I need to replace the oil cooler hoses in my 2001 S10 ZR2 (they're leaking)
and found these on eBay.  I went to Schucks and looked at their Haines
manuals but I couldn't find any mention of them anywhere on how to replace
them.  Is there a write-up somewhere so I could do it myself and save some
money?  Is is that hard to do?

Link to the hoses:

Well, I just party answered my question.  I found this write-up which says
you can remove the oil cooler and hoses altogether...which would permanently
solve the whole leaking hose issue - which they supposedly do on a regular
basis.  It suggests switching over to synthetic oil, which I was planning on
doing anyway.

Anway, if someone that knows what they're doing (it's obvious I don't) would
please look at the write-up and tell me if this is a good idea.  Also, where
do the other ends of the hoses connect to?  It doesn't say anything about
that.

I have a 5.7 L and when they put in the new motor they did that too,
Mechanic said it is just something to leak and they don't put them on to
many vehicles any more I also run mobil 1 in it.

If your truck is a 4x4, it will be next to impossible to get an
oil filter in there if you perform that modification.

"If your truck is a 4x4, it will be next to impossible to get an oil filter

Thanks, Ian.  I just figured that out myself actually.  I started looking
around and it pretty much looked not-doable.  So I took it to my mechanic
and he told me the same thing.  4x4 models have to have the oil cooler in
place, it's not something that can be easily bypassed.  The eBay seller with
the hoses was not able to tell me if they are the GM upadated ones that
don't leak.  So I'll just have my mechanic order the newest version (he said
they've made 3 different updates) and have him put them on.  It'll run me
about $300 total.  Oh well.  I read on automotiveforums.com that there have
been no leaking issues on the updated hoses...yet.  I'll keep my fingers
crossed.

Thanks for everyones help.

You can do it my 89 k1500 had the oil cooler lines removed with no change in
filter location, I believe the mechanic plugged the holes with some brass
plugs or something haven't looked to close to be sure.

My mechanic told me exactly what everything looked like without even looking
at my truck.  He said he's done at least a dozen cooler hose replacements.
He told me there's no way to bypass them because all the engine oil goes
through the lines via the oil filter.  Of course, I'm no mechanic, but from
what I saw under the hood it made sense.

I really don't know I just know they took them off and pluggd the holes, The
guy has been our families mechanic for over 25 years so I trust him and it
has been a year with no problems. Guess each mechanic has his one version of
what can and can't be done.

You have a different vehicle.  Even though your truck has oil
cooler lines, the oil filter is not "remote".  It still sits right by
the engine block.  So in your case, it's simple to remove the
oil cooler lines, and install plugs in the holes that remain in
the existing oil filter adapter.

The other poster has an S/T truck.  There isn't enough
room between the engine and the front differential to
be able to get an oil filter in there.  Which is why these
trucks have cooler lines coming from the engine block,
up to a remote oil filter mount....then another set of
cooler lines that head on up to the radiator.  Even on
the older S/T trucks, the filter had to be remote because
of the space restriction...so there were hoses that went
to the remote filter, but no further hoses that went to
the radiator.  GM just needs to get their act together
on the hoses they supply.

Yep.  This is my exact setup.
