There are two radiator hose in first generation Lexus LS400. Since my car have over 175,000 miles, its time to get a new set. I got a new set of radiator hoses from a local Lexus dealer. The total price for the two hoses is about $59.00 plus tax. I also got a 10% off because I am a California Auto Club (AAA) member.
After I got the radiator hoses, I took it to a local aerospace shop and have them put in stainless steel braided hose. I was going to get them from Summit Racing, but putting them on is very hard and lots of problem. I have the local aerospace shop inserted for me. The cost of it is not that much, however, the blue anodized blue end cap is about $15 each. Four end caps would run about $60 already.
The project cost around $130 and the time for changing them is about 1 hour. I have dealt with stainless steel braided lines for a while now and have some experience with them. Care must be taken for those braided lines.
To start, make sure your engine is completely cold and few basic tools will do. Here is the pictorial journey of changing stock radiator hoses to stainless steel braided radiator hoses.
This is a general view of the top (short) radiator hose. Each end has a spring loaded clip.
Make sure the engine is completely cold and use a plier to take out the clip.

Before you push in the new hoses, make sure to spray some WD-40 into the hoses.

Here you have it. This task is pretty easy and you can easily do it with in an hour or so. If you have any comments or questions, please feel free to contact ME! With $130, it sure make your Lexus LS400 engine bay look a lot different from the rest.

I have been doing most of the R&D and technical write-ups by
myself with my personal money and literally thousands of hours of my time. I have taken extra steps to
demonstrate in details how things are done. Currently I am
one of the few people doing Lexus V8 research and performance
enhancement. This effort comes from my personal love for
this wonderful engine. Most of the modifications are from
trial and error. There's no cookbook for 1UZFE
mods and its unknown territory for much of supercharger performance.
