Power steering and pressure relief

[EmpirE231]

Got a new power steering reservoir from kartek and it has a pressure relief port that can be drilled out. Got me thinking… do we need to have pressure relief on our power steering systems? Current reservoir was the basic HOWE can. Switching to a reservoir w/ spin on filter.

Depends on how much you fill it and if water gets in the system. The system on my Jeep is sealed, it hisses when opened, but it’s never leaked out, even when spending hours rock crawling (lots of heat) heeled over on its side. I occasionally check for moisture, but isn’t an issue.

PS messes suck. Keeping everything sealed is good to keep dirt out, and oily mess in.

We ran a P/S reservoir/filter with a pressure relief on our Class 1 car, but the car went 1000 miles at a time. I have the same HOWE P/S reservoir/filter on my car and no relief. Not necessary.
