When i touch the hood after a drive, middle of the hood is cool, sides and corners are hot, especially around headlamp and top of fenders. That makes me think hot air circulated in the engine bay finds an air flow through sides, starting near headlamps and go through a closed line out of the engine bay, and gets out from the corners of the black plastic (they are flexible and cut. they are olso relatively hotter after a drive) next to the windshield.
But the reason center of the hood is colder might be because of the woven spongy heat shield kind of thing under the hood.
I really dont want to get a vented hood because they look too aggressive. So considering fender garnish vents these days again but want to make sure if they will be effective enough.
I know fender garnish vents efficiency had been discussed many times before, and that there is no low pressure area there so it is not so effective. But never read anything related to that "hot line".
It might be close to a vented hood in terms of efficiency if there really is an air flow at the sides and can be directed out of these fender garnishes with a small duct.
Anyone has an idea about that?
