In an emergency situation you can add water. But coolant contains anti-corrosive additives that prevent rust. Leaving plain water in your engine will eventually destroy it
No. Lexus is part of Toyota.

It leaks from the failed part.
Assuming you mean coolant (shouldn't run straight water), the coolant is pumped through the water jacket by means of the water pump. This is part of the cooling process for the engine. The knock sensor happens to be where the drain plug used to be.
There's a coolant temperature sensor located on the lower part of the water pump on the drivers side.
Quality Lexus parts may be purchased at a Lexus used auto part dealer. You may also find Lexus parts at local auto part stores in your area as well as the dealers.
It depends on what Toyota dealer. Since Lexus is part of Toyota, they probably will, but if you give your Lexus to a Lexus dealer, it will be less expensive.
well it depends where you live. The most efficient coolant is plain old water, and if you live in an area that rarely freezes for more than a day or two at a time then that's all you should put in - just water. If you live in an area where freezing could be a problem then put in a mixture of 2 parts water, one part antifreeze/coolant. Any kind will do, they are all the same. All "coolant" is is water with a little antifreeze in it.
NO, Lexus is Toyota's premium brand. Ford owns part interest in Mazda.
pressure test your coolant system, if it wont hold pressure you most likely have cracked some part of the engine internally, hence leaking coolant into the oil

you have a blown headgasket, or if it is has an automatic transmission, it is also possible that you may have transmission fluid in your radiator. this is caused by transmission fluid in part of your radiator leaked into your coolant
