Wiring protector under coolent tank damaged
Hello. Anyone ever seen this? when I was putting on my DRM shocks (before it got cold), under the coolant tank the plastic insulation was all messed up. Is this common? I'm thinking of using some type of insulation but NOT the OEM plastic. Good idea?
Does everyone's C6 do this or was my car overheated?
Anyway, I thought I'd share it. Pretty strange. (I know the wire recall for the low beam is an issue I'll see the dealer about, but maybe they can check this too.)
2008 base z51 with 55K miles.
Thanks
(If the photo attachment doesn't work, I'll pasted it in another way)

Don't know the answer, but mine looks like it has never been touched when I changed shock a few months ago.
I do need to qualify a few things, first, the only time my car has seen in snow, it was inside a trailer or on a roll off truck, so effects of weather on it.

There are grades of split loom wire protector with price proportioned to degrees of protection and durability.
I prefer the Coast Guard Approved Marine Grade Crosslink constructed protector.
Out in the ocean, you don't want to deal with fire - good enough for me.

Just snip off the broken area, and replace with new wire loom of the same size. It's available in all auto supply chains. Mine has 55+K miles, and still in great shape. I wonder if someone hit it with something to damage the loom. As long as the wires themselves are not damaged, no issues.

Thanks for your replies. I didn't even know what the stuff was called. So its good that it is a relatively "normal" problem from heat and age, and not something that indicates something worse.
I will do as recommended and not replaced with crappy plastic stuff. the Marine stuff sounds good to me.
Thanks again.
(I'll wait a few months - 15 degrees this AM, had enough snow for this year and next. Spring can't come soon enough.)

I live in South Florida, my car has only seen winter when I picked it up in February at the Corvette Museum, well real winter. Not Florida winter. :-)

The loom comes in different materials with different temperature ratings:
-40° to 200° F: Polyethylene (Black)
-40° to 200° F: Flame Retardant Polyethylene (Gray)
-40° to 275° F: Heat Stabilized Polyethylene (Black with Green Stripe)
-40° to 275° F: Flame Retardant Polypropylene (Black with Blue Stripe)
-40° to 300° F: Nylon (Black with Gray Stripe)

I believe these colors are probably standard. They correlate to what I've seen in person at electronics suppliers.
I used nylon split loom over my radiator. For what it's worth, I noticed that Ferrari uses the green stripe loom near their headers.
The other question is what to tape off the ends of the loom with (I'm referring to the _outside_ of the loom, not the wires themselves, which are often wrapped with a non-adhesive tape).
Chevy uses an adhesive tape with a woven backing at junctions on the outside of the loom. Almost like friction or duct tape. I never found an exact equivalent that was rated for high temperature, so I used Tesa #51026 wiring harness tape. I'll let you know how it holds up.
Some people suggest self-fusing rubber tape like 3M Temflex 2155, but this doesn't strike me as a great idea because 1) it fuses together into a lump so it must be cut it off and 2) the loom is split, so there's no point in a hermetic seal at the ends.

^^right on!^^ need to understand application specifics. Much like battery cable, any wire will work, but some is better suited for efficiency/longevity.
For securing wire loom end even though it has a split...for me, it is more of a tidy packaging. I duplicate OEM style while wrapping with self vulcanizing and dust resistant silicone tape. I use it on all my wire splice/end:
Silicone tape along with Marine grade adhesive lined shrink wrap, together, assure an environmental seal:
