Engine to Radiator coolant hose replacement

Gertrudethedefender · Nov 11, 2023

Hi all.

I had a coolant leak on my 1998 TD5 which was ever so slow. After tracking it down to the hose which goes from the bottom right hand side of the engine to the radiator, I ordered a genuine replacement from Land Rover themselves. It’s here and I’ve got it pushed onto the radiator end with the speed clip fastening it on, but at the engine end there is a small flange on the metal pipe I’m connecting the hose to. I cannot for love nor money get the hose over this rib. I can’t get the clip over, but the hose will not push any further on. I’ve tried the usual stuff of a boiling water bath and some washing up liquid, but no matter how hard I try I can’t get it on.

Firstly, I don’t remember seeing this flange when I took the hose off so I’m assuming it had the hose over it, but was I just not looking and the hose should only got up to this point? Secondly, if it is meant to go on further, has anyone got any ideas which would help?

Thank you I’m advance

It's definitely the right way round, is it? Maybe one end is a slightly different diameter than the other. I haven't replaced this hose on my TD5, but some of my other engines have hoses that are different sizes at each end.

Is there two different types, maybe wrong one?

Defiantly the right way round as Land Rover have labeled each end to avoid confusion. I did double check that the other end wouldn't fit incase they had labeled it the wrong way round but they haven't. Thanks anyway.

It was ordered by a land rover specialist garage and it was molded to the same shape as the one i took off. Also the two ends are labeled with engine and radiator so i cant imagine its the wrong one. Thank you anyway as it could well have been something that simple.

Maybe 10p and 15p engines have different outlet?
Pretty sure I saw two versions online.

Put some pictures up

This is the best I can get as the angle is difficult to get.

Does this help ?

So how far on has the rubber pipe gone on compared to the old one?
Usually there is a rolled edge on the outlet pipe and the rubber hose pushes over it.
Is that the rolled edge we can see in the photo or is that an actual stop that the hose pushes up to?

Anaconda · Nov 12, 2023

If the hose does indeed need to go over the rolled edge then move that clip further down the hose, you can't push them both on at the same time.
I have found that sometime it can be hard to compress the clip over the hose when hose is fully pushed on.
You could remove the clip from the hose, slide it over the metal pipe, push the hose on and then fit the clip from the other end, if that makes sense.
On occasion I have got rid of the clip and used a jubilee clip instead.
Above advice is just general not TD5 related, not sure where the pipe attaches on a TD5

The clip was over the rolled edge to start with and I tried to push the hose on without it being in the way. However, being hopeful it didn’t need to be pushed on any further I put the clip in place to avoid forgetting it and happily driving along until the pipe blew off later down the road.

So I took the pipe off quickly and in the dark thinking this would be a 30 minuet job so I didn’t look at the positioning of the old hose. It appears that the hose needs to go over this edge, however I’m wondering if it is infact a marker as to how far the hose should slide onto the metal pipe.

Take the hose off and take a picture, I am not familiar with that pipe or hose.
The rolled part of the pipe is usually pretty much right at the end of the pipe.
Hose would push over it, clamp goes over it onto the hose, the rolled part helps to stop the hose blowing off.
Should be pretty much the same on the other end where it attaches to the rad.

Gertrudethedefender · Nov 13, 2023

I can’t take the hose off for the time being as I’m at school hall day but I’ll try and do it this evening. The rolled part of the metal pipe is nowhere near the inward end at which it enters the engine but is also a good 2 or 3 inches from the open end. I’ve played around with the speed clips so know that I would need to take it off and move the hose before putting it back on, possibly before the rolled part. The radiator end is just a straight piece of metal pipe of about 3 inches in length with no rolled part that the clip has to pass.

Thank you for all these suggestions

Interesting the pipe on the other end isn't rolled. Should be something like the elbow in this link.

Yeah it’s an odd one. I put some coolant in it and then limped it to a land rover specialist not far from me. They looked over it and said that someone has added some pipe to the end of the original one and so the hose won’t push on any further. I took it for test drive quickly and it held pressure well.

Thank you for all your help

Glad it sorted, bit of a strange one.
