Well this was the explanation given by Morgan Belgium . With the new software the closure or the opening of electronic valves are delayed. Now when they check the radiator if there is a few drop of coolant

the radiator is changed and the waranty extended 2 years (on the radiator). On my 5 radiators i had always only few drops sometimes with nothing on the floor. The radiator seems to be well built and is very

heavy. My car has now 25000 km and since february 2024 the radiator is not leaking . I am crossing my fingers.

Even it is annoying i can't complain about Morgan or garage Albert because they fix the problem at there own cost. It is 12 hours work and it is a small garage with only 3 technicians.

I have one of the first made plus four ( july 2020). Since 2020 the plus four has been improved a lot after the remarks of the customers.
