Jumping on this thread -
So I redid the entire cooling system on my 2010 LR4 5.0 as part of my engine rebuild. I bought OEM parts from Atlantic British...we will see how things hold up.
I have posted in other threads about the issue from my "Amazon" water pump....

So a lot of support for the highest quality parts from my side.
All that said, this YouTube video came out this morning from Wraptor Customs and Tuning in the UK:
I posit this to the group because he mentions a lot of aftermarket (metal) parts to replace many of these plastic bits for the cooling system. Unfortunately, he is specifically talking about the turbocharged engines (problem for our 5.0L folks)...but perhaps they supply for 5.0L Normally Aspirated or most of the components are identical?
Just a thought and maybe someone has experience with the metal components, such as several of the brass fittings mentioned in this thread....
