Thread: Discovery 2 Td5 Cooling System Question

Sounds like an aftermarket hose. Only use genuine coolant hoses.

Jubilee clips aren't that great,they put pressure in different spots.
Use the genuine clips,they provide constant pressure around the hose.

The only other thought isn't good,maybe excessive coolant system pressure?
The TD5 is difficult to bleed,hopefully it was done correctly.

As kelvo said , genuine hose . Aftermarket is rubbish
Never had a problem bleeding td5 unless head gasket issue, but there is a procedure
Scarry , the way I read it is he used the original clamps as well as jubilee clamps,agree the factory clamps provide even pressure

If you are using red coolant , you have to make sure the stubs are smooth by sanding the corrosion off them. The engine stub seems to get particularly ugly.
I agree that the sprung clamps are best. I tried some jubilee clamps and they leaked more. Get the proper tool to fit them. They are <$20 on ebay.

I also found that the hoses leaked everywhere for a while then stopped leaking after 1000Km or so.

Thank you kindly for the prompt reply, I really appreciate it.

In response to your comments:

1. Yes it is an aftermarket hose. Simply because I order a genuine and was sent an aftermarket one but needed the car running so I installed it - in 'negotiations' at the moment with the provider.

2. I did notice a bit of corrosion/gunk on the end of the stubs and did clean that prior to the installation.

3. Yes I did use jubilee clips in addition to the factory clips.

4. I followed the bleeding procedure as outlined in the RAVE - is there anything else I should be doing in addition?

Long time reader but first time poster and now I require some information from the Td5 gurus as I am at a loss.

Now on to the issue at hand.

Recently, my top radiator hose decided to develop a small split and begin to drain coolant. So I ordered a new one and subsequently replaced it. However, after doing so and it appears to be leaking from all of the four connection points. I have readjusted the jubilee spring clips that hold it on and even added additional hose clamps in an attempt to stop the leaking.

After going for a decent drive it appears my additional attempts have been in vein and the system is still leaking. When I say leaking, I mean not pouring out but there is consistent dripping. Additionally, on the hose that connects to the top of the radiator, it appears the drips are coming from the fibers inside of the hose as well as from the lip where it goes over the outlet (if that makes sense).

This is the second time the top radiator hose has been replaced - the first time the bleed screw gave up the go and I had it replaced by my mechanic. I did not get it done this time because it seemed like an easy job to accomplish by myself and also to save some dollars.


So my question is am I missing something all together or could it be a defective replacement hose?


Many thanks in advance for the assistance - cheers!

Get a Silicone hose.
I have a Samco and no more
Stupid leaks.

Cheers everyone!
