2 4 V6 radiator removal

[Harris]

Hi guys 

Im stripping out my cooling system so dismantled my front end to get the radiator out

at the top left hand corner of the rad is a pipe that splits into two the thicker pipe feeds from the engine and the thinner pipe feeds from the coolant tank

they both feed into a plastic housing which attaches to the rad. I need to remove this to get the rad out but not sure how and don’t want to break it

im guessing it just twists out but don’t want to break it in case I’m wrong 

any ideas????

Also same assembly bottom right

ive found a metal clip that slots it I’ve removed both of them very rusty and I think might have snapped as one side is longer than the other

plastic fittings still not budging

Decided to replace pipes so cut them off
