My 2008 4/4 1.8 had to have a replacement radiator when the plastic inlet top pipe fractured.
I just ran into the same problem, with my 2016 4/4. Came into the garage couple of weeks ago and there was a puddle of coolant on the ground and the reservoir was almost empty.
Called my dealer (about 150 miles from my home) to get some advice.
They would not want to commit to anything until seeing the car. So I went to a specialist
who works on Morgans since the 70ies. He identified the problem and told me that it all started, when MCC started installing the plastic-framed radiators.
He told me, there are some well made aluminum radiators on the market and gave me an estimate for the installation of one of those, but advised me to ask my dealer to make me an offer that would prorate the original radiator since it still was under warranty.
Called the dealer. They made an offer. But they would not deduct the plastic-piece (we don‘t do such wheeling and dealing (German word is Gemauschel)).
So I had the choice to drive the 150 miles (which really is my problem) with a leaking radiator, then wait - how long!? - for Morgan to decide the warranty claim. And then get the cheap piece of ‚let‘s cut the costs‘ back into the car, or pay a proud sum to continue my Moggie‘s life with an aluminium radiator.
Well, the car sits at the specialist nearby right now and gets his upgrade.
And I pay good money for a car under warranty.
Know what? I am SLIGHTLY disappointed.
I bought a new, bespoke car for around 60.000,-€ to avoid spending thousands in the first couple of years.
Ha, ha.
