You can not see this cut.
Run your hand under top hose on the botton
of hose. Mine was cut into by the fan shroud
fin. This cut is so deep it needs replace.

Place your hand under the hose.
You can't see it. Only by feel.

The only way to see it is by taking off the hose.
Look at the middle fin then go under the hose.
I not saying it is on all the cars. On mine
It is cut deep.

On my 2.0 it is also not close but it is cut.
By that fin.

I checked both of our Redlines:

Both have the beginnings of damage to the hose where it contacts the rib on the fan shroud. Not bad enough to be concerned right now. However, I will be making modifications next summer when the weather warms back up.

I finally figured out what you were talking about. I checked mine again and the hose is about an inch away from that shroud fin. No damage at all on mine.
Maybe the redlines are a little different??
If you change your hose keep the old one, split open a section and put it over the new hose to protect it.

Mine is also 1+" away from the fin.
And cut. I missed it the 1st check.
You must put your hand underside of
The hose to fine it.

Only the 2.0L.

(Crosspost) I had the same issue. I tried slitting a piece of fuel hose to go over the fin, but it wouldn't stay in place. I didn't want to cut the shroud as someone else suggested, so I just used a long tie-wrap and cinched up the hose away from the shroud.

This shows where the issue is... see green arrow:



And showing the hose cinched up with a tie-wrap around the airbox clip:

Yep, no cut on mine. I can see how it would cut it if the hose was installed by the hose markings at the factory. To fix this slightly squeeze the clamps at the ends of the hose. Twist it slightly clockwise at the engine and again at the radiator. You will see a line printed on the hose to the radiator where it should line up and you want it slightly to the right of this. This will cause the hose to float up and it will be impossible for the hose to touch the radiator shroud rib.
The factory must have known about this because my radiator hose was clocked slightly clockwise.

FWIW....My '09 GXP Coupe has a woven plastic cover on the hose in that area!

May put some 'knock-on' over the fins.

black woven nylon jacket over the hose.

Replacing hose with DDMWORKS black rad hose.
Thank you.
Also the new hose will be tied down to stop the shake
going into the rad inlet causing it to crack in time.

Another one of those threads that sent me out to my car to check things out!

Apparently the woven plastic shield they used on the 2009s works as there is zero sign of wear on mine. I wonder if all replacement hoses now come with this, or if it is a separate part number? Anyway, it looks like an option for earlier cars.

I'd bet it's a separate part number. It's not a wear item so they would expect you to replace the hose when the time comes and just put the sleeve over the new hose.

You lost the bet.
09 they knew about it and never told us.

Looks like the best option for a fix.
Would be extra careful to not let any air into the system though
as that would cause some more serious problems.

I does show in 09 they knew about it and never told us.
So the hose and nylon protector are 1 part number? I was betting there would be a separate part number for the protector. And of course they knew about it, that's why they started protecting them in '09, they just didn't bother to give earlier model year owners any heads up.

yea, I just checked GM parts warehouse diagrams and they only mention upper rad hose, no mention of protector. Course they don't even show the protector as a part for sale.

(fixed it for me ;) )

no woven shield, but the hose has at least finger's width between it and the shroud; part may have changed with build date? her's is an '09 with a 07/08 build date

Finger's width is not enough. Mine has that too, but there's still enough flex for it to bounce against the shroud.
