No , the engine should be cool before adding any fluids to the engine cooling system
When the a/c is turned on in any auto it makes the engine work harder, this will tend to heat the engine more. Make sure that your cooling system in the car is running properly, and is full of cooling fluids.
cryogenic fluids are - degree temperature means below -4degree Celsius up to -184degree Celsius but in ordinary cooling fluid doesn't having that much of lower temperature

Does it say Engine Prot? means that you might be low on fluids such as coolant and the longer you run with it it, it will start to slow down the engine until u stall out....happen to my cat c7 in my freightliner. and it turns out i blew my cooling system.

There is no way to really be sure how a used luxury car will run. It depends on what year it is, if the engine or transmission have been rebuilt, if the vehicle has been well taken care of and fluids changed, what size the engine is, etc. If they were well taken care of, even some 20 year old used luxury cars are dependable.
You fill it threw the dipstick tube.
Whoever owns the vehicle should have it taken to a mechanic for inspection. It sounds like something's wrong with the gears, not the fluids. If it's the gears you should probably have the transmission rebuilt. If it's the fluids have that refilled.
If you are driving and water is sucked up in your engine it will ruin your engine. but if the car is sitting in water not running dont even try to start it. Drain all fluids out of the car and replace them all with new fluids.
chec all fluids my have engine light reseted
