Turbo hose about to go south

[tailor]

I was under the car this afternoon , because I wanted to do a drain and fill using Mobil one ATF.Well what a surprise at the colour of the ATF, it was really dark, I drained only 2 litres, because I forget to get another two bottles and It was Thanksgiving today, nothing was open ( I know I should have waited and a little mess ensued.
To the point here is a pic of the turbo hose without a clamp and also looking as if it is going to burst really soon .I suppose it is good to get under the car once in a while.

Is it this pipe here from FCP

Any help /confirmation would be welcome.

Paraphrasing Arnold Schwarzenegger - I think it has a "Tuma". That would be real high on my list of things to replace.

So, Ozark have I got the right hose?

[Ozark Lee]

It looks right from your picture but VADIS doesn't bring it up and the eEuroparts and FCP diagrams don't show it. That line is a coolant line, not an oil line though. I haven't had to mess with my turbo yet so I must plead ignorance.

I agree it's not a turbo line...do you have an AWD? It looks very different from mine, including location.

Edit: I stand corrected. I do have that on mine too...just looks slightly different but it's called a "coolant inlet" line for coolant and not oil (antifreeze). Here is a diagram. It's #9:

I had the same situation a few months ago. That hose had turned into the consistency of jello.

I took the old hose to the big car parts store in town, gave it to the kid at the counter and said "find me something as close to this as possible". Important that the diameter was close and it had a bend in it...I didn't care about length because it could be trimmed.

He came back with something that was almost perfect...I should have asked him which application it was for because I knew this question would come up. I had to double clamp the side that goes on the smaller diameter inlet, but other than that it's been on the car since then with no problems.

It was only $5.

Maybe you can try the same routine with your local parts store.

Thank you gentleman for your input, a new hose is on order.

For those of you that want to pick one up from the Dealer.....
here in Canada $9.95 plus two clamps @ 2.95 each, screw type not the Oetiker clamp, no doubt still cheaper in the US and even more so at FCP but factor in shipping and time, not too bad overall.
Part numbers:
Hose is 6842190 as stated on the FCP site see here:

Clamps are 988023

Will report back on the fitting!

1994 850 Turbo coolant hose replacement

The Turbo coolant hose is not really that difficult to replace. A little more fore thought might have saved me time and from uttering more than a handful of the most colourful words that I could muster. The lack of height from my ramps made working on my back rather unpleasant as I had to forgo my "dolly" ...and then there was the "wetness", doey fingers and forearms none of which seemed to go between any gaps.
One of the other problems facing me was the hose clamp nuts were facing away from me which made the access awkward. I had initially thought the top clamp had fallen off, in fact it was covered in oil and other gunk.


A lot of time was spent trying to gain access to these nuts. It was only after some time that I realized the way forward was to tackle the rubber hose replacement in the method outlined below.

The Turbo coolant hose, seen in the diagram below and the pic, according to Volvo techs is a regular replacement issue. I suppose the heat of the turbo accelerates the deterioration of the said hose. My hose had a "aneurism" and was going to rupture at some point.



I am going to assume the car will already be on ramps or jack stands, if you have a lift, bless you! Please exercise caution, block wheels and ensure you have protective eye wear, coolant and other detritus always has a habit of falling on me, you might have a similar experience.

Remove and save the coolant for re-use,( if it's still good) by opening the stopcock under the radiator, see here as to how: Post: https://www.matthewsvolvosite.com/tstat.php
Excellent instructions as how to drain coolant.

It may be possible to "get away" without having to drain the coolant, I would welcome some other ideas. As the coolant was washing down on me, the thought of the little Dutch boy with his finger in the Dyke did come to mind. I tried in vain to plug the hole after the pipe removal (block side) before being soaked, but as usual no extra hands to be found. I could not stem the flow of colourful language either. The coolant pretty much drained all over me and the garage floor.....drain the coolant first!
The removal of the heat shield, seen in the 3 pictures below, which covers the turbo gave me access to the metal pipe to which the hose was attached :






It is only necessary to remove 3 bolts from the heat shield and loosen a 4th on the fire wall side of "L" bracket so the "L" bracket can be swung out of the way.
It does require more than a little manipulation to get the shield out, lifting the shield( at the firewall side) up towards you and sliding the (block side) down and away from the metal pipes should give you success. For my part I put a little antisieze on the bolts before re-installation.
Now would be a good time to get a little shine on the heat shield if you wanted to.

Once the large nut on the metal pipe(see diagram below) was loosened it allowed me to remove the metal pipe with the rubber hose still attached, I then removed the two still joined pieces out over the top of the engine.
Be aware that there are two small copper washers on the metal part of the pipe, that if lost, will surely lead to leakage, they probably should have been replaced.


The new hose was attached and loosely tightened to the metal pipe. I made sure that the nuts on the clamps would face me, towards the under side of the car, passenger side, were I would be laying. The final adjustment would be made from beneath the car after attaching the top metal pipe to the turbo, this is because the elbow on the hose needs to be respected.
The upper and lower clamp nuts were now facing me and with multiple extensions on a ratchet I was able to tighten it all up. Once the angle looked correct I proceeded to tighten the large nut on the turbo from the top of the engine. There is a little lateral movement on the metal pipe, make sure that you do not put any strain on the rubber hose.

Refill with coolant and check for leaks.

This may come in very useful sooner than later.

Thanks.
