I think I have this leak. What's the solution? Do you just have to replace the hose, or do you have to replace the reservoir?

I dropped it off at the dealer and they replaced the hose and clamp....but I think it's the clamp that actually loosens over time.

just a note...I had an alternator rebuilt at a local automotive starter, alternator shop. He replaced everything for $100.
if you purchase from Rockauto or a local Autozone etc, they are almost all rebuilt. Rebuilt means they fixed the broken part and everything else is used.

Along the lines of this, my power steering leak probably took out my alternator, I didn't even think of that happening when I first noticed the leak. I agree with your opinion that a local rebuilt is likely better than a "unknown" rebuilt from some company.

You mention that your in Florida, any chance that your in South Florida?
There are so few shops around me that I would trust so a referral would go a long way.

I am in central Florida, I-95 MM200ish. I took mine to a shop in Titusville.
did a google search for alternator starter shops.
i asked him to replace every part available.

Thanks for the response... I am way south of you, about a mile north of the Miami Dade Line. I did talk to a couple of local shops and they were about $60 less than my Denso Re-Man but neither of them gave me a sense of confidence that their rebuilds would last as long and who knows if they would be around to warranty it...

Ask the shop what they would replace...or ask them to replace everything.
bearings, diodes, voltage regulator etc.
typical rebuilt means, replace bad parts and paint.
just understand the difference.

i think Rockauto.com sells a new one for $150.

It is as easy as getting a certified re-manufactured Alternator carried by the Auto shops. They do test them before they get a seal. And the warranty is good.

I have this leak. Anyone know what hose I should buy for replacement? I can't find a Lexus specific hose. It looks like I just need to get some generic hose.

I plan to remove both hoses and see if autozone has appropriate cut-to-length hoses to replace with.
But from my time with my Vanagon, I've learned Oetiker clamps (ear clamps) are the only way to have a lasting secure fit.
Will be doing this replacement unless someone has any reason to advise against! It looks like both hoses have clamps at each end for the first sections where the leaks occur.

Ear Clamps are probably a good idea. When I did it I used common hose clamps, but the two hoses are pretty close to each other and it was hard to get the to screw down properly

Yeah actually I checked last night and there are indeed clamps on each side of this hose. So I found some 3/8 ID Gates (part no 350010) power steering hose that I used for my 80 series Land Cruiser. It looks like the right size. I'm going to order new OEM clamps from partsouq.

There's a part number for the other larger power steering suction hose as it's formed I think. I had replaced that one about a year ago because it was leaking.

Make sure your hose is SAE J189 compliant, at least for the smaller diameter return hose.
