Pretty sure it also heats up at high RPM, because the pump is smashing the fluid through the circuit like no tomorrow... even just the pump friction at 5000 engine rpm will produce a hell of a lot of heat in that fluid, which isn't good for plastic tanks, rubber lines and o rings..

I think

correct, the pump is geared (through pulley ratio's) to work properly at low RPM. there are numerous reports of factory plastic reservoirs failing due to heat in cars used for track day/club events and these guys only do a handfull of laps at a time

It's as easy as anything, just snip the low pressure return line (normal hose held on to reservoir with a hose clamp) and fit any sort of oil cooler in the gap. You may need to purchase a length of power steering/ auto trans fluid low pressure hose depending where you want to mount the cooler.

hi all dont fit a power steer cooler fit a filter there is no need for a cooler i fit a power steering rack evry day plus a lot of other stuff

just put a filter on maby a new rack too i never see racks ****ing out from heat just bad fluid

i only see like 1 car with burnt fluid evry 6 months

so all you need is a filter

if you a burning your fluid all the time then use a cooler

Yea that'd be best, but I'll probably mount mine on the strut tower near the PS pump itself
if you were to bolt it in front of the radiator, then would you need more fluid in the system as it has to travel further?
