its so easy i had to replace mine on the side of the road in downtown tampa on my coupe
also after you replace the hose if you see the car overheating it means there is an airbubble in the cooling system and you need to bleed it out.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
