So I am dealing with an over heating issue, I have 1core alum radiator with 3 10" fans (cheap ebay stuff). I got tired of it overheating so I decided to replace everything (high flow water pump and tstat casing, mr gasket 195, zj fan clutch, 10 blade auxfan, champion 2 core)

I didnt had the mechanical fan so I went to u pull it and saw this.
FIRST PICTURE...who can explain this?

...after that I removed the thermostat on my XJ and found this...

BTW A shop replaced it last time.

No pictures. I usually tell people to avoid the "hi-flow" stuff as it often causes problems instead of solving them. I'm assuming 95 from your sig. 2.5l or 4.0l? Automatic or manual?
