I started my car the other day to warm it up and preserve the engine. The p/s pump now makes a bit more noise, so I have ordered a new pump, pressure hose and alternator lest it is also in bad shape.

I noticed the sound of air rushing out. I removed my engine cover and discovered that a hose that leads into another hose connected to the intake has ruptured. I have attached a picture with red ink going along the hose and circling the spot where the break occured... its on the left side of the engine.

My question is, is this the pressure hose that im getting in the mail, or is this a power steering return hose that i'll need to order also?

 

Try to trace the hose, where does ti go, i cant see ti from that pic and i have nothing to comapare it too. It looks like a vaccuum line since power steering lines typically run around, not over the engine.

 

If connected to the intake manifold, usually vacuum hose. Might be a dealer item.
Follow the hoses from the pump to the power steering rack and back. Also consider replacing the return hose if it is dry and cracking, while the system it apart.

 

I traced the hose... it runs into the engine right next to the power steering pump. I think its a vacuum hose, but its not the pressure hose, if im not mistaken, the pressure hose actually runs along the bottom side of the compartment and has a large "bulb" in the middle of it. Can anyone with a first-gen lexus V8 take a look at theirs to ascertain anything?

 

Resolved. I sent the picture to a lexus/toyota parts dealer and they said that actually leads into the power steering pump and it did rupture due to the new pumps pressure being too high. The part is $20.90 shipped.

 

good to hear. let us know how it goes.
