My old Rangie started suffering from a knackered radiator some years ago, about half its surface staying cool from blockage, a couple of bouts of flushing barely touched it so I made a mental note to replace it sometime. So after 5 years of not exceeding 80 as the temp gauge would start to climb I last week had to reduce the limit to 70, and it was starting to struggle with the 2 hours at tickover M25 crawl, so has a look, £175 for a cheapy one with the crimpled on placcy tanks, or £115 for a 3 core all metal jobbie from China, I took the gamble, and it's quite a nice rad.
Not quite straightforward though, two tabs that hold the cowling are on the wrong end and upside down, easily resolved by cutting and pop rivets.
Big problem was the transmission and engine oil coolers, on original rad there's four unions screwed in, the engine side of the new rad takes them, but the transmission side has pokey out male fittings welded in.
So should just mean leaving the unions out, only it's pairing two convex flares, albeit both with a good bit of square surface to meet, I couldn't be arsed to put the old rad back in and send this fucker back so I dug out a couple of copper washers to stuff in, but then considered that I'm bolting steel to aluminium, no need the copper, slathered on the thread sealer and seem to have got away with it. Probably look into adaptors or bypass it sometime but ok for now. Verdict, uprated Chinese rads are well worth considering, but be ready for issues.
