Hey guys,

Leaking power steering pump. Seeing as how these PSP's take ATF, then wouldn't Lucas tranny fix be the right additive to give it a shot before replacing / rebuilding?

sorta makes sense, no?

 

I had a decent leak on an 88 1st gen runner and I threw about half a little bottle of lucas power steering stop leak in it and it never leaked another drop. I even kept it through doing a sas and 37" tires, never gave me a single issue.

 

Yeah I'll definitely try it.

Although I was asking if it's better to use transmission fix vs. power steering fix, seeing that this power steering pump takes ATF and not power steering fluid.

 

I just got of the phone with pple at lucas, they suggest power steering fix too.. so i guess I'll go with that and let y'all know how it goes!

 

I tried Lucas on an Oldsmobile one time, and it did not work. Also tried Walmart Supertech power steering stop leak, and that did not work either. Replaced the pump. Wasted money on stop leak.

 

this statement is subjective to what is leaking in the pump. Saying stopleak doesn’t work is t really true, unless there are no seals left at all to swell. His leak may just be an old seal somewhere, like I had, and Lucas could hold it over for long enough.

 

They're pretty easy to rebuild also, less than an hour I'd say. Kits are $10-15 online.

 

Guys, just don't use any sort of stop leak.

They tend to make a mess of the system they are put in, even if they do stop the leak.

I would suggest to skip any sort of stop leak type of product and just rebuild or replace the pump.

 

There are two basic types of stop leak (magic in a bottle). One being particulates intended to lodge in the leak, the other is a seal conditioner to rehabilitate dry or damaged seals. The first one tends to gum up or damage bits you'd rather not have to replace, the second has a far less chance of damaging rotating parts but still has a chance of sending a bit of the "swelled" seal thru the system.

Given the time space and tools the pump reseal as.mentioned above is fiscally prudent.

 

This. Never heard of stop leak of any kind that works for real. Its all snake oil. Replace leaking components and be done with it.

 

I had a leak and it just ended up being the o-ring at the hose elbow inlet. Easy fix. Had a horrible leak in an Isuzu truck and Bars Leak actually worked.
