Help With Replacing Coolant On 2001 Ls430

[Ed Darte]

I am trying to replace my coolant and I have read everything I can find specific to the LS430 on doing this. I read the very useful post on changing coolant on the earlier model but the engine block drain plugs are obviously in a different location than my 2001. I have an alldatadiy.com subscription for my car but their manual shows two drain plugs that appear to be up near the top of the engine (one near the water pump and the other on the driver's side of the engine, near the top of the engine). The third drain plug, at the bottom of the rad I can find - no problem.

Can anybody confirm if the alldata locations of the first two drain plus are accurate? The alldata is a very crude drawing (see attachment). If anyone could post a picture or give clear directions on where to find I would really, really appreciate it.

I am wondering if there still are three drain plugs- maybe alldata is out of date? How good a job would it be if I just drained everything I could from the rad plug alone?

TIA,

Ed

According to the information I have there is only one engine block drain !Removed! on this engine.

Have a look on the link below for location.

Steve:

Greatly appreciate the help here. I will need to get back under my car to check this out. However, if I am reading this diagram correctly, I think there might be two drain !Removed!; maybe one on either side of the block, as I think the parts list shows 2.

Cheers,

Does anyone know for sure where the engine block coolant drain !Removed! are on a 2001 LS430? (Note not in same location as earlier model)

TIA,

Okay, just to close the book on this. I finally got under the car and found the two (in addition to the radiator drain) coolant drain !Removed! and they are nowhere near where the alldatadiy.com site says they are. The toyodiy.com site that steve2006 directed me to is much more accurate.

Not sure if this is the same location as the previous model but they are on either side, lower down on the block, just ahead of the bell housing and close to the catalytic converters.

In addition to removing the front plastic engine cover (under the car) you also need to remove the smaller cover that is a little closer to the back of the car to access them. Once found, they are not too difficult to open and attach drain hoses.
