I had changed the power steering fluid on my truck to royal purple using the emptying the reservoir with a syringe and filling every week till i swapped the the full capacity the system holds. I would spill a little and would clean up what I would see every time I did it. But when I did my oil change I noticed that the hose that's directly under the reservoir has oil residue on it so I thought maybe I forgot to clean it, I wiped it clean and checked again today and it has residue again. It seems like it's coming out through the top of the hose as there is a little tiny build of oil around the top of the hose. But not sure how that's possible if the end is facing up and the clamp is on there. Could it be the bottom of the reservoir?

No one?

Having a wet spot doesn't tell much. Buy some dye at the auto supply. Put the truck in the garage or under some good shade. Put 8 or so drops into the reservoir. You'll need the yellow lenses glasses and a UV flashlight, but after you cycle the pump for a few minutes, the die will glow at the leak when illuminated with the UV light. Yellow lenses make it 'pop' so you don't miss the leak point.

If I had to guess I would say it is coming from the clamp. Those spring clamps fatigue over time and let fluid come out. All of mine on the transmission hoses were fatigued, one to the point that it had let the hose come almost all the way off the barb. Most people just replace them with worm clamps or add a worm clamp and still keep the spring clamp.

Going to try the replacing worm clamp first clean it up and see if it maybe is the fatigued clamp and get report back

Those hoses tend to go south on Nissan products. I've changed a lot of them they're usually easy.

Yeah it was the oem spring clamp, put a hose clamp on it and its dry since!

No surprise there! Those OEM clamps start losing their moxie after awhile.

The high pressure line/hose is most likely the culprit.

it's VERY common for them to leak at the crimp near the power steering pump.

Did you ever figure this out?

He sure did. Look about 3 posts above this one!

:eek_surprise: How did I miss that ?
Thanks!
I've been planning on upgrading all the clamps on the engine, I better do it.

Armada guy here - I have had that exact same leak for over a year on my 06 LE. A new worm clamp did not solve the problem - that bottom hose is always shiny. In a year I have added back maybe an ounce or two of fluid, so it doesn't leak much but its just like the one pictured here. I'll replace the hose at some point. It looked ok but I assume it has a crack somewhere near the clamp area. Either that or the reservoir itself has a crack.

Has anyone had a problem with the reservoir leaking I have put a warm clamp on there and still see moisture around the top of the hose.

New clamp on old damaged hose (hard, brittle, crushed, cut, permanent clamp indents) doesn't always stop a leak. I think it's best to use a new hose (or cut the damaged end off of the old hose) and a clamp of a type that doesn't damage the hose.

looks to be a 3/8 hose?? sometimes a new clamp can fix it...i think it all depends if its found quick enough/early enough as the trans fluid itself outside the hose will break it down. if it found a leak path its hard to seal that up.

I have discovered a leaking hose...reading of recalls on some maranos...hope the pump is okay, its the lower one ,drivers side.
