Cover hole should seal over flat spot on head.

I made this a couple weeks ago to read the ECC codes from the OBD II port on my '96 Turbo Wagon. It is documented in my ongoing thread (at this point) to determine my intermittent ECC failure, but I thought it could be mentioned in the tool section. I was going to do a simple momentary switch, LED a...

"target market" is really the key here, not the technical concerns. * Although I wouldn't consider head skills necessary, you will need to understand your car more and more as time goes on starting right about now. It's already 14. Almost time for its own learners' permit. I'm not trying t...

Common source of a fuel smell under the hood is one or more failed fuel injector o-rings. While not a full rebuild, this covers most of the ground for a 1998 Volvo S70 GLT. The ideal time to do this is when you will have the intake manifold off (e.g. PCV system service) so you can remove any pintle ...

SHORT VERSION Here are the most common bulbs you’ll need to replace besides headlights and the number they’re sold under (Osram, Sylvania, Eiko, etc.).

<<< Edit by Matthew — be careful with steel bolts in the aluminum block! Double check the torque values (ask here!) They may be aggressive... if you know, please chime in here. Use a 1/4 inch torque wrench for this work with the block, no bigger! >>> Hey all-- I know it's been written before, but I...

Hopefully, the photo below will help make things a bit more clear (in addition to the youtube video posted previously). - The mechanical tensioner has an eccentric design , i.e., as the adjusting tab "A" is moved, the axis of pulley rotation is changed to adjust the tension on the TB. - Th...

Hey all-- Finally got fed up with the host of evap codes on my 1998 V70 AWD and went ahead and replaced the canister hoses, rollover valve hoses, purge valve (and surrounding hoses), and the three inches of rubber line connecting the small vent filler tube to the hard plastic line coming from top of...
