DowA, I got my SI V8 Disco replacement one from RovParts (Part no PCF101590) and it cost me $110 + GST. RovParts is at 99 Muller Rd, Hamstead Gardens so not really in the city, but Doug couriered it to me (with a drive-shaft doughnut) in Blackwood for a whole $7.50. Doug's very helpful and I have no hesitation in recommending him. (Pricing is from May '07 so may be out of date btw.)

I got my replacement tank from Gary4wd. You will find him on EBay and he might be on aulro too. @$75.00 and he delivered!, but he was coming to Canberra anyway. His quoted delivery was reasonable, and I have found him a reliable and reasonable supplier.

Just a thought.....

make sure the Expansion tank is higher than the radiator... then the Air will want to go to the Expansion tank and not get trapped...

Clarkster, with the Volvo one you will see the expansion in line is actually on the upper most part of the tank. On my fitting it is higher than the radiator.
On the OEM LR ones the expansion line is on the bottom of the tank and If I remember correctly is a little lower than the top of the radiator and it comes from underneath and has to push coolant to escape into the airspace
I went for a long drive in yesterdays afternoon heat and had the aircon running as well. The volvo one held up to the task.
cheers.
Ps at the cheap price they are you could could fit 2 in tandom, LOL

I sometimes wonder whether a slightly leaking sleeve or head gasket may cause the cooling system to pressurise with a high combustion pressure load, like towing a camper uphill on a hot day.

Have to be combined with a malfunctioning pressure bleed in the cap I suppose. But I wonder if the volume becomes too much for the little hole.
The blow off level of the cap should only be reached on "heat soak" after the car is switched off. If ever.

Well my modified Volvo Tank blew at the seem at the weekend.
I seem to have a likely exhaust leak into my cooling system that pressurises the system causing my tank blows. It's not over heating, just over pressurised.
:(:(:(:(:(:(:(:(

Looks like I'll have to pull the heads.

Sympathies - need a cheap replacement too NSW - Sydney

My tank split and spewed yesterday going onto the beach at Stockton - managed to limp home to Sydney with a couple of water stops. I was thinking pressurised system till I read this thread and found a pretty common problem!

Have to say I'd never heard of tanks splitting before - that's what the cap's pressure release is for - or so I thought!

Anyone got a cheap supplier in NSW????

Karcraft in Sydney has the for about $56.

Before I buy another one I have to fix the cause. So in the mean time I picked up another Volvo one from the wreckers for $5
