Having taken 11789 out for a few "shake down" runs which has included purposely driving in heavy stop start traffic, I have to say how impressed I am with the replacement DGo Radiator.
I was advised to change the rad and fans which I did.
I had a "grumble" about mating the main aluminium fan shroud to the rad, as a bit off fettling was involved.
But credit where it's due the rad performs great and at times I can't believe how effective it is.
I don't have the "other" fan shroud fitted, but I honestly don't think it's required.
I still have the original rad - but that will be consigned to storage.
