I am assuming that by coke you mean the beverage rather than the fuel or drug, although putting any of them in a vehicles fuel tank will damage or destroy the engine, depending on how long it is driven. It is rumored that Windex will cause the engine to explode, but that cannot occur (Windex is mostly water). Either way you should only do it if you really don't like the owner of the vehicle and don't mind facing prison.
Windex has ammonia included in its ingredients. When bleach and ammonia mix they form "chlorine gas." This gas is very dangerous and can be fatal.
