Dan at Krazy horse mentioned that the radiator has been fixed by replacing the cap with a lower pressure rating. Can anyone confirm if it does fix the leak issue and how can you tell by looking at the cap if it has been changed?

I think the lower pressure cap is combined with not topping up the header tank too high as well ?

So, as I see it a WET system that becomes hydraulically locked by it's OE design...and blows things apart... doh

I'll go with that but surely this should have been remedied during the road testing period, I find it hard to believe MMC were not fully aware of these problems prior to releasing the cars to the public - again nono


The times I have counted my blessings by staying with the Plus 8 and not changed to a Plus Four you wouldn't believe.

My good lady suggested I got a new car last year bless her and I did a lot of homework but the sound track of the V8 faulty radiators and uncomfortable seats killed it off big time for me. To me both these faults had nothing whatsoever to do with it being a hand built car, just poor development prior to release.

To me both these faults had nothing whatsoever to do with it being a hand built car, just poor development prior to release.

I had my doubts at first such that I ended up with a 22MY car. To answer your three points:
1. If by soundtrack you mean a V8 versus anything then I would have to agree. My Roadster with AR exhaust sounded pretty good but obviously not a V8. I have the standard exhaust which pops and burbles in Sport and Sport+. If I had the choice again I would probably go for the switchable/valved system. If by soundtrack you mean the bluetooth then I could probably blow the doors off with mine as Headless Blue will confirm.
2. Touch every piece of wood and cross every finger but as yet I have had no problems with the radiators on mine. There is probably a pool forming on my garage floor as I write this
3. I have the Comfort seats which as it says on the tin are very comfortable. Having subsequently sat in a Plus Six with Comfort Plus I would probably go for them as they are even better.

Having said that as we all know MMC are serial offenders when it comes to releasing cars that are not properly designed, tested, etc.

On that note, everything has gone VERY quiet on the Super 3 front. Does anybody have any news?

Thank you John, I am really pleased for you that your car has behaved well.
By sound track I was comparing the V8 as opposed to the in car entertainment, my Plus 8 came with a Becker set up which I only turn on when I'm fiddling in the garage.
It seems crazy to me that you can release a car onto the market with uncomfortable seats and that you have to in effect have not one but a second upgrade in an 80k car.

Who knows I might get one sometime in the future when the LHD knee finally gives out and I can no longer do my own maintenance etc, I'm happy in a holding position right now. Exhaust upgrade noted..

I appreciate your explanations though John, thanks for taking the time and enjoy this lovely spring time weather.

Last time i went to garage Albert was to take a picture of radiator leaking again.

They put the new radiator cap and untill now the leak has not increased.

Only one small drop on the garage floor.

If this is the solution , they have lost a lot of money changing

Dozen of radiators.
