Rrs 3.6 tdv8 water hose problem

Grahamsgl84 · Feb 23, 2020

Hi I am new to this am on my 4th range rover but this is my first sport it's a 3.6 tdv8 and I have a problem the top radiator hose blew a few weeks ago from the engine/thermostat housing so I had a new thermostat and hose fitted yesterday and out today it went again if anyone can help with a clue what it could be it would be much appreciated thanks

Hoses blow off either because they are no good and need replacing, the engine overheats or exhaust gas is getting into the coolant (head gasket failure)

It's a new pipe genuine part

And never had overheating problem

Also when you rev it the top radiator hose gets hard with pressure

I think youv'e answered your own question...water pipes dont blow off unless theres another problem overheating you'd see that on guage or hg fail pressurising system a sniff test will confirm that...

Well it sounds like it going to be expensive

Were you losing water before hose blew off...theres another way to check for pressure...weve got a kit that replaces cap on expantion tank and you pump the pressure up to see if theres a leak in system...last month showed pin hole in my vans core plug after it overheated

No was not losing any water before it happened

Was it replaced at a garage?
Was it discussed about reasons why it had happened?

Grahamsgl84 · Feb 24, 2020

Yes garage done it they also done the thermostat same time witch was faulty

Just had the sniffer test all seemed fine

Was this with the engine running and at normal running temperature?
What happens if you start the engine with the expansion cap removed?

Grahamsgl84 · Feb 24, 2020

I was not there when it was done was at temp because I drove it there

Hi

Don’t know if it’s any help but could u use an infered thermostat so u can go round the engine bay on the hoses etc to see if u have any blockages

also have u held the engine around 2,000 revs to ensure no air is in the system

alas don’t really know these engine it was just a thought

It's going back in on Saturday to get looked at found the egr thermostat was split so just going to replace that and see wa happens when u rev it now u can see the hose getting pressure in it if u drive the car normal it's fine it's just when u give it a boot the pipe comes off

That looks very much like a manufacturing defect to me.
