I stumbled my way through with the help of forum members!
For the purposes of this description, left and right will be relative to the person standing in front of the car facing the engine. Also “in front” will then refer to closer to the person.
Symptoms: Key is turned, click is heard but no attempt to turn over. Headlights bright. Jump starting does not coax even an attempt at turn over. ie. not alternator or dead battery, not fuel delivery as it would try to crank then. This car is a manual transmission so no PNP to worry about.
Tools: socket driver and extension, 14mm and 12mm sockets, torx drivers and a few other assorted sizes I did not measure. 2 nylon zip ties to replace the ones you cut. A large flat head screwdriver for prying stubborn connectors.

Very thorough job and an excellent writeup!
I had forgotten about the side bolts on the volvo starter motor, but now I remember those were very hard to get to without removing the fan.
FYI, #5 is an electrical valve that is part of the Evap system that routes vapors from the fuel tank first into a carbon canister and then into the engine.

Very thorough step by step explanation, Tina! I wouldn’t have been able to do it without your help.Several Notes: A new volvo starter motor (Bosch) from the dealer doesnt have the studs for mounting the bracket. Instead, there are 2 flush mounted screws which look smaller in diameter than the studs. The mechanics just leave the bracket off when replacing the volvo starter motor. One can buy the solenoid seperately, which is what failed on mine. $271 for the solenoid so you can use your original motor, or $309 for a whole new volvo starter motor.
When pulling the fan shroud shelf, take note of how the vacuum lines are attached to the solenoid underneath. Yellow plastic line to the vertical fitting and lavender line to the horizontal fitting. Yellow line terminates on the vacuum fitting on the throttle cable spool bracket, the lavender on the SAS valve a top the turbo.
