Hey guys, i did my rack swap a couple of months before and this one issue keep popping up, the power steering is fine and light when the car is cold (i.e the system is cold) then after I drove it for a while, the steering get really heavy almost like no power steering) idk what might be the problem. I suspecting it might be the line(how i route it) so if any of you have done it pls let me know how you guys route it

What fluid did you use? It sounds like it could be thinning out or cavitating when it gets warm. What PAS swp did you do?

Hoses as they get hotter get more flexible, depending on how you have routed the hose it could well be kinking over and restricting the flow of fluid which would result in next to bugger all power assistance
