Replacing 98 s70 Turbo

Post by **RobTheModd** » 19 Mar 2011, 11:11

Hey guys, my turbo is on the way out, so insted of buying a new/rebuilt 16t for my car... its a DD so you can see why id rather buy a new turbo then rebuild mine and send it to get balanced..

I picked up a 18t, exhaust, tune, ebc etc...

Does anyone have a link to a walk thru of how to replace a turbo on a 1998 s70 t5?

Probably going to do exhaust and turbo at the same time. Thanks.

I searched on google and VolvoSpeed but I am coming up short. Have you tried searching on MVS?

yeah I tried in the repair database.

I guess now I more so need to know what other parts, gaskets and such, I need to replace.

Have a volvo tech friend helping me possibly next weekend. lol

Remove exh pipe from turbo and tie over and back. Remove all heat shields and the secondary air check valve and set aside.
remove the drain pipe via the two allen screws, it will also be necessary to remove the clamp holding feed and drain pipes together.
Remove air inlet tube and the TC valve hoses from wastegate and compressor outlet.
Remove the water pipes from turbo.
Remove cross-drilled bolts on oil pipe at block and turbo ends and set aside.
Remove the 10 nuts on exhaust manifold. SOAK WITH PB BLASTER!!!! SOAK AGAIN WITH PBB!!!
Once removed you can separate turbo from manifold. Soak those too!

You will need 5 exh gaskets, 8 copper seals for oil and coolant fittings, best to get the two collant rubber hoses now, turbo drain gasket and rubber seal where it inserts into block. Also gasket for secondary check valve if it was removed from its flange.
