Fill the engine oil.
Run the engine to operating temp.
Check for oil leaks from the sump or the oil cooler.
Install the splash sheild under the engine.
Check the oil level.Top it off if needed.

Some more notes:
You may have to support the Right side of the engine and drop the subframe a little to get the pan out.

Have someone help you when installing the pan and watch the o-rings to make sure they do not fall while installing the pan.

Make sure when the pan is off you remove the pipe in the oil pan and replace those o-rings at the same time when you have it apart.

Also make sure you remove the oil pick up tube and replace that o-ring.

I think that is about all.
If there is anymore quiestions feel free to ask.

Sorry I don't have the part# for the o-ring kit but the dealer sells it as a kit.

RE: Oil pan o-ring replacement instructions!!
 

one note I would strongly rec. staying away from razor blades ,scrapers and any sharp objects when cleaning the pan and engine block surface no grinding !!!. These surfaces are zero clearance any damage and they will not seal properly. when installing the chemical gasket becareful not to use to much, a light film as i said it is a zero clearance fit! thanks

FYI there is a special disc that can be purchased that can be used to grind the old liquid gasket off.
It is a special disc for cleaning aluminum.

Tech - thanks for posting the instructions on replacing the oil pan o-rings.

I recently took my S70 to a dealership to diagnose a loud ticking noise that comes and goes. Its especially noticable at stop lights.
The lead tech told me that the oil pan o-rings had to be replaced and that it was the cause of the ticking lifter noice.

Is this possible? Or is he miss diagnosing the problem?

RE: Oil pan o-ring replacement instructions!!
 

may have missed it, but didnt see in your instructions to replace the pickup tube o-ring.. that is a vital

RE: Oil pan o-ring replacement instructions!!
 

I did say to make sure to replace it above.
Didn't make instructions on it because it is only 2 screws to get the pipe out.
If you went through the entire rest of the process and couldn't figure out how to get the pipe out then one shouldn't attampt the job.
Nothing against you just a comment.

Johnny I would say the o-rings are bad as well.

RE: Oil pan o-ring replacement instructions!!
 

ok thanks for the info

I am having a small garage doing this job for me, however, I am going to provide all the parts that needs replacing, could someone possibly give me a list of things?

RE: Oil pan o-ring replacement instructions!!
 

ok so just to have more info

I need a new oil pan o ring, new engine oil, oil fliter, what else?

Thanks

RE: Oil pan o-ring replacement instructions!!
 

You will need the oil pan o-ring kit.
Sealer that is very expensive.
Pick up tube kit if you don't buy the kit.

Any chace those pics still exist somewhere? Looks like this will be my weekend project. Also, it appears that all the autoparts stores have a bent against Volvo...none carry any reapair manuals. Since I'll have to order one, which would you recommend? I usually just pick up a Haynes.

Thanks.

1998 S70 GLT

I will have to dig them up not sure why they are not working.

Bump. Still waiting for the pics if you have them.

Sorry this is the best I can come up with right now. I had them saved on my PC and it crashed.

Im knee deep in this right now!But...
 

It sure isnt as easy as the instructions!
I have a 98 V70 I am doing this too- cant the pan loose but cant get it down!!
I have PS lines in the way- I undid all the clamps but I still cant get it out!
Its like the pan needs to come straght down- Im hitting lines on one side and fram rail on the other!
What am I missing???

You also have to work it around the pick up tube.

Got it out- had to bend the tab out of way. Going to be interesting putting it back up!
This poor car- what a mess inside. The center of the pickup tube was pretty much plugged- I sure hope it cures my lifter noises! I had a tom of oil coming up into head just maybe not enuff pressure.
Well let everyone know if it lives or not...

Ok well that didnt work...
 

FInished it up today- thought I fixed it bu realized the noise from the long bolt hitting the flywheel was covering up noise. OOOPS! the rear center bolt on pan wasnt right- must have put the wrong one in. I took that out and that quieted down- do I need that bolt? theres like 30 others!

Anyway- my lifters are a little quieter but still way to loud. I suspect they may be clogged judging by what the pan looked like.

SO whats the next step? New lifters?

Which bolt exactly? One the flywheel? If so then it was not in there right.

Did you drive it afterwords? Sometimes you need to drive it for a little while to make sure all the lifters are pumped back up.

It was one of the long oil pan bolts at trans side of oil pan in the center. There are like 4 long ones back there.

I ran it for a while varied the speed but cant drive it until i get tires- I have cords showing. Its a project car- but I want to get the engine stuff done before I venture off in to suspension land.

Does it hurt to run these with noisy lifters?

Not really as long as you have alot of oil flowing under the oil cap.

For the bolt try to put it in again. It might not have been straight.
