Arrow W123 Oil cooler hose blew!

At least my 300D was in the driveway idling! My replacement is a Conti, Made in Germany, but either my current hoses are really stiff and hard or this one just seems really soft. Has anyone used these before and are you satisfied with them?

My car was idling in the driveway when I noticed oil dribbling out from under the drivers side right in fron of the wheel! Oh, crap! Well, it could have been worse, I could have been going down the freeway! Thing is, my hose didn't look bad but it just started leaking.

I guess looks aren't everything!

Welcome to the club. Seriously, we should start a fraternity of drivers that were lucky enough to survive this ordeal.

At least you weren't on the highway like me. I caught it very quickly, but you can see the mess.

Well if your hoses are like mine were. a couple years ago I had the same sort of problem. I had noticed for quite a while the lower hose where it is crimped on was wet, but not dripping. it always stayed the same. I always thought the rubber was sure hard stuff the germans use.

We were on a trip coming home across Hwy40, think we went to Dallas, Tx. we stopped just into calif., I was checking under the hood, and the damn hose was dripping ( Just a little) so kept a eye on it all the way back to Santa Cruz. when we got home the inside of the L/F wheel was wet with oil.

The reason for the hard rubber is they had been on there since new. had a stamp in the crimp of 10/84. amazing how soft the new rubber is.

So these are not for the life of the car, they need to be changed out like all the other deteriorating rubber parts on the car.

So I don`t know what is worse, blow a oil hose, or have a timing chain break?

Good thing you saw it in your driveway. was there any dates on the hose?

No dates that I could find, but it was the funniest thing. I started my car and realised I forgot something and left it running when I went back inside.

When I came out, there was a little puddle under the front left and it was getting bigger. Then, a steady pouring of oil in a thin stream, so I popped the bonnet and there it was!

So since I just had to replace my climate control after it decided to eject all the buttons and inner parts and springs, well it might as well need this now too!

Was that hose in contact with anything where it wore out?

If so then what ye need in nautical term is "chafing gear" - wraps over lines to prevent em from wearing out:



In similar fashion if yer hoses rub against *anything* including another hose then they'll wear and eventually spring leaks. Even plastic vacuum line can eat fuel or oil hoses if it comes in contact.

Visual inspection aint enough, gotta reach into engine bay to find suspicious lookin vibration spots. Betcha find a few points where hoses wearin thin from loose contact with something else. My personal fave material for wrapping chafing gear is an old bicycle tube secured with fine wire or string. Though even torn strip of towel rag will help.

Probly one mfgr of oil hose is good as another says me. Question is what do hoses rest against.

These hoses didn't rub anything! Once I got it out and looked at it, it lokked brittle, so I cut it open and it literally disintegrated right in my hands!

It was right at the lower part where the hose goes into the lower part of the cooler too. Nothing to rub up against. Looks like it just wore out!

I just replaced the lines on my 300sd. Used factory hoses. I've read too many horror stories about using aftermarket oil cooler lines. BTW, I don't know the design differences, but I was originally using dieselgiant's guide as a reference. All went as listed until it came time to actually put the new lines in. His guide mentions taking the old lines down and out the back, and that the new ones go in the way the old ones came out. Well, after wrestling with the new lines for an hour and having no luck getting them in correctly, I looked at it from up above in the engine bay. With the motor mounts out, I was able to slip them in place from the top in about 2 minutes.. I was never so angry and happy at the same time..

Ditto! Although I didn't try the removing and replacing towards the rear of the vehicle, it was definitely easier with the motor mount out of the way!

Just as I thought! This repair where the PO had cut the metal tube to get the upper cooling hose in is making it necessary to replace this one too!

Of course the union fitting leaks now, I disturbed it!
