WTD: Bottom oil cooler line - 1998 V70 T5
 

The external oil cooler line that runs from the engine to the radiator is slightly leaking. I am therefore looking for the lower of the two hoses and this is for a 1998 V70 T5, but I believe any pre-ME7 turbo P80 part will do.

Can anyone help?

Thanks

Hi Tweedle,

Is this the part that you mean?

If the ends and the seals at the ends are good, then is it the fat hose that is leaking?

For some of my own ATF lines, which are very similar, I replaced the hose section using appropriate hose and clamps from a local hydraulic company. Cheap and easy. Just carefully cut away the existing pressed clamps.

except I used specialist hose (which was still cheap).

I can provide more info if you need it.

Thanks Steve,
Yes, it is the fat hose joint that is leaking - your suggestion is very interesting. I would be interested in more details of the parts you used previously as I will attempt a repair - nothing to lose really.

Hi Tweedle,

The parts are mostly indicated in the MatthewsVolvoSite.

I contacted a local hydraulics company and explained what I needed.

I think I got a few metres of Multi-Oil hose from this company. Just a few pounds AFAIK.

Find out what the maximum oil pressure might be in your engine. I would think this forum could help you. Maybe look for oil cooler posts.

Tell the local company what you are using the hose for, provide photos or (measure length first and mark the fittings so that you reinstall in the same orientation and then cut the old hoses off) or take the existing fittings in with you if you can, show them the old hose etc, and agree on the desired internal diameter of the new hose. Get appropriate clamps (they will make a recommendation). I used 2 simple crimp clamps per each connection (pence each - I bought a few extra). I staggered the crimps.

I was working with ATF which I believe is fairly low pressure, but I'll leave it to you to find out max engine oil pressure. I think oil pressures are not very high compared with what hydraulic companies are used to dealing with so you shouldn't have a problem.

Once you have done the one that is leaking, I would be tempted to do the other so buy extra hose.

BTW of those two Volvo hoses the out and return are different prices and are available aftermarket.

But DIY is the cheap and satisfying option.

I used a Dremel with a EZ SpeedClic SC456B Metal Cutting Wheel to cut the fittings, it's a really good tool.

Good afternoon Tweedle, I am 100% sure I have what you are looking for in top condition, came of a 96 850R if you are interested I can send you some pics please send me a Pm with your email address

Cheers Vol.

A descent hydraulics company will make these lines up and are more than capable of using the existing fittings:~ If you don't fancy the DIY approach then it is worth asking the question.
I generally use Tom Parker- Preston for local members, they have made quite a few various lines for me over the years (much older cars) and on more than one occasion I've been able to watch the process in the workshop etc.
Good luck.
Bob.
