Water pump pulley wearing my coolant hose. 300 tdi

So twice now my water pump pulley has cut my hose..... See red arrow on picture. THe first time I had to replace the entire bottom hose assembly which I purchased from RN. The new one is put together in pieces with seemless bands. I would like to replace just the worn part. And of course I need to figure out why this is happening. Is that hose running in the wrong place. There is a flat piece of steel (yellow arrow) with tapped hole. What is that meant for? Is there supposed to be something there to keep the hose away from water pump pulley? Help appreciated. See photo.

Difficult to tell, but think the hose is to short-the rub as a result its getting cut.
If correct, lengthening it by half an inch or so would cause the hose to would arch up and away from the bracket etc,

Ok, a few things. First, that flat piece of steel is a bracket that is designed to hold the hose up and out of the way. However, there is a piece missing. There's a small plastic clamp that has a tab on the bottom that fits in the eyelet that you see on the metal bracket - essentially holding the hose in place, but also up and out of the way of the pulley.

Second, even in addition to the plastic clamp I also used a scrap section of hose to go around the outside of the hose to "elevate" it even more away from the pulley (I just zip-tied this scrap around the main hose).

Can't post pics from the iPad (drives me crazy!), so if you want shoot me a pm with your email address and I'll send you some pics of my setup.

Replace the missing plastic clip that is designed to hold the hose out of the way and also add a zip-tie to the smaller hose that passes over this one. The plastic clip in itself is enough.

Call George at RDS

Same issue here. I'm planning to make a
bigger bracket, that will cover the pulley.

Those are such a pain, you would have thought LR would have made a bit more clearance here. All that you have to do is use a large flat ended screwdriver and bend the bracket up a little more. As others posted I also used a old piece of hose to insulate it a bit more.

I too have a metal bracket that is attached to one of the water pump bolts which effectively holds a plastic clamp around the hose and keeps it away from the water pump pulley.
I'm having trouble uploading pics but I will also be happy to email you 2 pics of my OEM setup (96 Disco) which seems to work just fine.

I had the same issue with mine, so here's a MacGyver fix. It seems as though the hose is actually a little short in length which causes it to hang low. So when mine finally rubbed through and started to leak, I bought a 3" long , 1/2" diameter piece of pipe (in the plumbing world it's called a nipple), cut the hose at the point of leak through, inserted the "nipple", hose clamped it and the hose was repaired. Even if yours hasn't rubbed through yet, I'd advise carrying the nipple & clamps as your not going to be able to run down to NAPA and buy a new hose.
