Hi - I was told exactly the same thing about MY LC80 (or was I told to replace the plastic top and bottom with brass because the plastic was prone to splitting - can't remember?), but all I can say is I didn't bother and didn't have any problems despite overheating a few times. Then again, when I did overheat I always stopped to let it cool down, so maybe there would have been problems if I'd pushed it.
I did however take the advice to flush the cooling system out and to renew all rad hoses.
Here's where I went - overlandcruiser.net
Mostly tarmac, but enough bad surfaces in that lot to make me think 'if the rad was going to go, it would have done'.
