Oil cooler pipes

[Wezzel]

Whilst having a poke about under the car yesterday (as you do) I noticed some very corroded pipework. It looks like the oil cooler supply and return pipes. They run along either side of the sump (metal pipe) then there is a short rubber section (presumably to absorb the engine vibration) and finally metal again where the dissapear under the radiator. It's the last section which is almost rusted through.

Is this a common fault on a W202 and does anybody know if it is a costly repair?

Thanks in advance.

Cooler pipes are fairly cheap from the stealer, i paid about £25 for mine...for my W201.
Easy to change too!

Thanks Zakh,

Do I need to drain the oil or can I simply clamp the rubber pipes and then top up later?

 

[zakh]

No need to drain...just unbolt and put the new ones on!

I seem to have got my wires (or pipes crossed). It wasn't the oil cooler which was the problem but the transmission oil cooler.

The car has never had a transmission oil change so I booked it in today with an indy for new pipes, gearbox oil and filter. Mercedes says "sealed for life" the indy says "every 60K miles". I think I know who to believe!

Definately change the ATF at least every 60K or sooner if all town mileage.

Changed mine yesterday and all the signs are good although it's surprising how dark the old stuff is. This is the second change by me so I know exactly how old the fluid is (48K).
Also fitted rear pads, changed brake fluid and antifreeze.

Shifts are now really smooth.
