(Sorry still learning - and I've never seen ANY car fitted with a pre-warming system)

The block heater fits into the block and is in contact with the coolant. There are several types of heaters. Electric stick on, magnetic, dipstick heaters, upper radiator hose etc. Some heat the oil and some the coolant. But neither gets hot enough to cook anything.
