Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) Plus Six radiator failure - again

It is not a problem just restricted to P6 is it, P4 have the same issue with a different engine and radiator.

Not every CX as had a replacement radiator although reading some of the posts on here you would not believe it. Yet some cars have had multiple rads, so why do some fail and others do not? Does anyone know for certain the radiators are being replaced with brand new rads, or are they just repairing the rads and it it is the repair that is falling? Could explain why the car with 10 replacements are in fact the same radiator.

Looking at the business mentality, it would seem odd to throw nearly new radiators in the skip. I suppose it depends what the dealers do with the old radiators, but you would think they would be returned to MMC, and that MMC would return them to the manufacturer.

If the manufacturer is churning out new rads and skipping the returns, you do wonder how long that is a sustainable business model.

We may never know the truth, but having a CX out of warranty with expensive issues like this will affect the used market. At least for those who know.

Every 'proper' motor manufacturer spends years, millions of miles, hundreds of millions of euros/dollars/yen developing new models.
The tried and tested Morgan method for years has been build it, tweek it, fiddle with it, sell it, and then let the new owners do the development and testing work.
Legacy owners (trad owners) have always been pretty happy to go along with the old way. At £80k+ new owners rightly demand that their cars are serviceable and reliable.
Come on MMC get a grip....!!!

At MMC, they are real Magicians
They manage to transform customers' automotive passion into deep disgust for the artisanal automobile
It's really a pity.
For this radiator problem, isn't there a more robust Mulfab type model?

The fact that it often costs a lot of money to develop a car, sometime hundreds of millions can be seen as evidence in the fact that something as seemingly trivial as a stupid radiator cannot be fixed. A large manufacturer would probably be able to invest a lot of money in test runs regarding vibrations, thermal challenges, pressure, flow, ECU control etc etc. So it's not such a trivial thing to just take a radiator and put it in.

I understand SiFab was developing some upgrade, but sadly the company folded

I don’t post a lot on here and I am often careful what I say . My 19 plate ex press Morgan car is due its second MOT next few weeks, and a yearly service. All done at Morgan HQ. I don’t warm the engine up and I don’t cool it down. I do thrash the car , I treat it mean, I drive in sports mode most of the time. It’s done 25,000 miles, nearly, and I post here to say that all the plus 6 cars can’t all have faulty rads etc, because I have never had a problem. Even before the enforced rad changes we had last year , mine had zero problem. Could anyone else post on here to admit they have had a problem free car. Mine can’t be the only one. Or am I just super lucky.

Radiators 'failing' is not a problem on BMW vehicles, with the same engine. Forget 'thermal shock' and the like, this is down to radiators simply not being up to the job...

I would bet if a top quality aftermarket market alloy rad was fitted...there would be no concerns?

My mate with a TVR had an alloy rad fitted last year 5 litre engine car situated in a very hot environment - since fitting no problems at all (I think he said the rad is made by AlliRad) and the car is tracked.

Sorry Morgan but this is just down to poor quality radiators...someone (with an out of warranty CX car) is going to cook an engine anytime soon and a modern Plus Four or Six (BMW engine) is going to be 5 figures to replace...will Morgan stump up?

BTW - I have tried a Plus Six and would really like a (second-hand) one, however, reading all this does nothing for ones confidence and hurry to part with £50k, or more......!

Jono

Happy to confirm I have NOT had a radiator problem. 2021 car with sadly only 3k miles.

Cheers

Ian

Okay Ian, your almost new car has had no problems. But the sheer number of problems others have must be disconcerting, right? What about in a few years, outside of the warranty period?
