Hey guys,

I am planning on using seafoam on a 2005 ES330 with 200,000 km on it.

I have never tried seafoam on this car, and I was looking for the brake booster hose. There are some pics on this forum but it looks like it is for the ES300. If someone can describe the location of the brake booster hose for the ES330, or another hose to use for Seafoam, it would be greatly appreciated.

Thanks.

the hose going from the intake manifold to the brake booster...

remove from brake booster end [so tube going INTO the intake manifold] and let it suck it up that way

I personally wouldn't use a Seafoam Treatment on any Lexus.

Fully agree. Not a good idea. Not even needed.

Can only do harm, and not any good.

"Don't fix it if it ain't broke" is a good rule to live by. The first question is, what exactly is this going to accomplish?

I've used SeaFoam on older cars, and it does what it's supposed to, but it's also risky, especially when you pour it in directly into a running engine. It can clog things like you catalytic converter, foul your spark plus, contaminate sensors, etc. And that just off the top of my head. You could also hydrolock the engine or break up some sludge that bends a valve.

If you're concerned there may be sludge in your engine, I would start by maybe just pouring some SeaFoam in the gas tank and maybe pour some in your crankcase where your oil goes, then change the oil after a few hundred miles. It's much less "shock" to your cars engine that way.

Thanks for the responses everyone.

So what I did was use the seafoam just for the engine crankcase and the gas tank. Thus far, I have not used the seafoam on the hose yet. However I would like to attempt this the next time around. I am still not sure which hose to use for the seafoam. My initial thought is it should be from the Red circles hose (shown below).

Can anyone confirm whether this is the right hose??

Thanks.

There are several Videos on You Tube.

Just type Lexus Seafoam.

Seafoam can't do harm. Is arguable since it may not do anything but it wont harm the car. There are guys on this forum that seafoam many times a year with no issues. I've done it once last year and forgot to do it this year. I noticed a slight increase in fuel economy when compared to last year factoring in idling in cold and whatnot. Perhaps it's my mind thinking it's beneficial.
