Thanks Rovernaut should be running again in no time - cheapest I could find new online was $80.Quote:

I blew the header tank last night, luckily I heard a hissing under the bonnet and it is only a little split. I m just about to look at it in daylight.
Has anyone tried an alloy one?

Looks a nice bit of gear, but from what I can glean from here, something else causes it.
I routinely clean & silicone lubricate both valves in the cap.
A leaking head gasket is something else that I cannot do anything about though.
I think ill email the Myth Busters;) , Im still running the black expansion tank , 3 years since i bought my Defender , And yes its a everyday driver
I have no idea how long its been on the car , I never loose coolant and i have a engine saver aswell so im not going to follow the sheep:2up:
I replaced mine after 8 years with a white one and when I bought it they would not give it to me without a new cap.The tanks are splitting because of pressure and that is the caps job.I don't think an alloy tank would help,it would just move the problem to the second weak and probably more expensive point.

I am touching wood as I type this but my RRC 3.9 black tank is now 16 years old , with no obvious problem.
I replaced the coolant today with a demineralised water flush.
checked the low water alarm and it is OK.
Maybe it has something to do with having clean coolant in it.
I use Nulon Longlife and change every three or four years, or if I do a headgasket LOL.

I rang my nearby LR guy (Ayers Automotive) and thankfully he was,
1. Open on Saturday.
2. In possession of a white expansion tank and cap.
So I fitted the new tank and hopefully this one will be good for 10 years or 200 000km like the last one.

Ive been reading all this and::
I believe that you can add a dye to the coolant to see if you have a gasket problem
Talk to the head exchange people
Also i had this problem (drives great in the city / boils under load, heavy sand 4wd)
Installed new 4 core radiator / Still happened / Temp gauge registered half then steam everwhere
I had been trying out thermo fans in lue of standard fan
Turned out to be wrong thermostat (was 92c)
Changed thermostat (72c)
Got rid of the thermo fans & went back to originals
Now everthing is rosie
So check that you have the correct tempreture thermostat setting
Mike, if you really mean 72c and not 82c, I assume your car is a 90RR, then your injection will be adding fuel all time, as it thinks the engine is cold starting. The cut off for warm operation is 80C.Quote:

The thermostat if operational has little to do with overheating. the car should run well with an 82C (although I think it is is a bit near to 80c on a cold day), 88C ( which is what was fitted new), or 92 c.
So 72 C is no good for an injected car. OK for carbys though so if my assumption of 90RR is incorrect, ignore me.

have been reading this thread with great intrest. From what you guys have been saying it looks like this is what has happened to my 300TDi disco. Was towing heavy trailer on a warm day temp gauge was normal whole trip untill it suddenly jumped off the scale. The bonnet lining was soaked with coolant above the tank. I have not had a chance to look at it as had to fly out to QLD the next morning and wont get a chance for a few more weeks, just hope it has not seized the engine like i suspect it may have.
Is this the same tank as what is in the v8?
