2.5 Diesel - Oil Cooler Pipes

Hi,

As u all know, I'm not mechanical in anyway.....so i'm am using a local (to work) garage to do my oil cooler pipes on Wednesday...

Reason for the post is....I have pipes and oil filter, guessing its a good time for oil change as there is not much in there and probably gonna lose the rest in the process! I know that there is a chance of the rad giving up on the threads, but any tips i can give him? or guides? Really don't wanna shell out for a new rad....

Just a check - 9L of 5W-40 Oil?

Thanks Guys!!

Give the fittings a good spray of penetrating oil tommorow morning, evening and again on Wednesday morning. I use 10w40 semi but when I had my Omega (same engine) years ago the recommended oil was 5w40 synthetic.

Cheers Davie!

As Davie F says you really need to drown it with penetrating oil, but to be honest the chances of getting the pipes off without stripping the threads is pretty remote and i do wish whoevers doing it the best of luck but be aware you might need a new cooler.

Right, will do that. Hopefully fingers crossed all ok......something has gotta go right with this car!!

Try getting a bit of heat on the nuts but not to much that it melts the rad.

Make sure on replacement they are lubricated with copperslip and not overtighten,d then next time it's removed it should be easy

As well as copperslip on the threads, wrap the joints on the outside with denso tape.
It will prevent future corrosion.

It's electrolytic reaction between the aluminium threaded stub on the cooler and the steel nut on the hose that's the culprit !!!

On way to garage, guy put some stuff on it yesterday, told him what u guys said so fingers crossed!!

If I get away with no rad I'll get him to do front shocks and steering damper while he's there! Parts are in boot for last 2 months!!

Oh.......walking home......

Didn't go well (as expected) got Oil Rad Ordered, hopefully will go good tomorrow!!

The mechanic is wondering if/hone the oil rad comes out by leaving the air con rad in situ?!

Any suggestions gratefully welcome. Would like to go away at the weekend.....

Unfortunately its near impossible to remove cooler pipes without destroying cooler but atleast you've give it a go, nothing to loose and all that.Anyway a/c rad can stay in but obviously intercooler has to be removed to replace oil cooler and dont forget to tell him to put copperslip on joints when renewing, not too difficult a job really. Good Luck

DM,

I'm not mechanical whatsoever, but the oil cooler brackets seem to sit under the ac rad bolted from underneath.

Once unbolted is it just a case of a wiggle/twist to get the oil rad out? Or is there a better technique??

Cheers.

I dont know what stage your at, as in ,he's justed tried to remove pipes. But starting from beginning,remove top slam panel,remove intercooler and associated pipes,unbolt oil cooler and remove side panel,then undo top pipe and then lift cooler up abit to remove bottom pipe and it should just slid out. Or if you have a copy of Rave get him to read that and it should be pretty self explanatory for a mechanic.

Have to travel that road myself soon... Do we think there's any merit in heating the oil cooler pipe nuts before trying to undo? I have a micro-blowtorch attachment for my gas soldering iron that is quite good at delivering concentrated spot-heat... Anyone had any success with a similar scheme?

You'll be lucky, I don't think, even cutting the nuts lengthways would not free them on mine, the corrosion was too advanced.
If the actual pipes are not corroded it's possible to cut off the rubber sections and get new ones crimped on.

dm your right done mine twd weeks ago, the mans spot on.:beer2::beer2::beer2:

Right,

It's back together.....unfortunately not done....

The rad we ordered didn't come in as we suspected it may not.

Good thing is we didn't try the nuts to much so didn't break anything!! So no dramas....

So need to find a supplier that actually has one in stock, then try again next week!

Oil Cooler in......

Trying again next Thursday..!

Update - that job all sorted!
