Will there be any problem with the radiator hose running over the top of the ran rather then the side??
Here is a photo of the hose on top of the engine on my 52 P23 if you need a photo of the other side let me know.

as long as it fits no problems , but i would take some measurements first, it looks to me as if the 52 radiator is taller than the 53 ,i have a 54 which is virtualy the same as the 53 and i'm not sure if you would get clearance with the hood
