Oil Cooler Hose Failure

What started out as a drip is now a stream! The nefarious oil cooler hoses have now failed fully as evidenced by the pools of fresh oil adorning the garage floor, driveway and various parking lots!   I have ordered the new hose ensemble from Jerrys Gaskets.  The cost with shipping was $179.00.  The hoses were shipped very quickly and arrived today.   Four days from OK to ID, not bad! The hose assembly fit perfectly and is designed very close to original. I give Jerry's Gaskets an A+. They also have a growing LT5 parts catalog. As our C4 ZR1's get a little more broken in, it's good to have parts!

The replacement of the oil cooling hoses is very simple and takes about 20 minutes to complete.After you are done, run the engine for a few minutes to make sure there are no leaks.I had a minor leak from the bottom hose but torqued it a bit more and that fixed the problem. 

Old oil cooling hose assembly removed.

Attempted fix with rubber tape and hose clamps.

This meager atempt to salvage bad hoses does not work, at all.

And I am embarrassed to even show it...  I've always tried

to get every second of service life out of parts. 

Sometimes not a good idea however.

Radiator side of hoses. The new assembly comes with new O-rings.

Take care when attaching the radiator side to make sure the O-rings

stay in place.  You don't want a new leak with a new hose!

Note: This is the old hose assembly.

One bolt holds the assembly to the radiator.  Place a shop rag underneath

the fitting when removing the bolt because oil will leak once removed.

Of course it is not under pressure so the leak will stop quickly, unless

you kept the engine running...

When removing the old hoses from the engine. place a shop rag underneath

the hoses to soak up the oil that leaks out.  Avoid getting oil

on the belt which is in close proximity to the hose attachments.

When attaching the engine side hoses, you will need to install the

bottom first because there is not enough room to fit the wrench with

the top hose attached.  Yes I know, that's pretty obvious....  :)
