I don't know what the third on the stud would be, sorry. I just had the two to the stud and green flat connector?

Me too. Green pictured. Sorry, didn't snap any photos of the others.

On my '96 850 GLT with the original factory starter there were the two red battery cables and the wire with the large diameter connector (pictured above) all on the big solenoid stud. The green wire was on the spade below the stud.

Thanks, guys for this thread! Pics make a first time DIY go so much smoother.

Very thorough step by step explanation, Tina! I wouldn't have been able to do it without your help.Several Notes: A new starter (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 starter. 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 starter.
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.

Does anyone know if there are any new starters being sold anywhere that have these studs instead of the flush mounted screws?

Thank you every body for all your help.

A couple of comments - the bolts holding the motor -(14mm) - bottom one is easy to locate but the top - there are three similar
bolts in close order -naturally, I undid the wrong one - its the nearest one that needs attention. I found an ordinary ring spanner the best solution to start them off - then they are only a finger job. Tried taking the round part of the fan out but the bottom
screws were impossibly rusted - even with the slots for ease of removal. I took the whole radiator backing out - then it was a "breeze"........ Again thanks to the avant guard.

Thanks for the tips. I used the same concept on my 2002 V70, 135,000 miles. The car wouldn't start 3 times over the last two days. No noise, no clicks, all the lights lit up but silence. I called the dealer as I had an appointment. He said to tap the solenoid a few times with a wrench or hammer. I hit it a few times and it started up. The next day, it happened twice. Started both times with a few love taps! I figured enough was enough. I bought a remanufactured starter from Napa.

I took out the fan and the bolt for the oil stick. With those out, I had enough room to work. There was a mounting bracket on the left side, facing car at the hood. I took that off the body and the starter came out easily after a few wiggles.

Thanks for your help. My first starter replacement. Not too bad once the fan came out.

Back when I didn't know any better I brought my car to a shop to have the starter replaced. Took them a week. Funny because you can do it in about 3 hours not even knowing what you are doing.

Thanks as this has been a very helpful write-up. I plan on tackling this project on my 99 S70 AWD Turbo in the next few days. Has anyone done this on a Turbo S70? The hose that eventually runs over the motor looks to be one of my biggest obstacles for getting the main starter bolts out. I'm definitely going to try and start with removing as little as possible.

Also, anyone considering buying a junkyard part, check out Amazon. I was able to get a new TYC on there for around $80 with free shipping.

I've done a starter replacement on a NA V70 e/o removing the fan. Don' t know if that can be done on a turbo, but it is definitely possible on a non-turbo car. I said possible, not easy.

Well, luckily I don't have huge hands which is sometimes an awesome advantage when working in tight places. I purchased this car about 3 weeks ago as a project for VERY cheap knowing it'd been sitting almost 2 years and had a very minor run in with a deer.

In a weeks time, I was able to get it on the road and get it to pass inspection and emissions (tricky with the drive cycle) but done. The two major things (other than routine stuff) I knew would have to be addressed were the starter and heater core. Luckily, tomorrow and Tuesday I'm off and it's supposed to be pretty decent weather. I'm gonna knock on wood and hope the car won't need anything else until spring.
