Best Answer

It is behind the thermostat housing on the nose of the engine block. It is in line from right to left with the oil filler cap. There may be another air valve associated with the steering pump but it is not the "idle" air control valve (IACV).

The starter is located on the top of the engine, at the rear of the engine. In order to get to it you will need to remove the entire intake system from the engine.

What does VCS mean on a LS400 Lexus?

Do you perhaps mean "VSC"? If so, that stands for Vehicle Stability Control... In my Lexus Owner's Manual it is Vehicle Skid Control... probably interchangeable words but 'skid' is a little more definitive for me.
