    You can't fix a high pressure hose. If leaking from the hose it needs to be replaced. If the fitting is leaking, you need to carefully examine it to determine why. There has to be a flaw, crack or other damage that's permitting fluid to escape.

SOURCE: Replace power steering hose on 2000 Jeep Grand Cherokee

Parts are not cheap. I'm not sure how hard it is to get to your lines but line wrench/crows foot are probably needed. They are like a boxend wrench with cutout to go over line.

is the radiator fan coming on and staying on, or not coming on at all?? i was having the same problem, and it turned out to be a fan relay switch which was pretty easy to replace. around 40 bucks, and maybe 30-45 mins.

No power steering and smoking from hood


[1]the power steering pump might have siezed up causing the belt to slip to burn on the pulley. [2]or the pump broke the shaft internally and some fluid is leaking out and hitting the exaust[3] a hose has sprung a leak and it is spaying oil on the exaust manifold

O ring is leaking from power steering pressure hose


I had the same problem. You can not replace that o ring. You have to replace the complete hose ***. They redesigned the hose to fix that common problem. To bad the customer has to pay to replace a poorly designed part.

2002 Jeep Grand Cherokee leaking coolant and power steering fluid


Just a heads up, $10 bucks will buy you a seal kit for the P.S. pump. I topped mine off for a couple months, then the oring on the high pressure line (from pump, front center) blew and dumped the reservoir in a matter of miles.

The line can be a stinker to get off, recommend driving the car for a few minutes to heat up the pump a little. Don't forget the 20MM wrench.
