1998 V70 AWD Front Oxygen Sensor Swap w Photos

1998 V70 AWD Front Oxygen Sensor Swap tools

MVS Forums contributor deepsouth shows us how a front O2 sensor swap is done on an AWD Volvo P80, including photos. This is a “from the top” DIY, meaning it’s how to do the front sensor swap access from the engine bay, not under the car. Outstanding.

Just swapped the front O2 sensor on my 1998 Volvo V70 AWD and documented it for those interested. On the AWD the sensor must be swapped from the top and it’s a bit of a bear to reach. Here are the steps.

1. Disconnect negative cable from battery.
2. Remove MAF sensor connection, smog pump hose, and upper hose clamp from turbo air pipe (see photos).
3. Remove air box from engine compartment.
4. Disconnect vacuum lines from upper half of turbo air pipe (2 lines, one on side and underneath) and from lower pipe at PTC Nipple (3 vacuum lines and an electrical connector…see photos).
5. Remove hose clamp that holds turbo air pipe to turbo. This is largely a “by feel” clamp and is difficult to see (see photo).
6. Remove turbo air pipe.
7. The upper and lower O2 sensor connectors are now visible. The red tab is a locking mechanism and must be slid out before connector can be removed.
8. Using crow’s foot O2 wrench (for rent at any parts store), u-joint, and long extension (or many small ones pieced together :) ) break loose old O2 sensor. This step is not fun nor easy and there is very little clearance.
9. The new sensor is a PITA to thread and install as well. I wound the wire the opposite direction several times before attempting to thread.
10. Tighten new sensor with crow’s foot and reassemble. It’s also a good time to clean and inspect PTC nipple.

Volvo 850 DIY Inner, Outer Tie Rod End Replacement w/pics

Volvo 850 DIY Inner, Outer Tie Rod End Replacement

MVS Contributor Jason Reed slays the tie rod dragon with one swing of the DIY sword.

This DIY guide shows how I replaced the TRW inner and outer tie rods on a 1997 Volvo 855 GLT with 165k miles. I benefited greatly from the write up by Nlemerise who did the job on his V70. His guide was posted on Swedespeed.

The link to his PDF appears dead, but luckily it’s also in the MVS database here.

Ozark Lee has also written up a procedure for the outer tie rod ends here

I took pictures at each step of the procedure, so it was easier to put them into a PDF than upload each one of them one-by-one.

S70 DIY Boost Gauge Install Complete Guide

S70 DIY Boost Gauge Install Complete Guide

MVS Volvo Forums Contributor mecheng crushes the ball out of the park with a guide on installing a boost gauge in an S70. This will be identical to V70 and XC70 Volvos, 1998-2000 model years, and very close to 850s. Here’s my 850 headliner boost gauge install.

Remember, it’s always the pink wire.

Ok, I realize this is not rocket science but there are some tricks and advice I can share and I haven’t found a complete guide to step people through this. It is not hard, but takes a bit of patience to do the job cleanly and safely as you are taping into electrical wires and adding new vacuum line.

If you are like me, you want to know how your engine is performing and boost / vacuum is a key parameter that can help diagnose leaks, boost fade, not reaching peak boost, etc.

Volvo XC 60 Rear Brakes (Electronic Park Brake) Replacement

Volvo XC 60 Rear Brakes (Electronic Park Brake)  Replacement

MVS Forums member Tiny Tim 077 drops a nice DIY: Volvo XC 60 Rear Brakes (Electronic Park Brake) Replacement DIY, with photos.

Below I have put the instructions for replacing the rear linings with Electronic Park Brake. When I discovered that my rear linings needed replacing I got the parts and figured as I always do when replacing my own brakes it would be a hour job and not have to pay someone for something I can do.

This is a downloadable PDF. Click below to get it.

Very soon into the job I realised that the Electronic Park Brake (EPB) was going to be an issue. After research on the forums I soon realised that you needed a computer to retract the EBP motors to push back the pistons to get the new pads in. After an hour of searching one post referred to the instructions in the actual of the box of the new pads. I looked and true as nuts there were the instructions from Volvo without having to use a computer to retract the rotors.
