HI everyone, sorry for my ignorance, but what is the exact name for that
thing between the radiator and the actual motor , its black and has stripes
going sidways, the reason im asking is cause my sportage makes weird
crackling noises when i start the engine but after 5 min of driving it calms
down to normal. Thanks for the input.

Ps, here is a pic of a kia sporta motor
