1998 S70 T5 - Name That Hose

Post by **ddpphx** » 15 Feb 2009, 18:27

Wow - I couldn't find that diagram in VADIS, MIJ. Thanks.

I think I will go ahead and add 30713305 to my order - $5 won't hurt. Very hard to get a read on the size of that tube from FCP's pic.

Thanks to all.

Per VADIS, there seem to be two different varients on that hose.

31104675 fit engine numbers -2348305 & 2816210-3411287
30713305 fit engine numbers 3411288-

Your engine serial number should be on the front of the timing cover and fairly easy to see.

That turbo coolant hose is 30713305. I was trying to buy that hose from the dealer last week. Apparently its been a very popular/common item for them (and they sold the last one right before I got there).

FYI, the hose carrying coolant into the turbo (6842190?) is subject to damage from the O2 sensor.

This repair is for 1994 850 Turbo Wagon, I was told that these hoses do go bad often, so perhaps this will help someone else trolling for a fix.

Hello all,

The new 30713305 hose came in today from FCP, and I pulled the old hose off. The old hose has an impression that reads 684275.

The hoses (see pic) are a good match as far as size goes - but the new 30713305 is a multi-ply, with a white material on the inside. The old 684275 is just a plain rubber hose.

Will install 30713305 (barring objections) and let you know the outcome.

If it fits on the lines it looks like they learned from their mistakes and beefed up the hose.

Just installed the new hose -- fits marvelously.

Thanks to everyone for guidance on this one.

Glad it fit! Now I know if mine goes.
