I'm not entirely sure what you mean, but I'll give it a shot. The cheetah has tear-like black markings under its eyes that help to keep the sun out of its eyes and cool it down a bit. Does this answer your question?
They need more heat for there bodies if they were smaller they wouldn't be able to make as much heat
Mammals have higher metabolic rates than reptiles, which means they generate more heat internally. This excess heat needs to be released to maintain a stable internal temperature, so mammals lose more heat energy through mechanisms like sweating, panting, and shivering. Reptiles have lower metabolic rates and can rely on external sources of heat, like the sun, to regulate their body temperature.

NO. Mammals are endothermic, and give off heat. endothermic creatures are also known commonly as 'warmblooded'.

The way all other mammals do.

Most reptiles use heat sensors to detect prey. But, most mammals have good eyesight because they don't have heat sensors. They use only their eyes.
Mammals are covered in hair. They are endothermic ( produce their own body heat) They produce milk to nurse their young.
They are mammals, as are all bats, and most mammals have body fur for heat control and skin-protection.
Mammals will shiver or posses what is called 'brown fat' that continuously produces heat.
Mammals belong to the phylum Chordata and are endothermic, meaning they can produce and regulate their own body heat.
