C43 or other V8 engine coolant loss

[andrewcliffe]

I think I have a very small water leak. Have had to top coolant level up now twice in 3 weeks. Engine temperature remains consistant, can't see any obvious leaks or the sort of crystalline antifreeze type deposits anywhere. Car not steaming up or suffering from condensation.

Do these engines have any weak points that I should check first?

system was pressure tested and radiator was leaking slightly. Have swapped it out with a new one.
