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I am wondering if there still are three drain plugs- maybe alldata is out of date?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
