oil line question

OK, I am lazy I admit it.
I brought the 94 940 turbo into the garage for an oil change and looked
under it.

Looks like a typical car, however right at the oil filter mounting plate
there are oil lines that go to (I guess) either a oil cooler or the turbo
(or both?)

looking on the us passanger side toward the front of the car some one put a
simple rubber hose on the oil filter plate boss where I suppose a barb
nipple holds it on with a hose clamp.

This cheap set up filled me with considerable fear of long trips where the
oil gets real hot swells the hose and ...god I dont even want to think of
what might happen.

Is a hose of SUITABLE quality whats suposta be there, or is there some steel
pipe ting, or what?

Thanks

--Steve

Those hoses carry coolant not oil. If you're worried about them, buy
new ones, and new clamps too.

Coolant? Isn't he talking about the oil cooler lines that connect to the
oil filter mount? The turbo water lines only connect to the turbo and
they go to the radiator hoses.

It's caled an oil cooler, but it's really a cooler/warmer. It brings the
oil up to temperature quicker in cold weather and helps cool it down in
hot weather. If you're noy careful when changing the oil you can cock it
so it will chafe a hole and puke all the coolant.

If they've been altered from original setup you could replace them with
new hoses, if you just don't like the original setup (rubber hoses with
crimped metal fittings on the end) you could get some braided stainless
covered lines from a race shop.

Originally with Volvo turbos (your car for example) there were hoses
that carried oil from a thermostatic device at the base of the oil
filter to an air cooled heat exchanger. With the intercooler and
radiator redesign in the early '90s, the thing at the base of the filter
became a liquid to liquid heat exchanger that has coolant in the hoses.
With the 850, they sent the oil (so oil in hoses again) to a liquid to
liquid heat exchanger in one of the rad tanks similar to the
transmission cooler. Then in 1999 this heat exchanger was mounted on
the side of the engine (so no oil hoses again), which is where it has
been on every turbo since, as far as I know.

As Bob mentions in another post, these liquid to liquid heat exchangers
also heat up the oil when it's cooler than the coolant temperature,
aiding warmup.
