03 xc90 with 83k miles.

Its got the "no oil pressure stop engine safely" light coming on when it gets up to running temps.

I am having my mechanic drop the pan, clean for sludge and replace all the seals and O-rings.

Does anyone remember which O-rings need to be replaced. I read somewhere there are 5, I bought the set along with the volvo sealant but need to give exact instruction to my mechanic on which seals to replace (he is not a volvo guy) and I dont remember which ones.

thanks

 

There are two between the pan and the bottom of the block. The oil pickup tube should be removed, cleaned and the o-ring on the end replaced. There are two seals for the oil cooler. The dipstick tube o-ring should be replaced. And I believe there is a transfer tube in the pan that can be unbolted and removed to replace the seals.

 

thanks, where is the oil pickup tube, I checked the seals for the oil cooler - they dont look like sizes that cam in the kit.

thanks

 

Yeah, for some reason the oil cooler seals don't come in the kit. Honestly, the old one can probably be reused, but I always replace them when I do a pan.

The pickup tube is on the bottom of the engine, held in with two bolts. Very easy to see once the pan is off.

 

I saw a write up somewhere that stated 5 seals need to be replaced when dropping the pan:

2 for the tube in the pan 1 for the pick up in the block and 2 from the block to the pan on the passgr side

It may have been for an s80 T6 engine but I thought they were the same - does this not apply to the xc90 ? I didnt see 2 from the passgr side to the pan but the pan is not off yet.

Thanks.

 

Those are all mentioned in my post, plus the oil cooler and dipstick tube.

 

ok so there are 2 on the passgr side from the block to the pan ?

thanks for your help

 

Correct.
