This is after polishing water pump passages with Dremel kit that arrived today... I removed 90% of roughness using Dremel 80 and 120 grit flapwheels, along with Dremel finishing buffs.

1998-2000 LS400 water inlet housing...you can't see through to the other side..and coolant has to navigate around two 90 degree bends....requires extra engine power...even at low RPM

The LS430 water inlet housing is much more efficient,..you can see through to the other side although mass produced and still room for improvement...some sharp edges that will Dremel away. The boss at near lower right does not have the LS400 minor coolant tube..but it is there to accept a brass nipple after drilling and tapping..

Back of climate control head circuit board...crusty at all through hole solder joints with crust migration across traces in some places. Worthwhile to inspect.

Bulb and socket assembly sold as a unit... Slightly tarnished bulb... you can buy raw incandescent bulbs to relamp but not worth the effort.. The color filter cap is reusable but unsure at this juncture whether it is included with the lamp/socket assembly or not.. The other thing is I noticed all of thes cap filters were not fully set on the bulb(air pocket at end) This will interrupt illumination.

Lamp color filter is taller than bulb so you get an air pocket at the end and the color filter. This can become more of a barrier to light rather than a color diffuser. The remedy would be to either fold to a lip at the base or IF you have really good eyesight a very sharp tool and a steady hand to trim the colr filter to proper length. Wet the bulb or inside of filter for ease of installation.

Main logic board with 11 capacitors...This board exhibited none of the solder joint crusting issues of the control head circuit board. ( Perhaps someone has a better industry term for "crusting")
