the hoses are around 38$ each OEM
i got the fluid resivoir locally for 26$ ZF
resivoir has a non replaceable filter in it so changing it is good

you will need 4 hose clamps

i did it myself took an hour, be careful with the upper radiator small hose, where it connects to the top of the radiator hose is a plastic small line that will break if you havnt changed it before (mine did with the slightest touch of my arm)
