Fuel cooler radiator replacement defender puma 2011

Morning all. my fuel cooler rad is leaking and I’ve sourced a replacement, is there any special things that I need to know before replacing. Does the system need bleeding etc ??

You might need to to bleed the fuel system. But as the cooler is on the fuel return side you might be lucky and not need to. There is a thread in the Engines - Puma section of this forum, dealing with bleeding after an oil filter change. Not many threads in that section, its near the bottom of the first page. Read through that to get an idea of what is needed.

thanks so much !!!!!
