Terranovation Posted March 12, 2016 Share Posted March 12, 2016 You know those three plastic things on the front of the bonnet, I'm not really sure what they do as they aren't really offering much ventilation for the radiator, but anyway, this is how you can remove them if you are interested, for painting or whatever. Open the hood and look on the inside where you will see where the other side of the plastic is. There is three nubs of plastic on this side with little fin structures. Use a flat head screwdriver or a fork to push these in and you'll feel it pop out, then remove. Very handy to remove them for painting instead of trying to do it while they are still on the hood. I even thought about cutting a larger slit down the middle of each one to get more air through them. Another idea I had was installing led strips into each of them but was unsure how to hide the wiring because when you open and close the hood the wiring might catch on stuff.

RF600 Posted March 13, 2016 Share Posted March 13, 2016 I'm not sure what their purpose is also. I do believe they do flow a little bit of air through them. Link to comment Share on other sites More sharing options...
Slartibartfast Posted March 13, 2016 Share Posted March 13, 2016 I popped the ones out of my '95 ages ago and yes, there is a tiny slit in each one. I enlarged the slit on mine slightly by cutting the baffle looking deal off the back. Even then, I suspect more air gets into the engine bay through the hood gaps.

Terranovation Posted March 14, 2016 Author Share Posted March 14, 2016 I think the idea was the smaller the gap, the air is compressed into a fine stream of air for better cooling of the top radiator tank. Think of a garden spray nozzle, the finer the spray, the water droplets are either a blast of water or a fine mist. Link to comment Share on other sites More sharing options...
Kyle_Cope1 Posted April 29, 2016 Share Posted April 29, 2016 They are pretty useless. I wanna get a matching green good off of a hardbody so I can get ride of those things. They most likely create more drag on the truck(which is not needed). Link to comment Share on other sites More sharing options...

adamzan Posted April 30, 2016 Share Posted April 30, 2016 And unless you are some kind of engineer, or have access to a wind tunnel, you can't say it makes any difference for sure. Link to comment Share on other sites More sharing options...
RF600 Posted April 30, 2016 Share Posted April 30, 2016 I'm not an engineer nor do I have access to a wind tunnel. The vents are there for a reason. Maybe to disrupt the air flow to allow it to go over the vehicle better? I didn't design the vehicle. Common sense would dictate that a large flat area is bad for air flow to start with.

Terranovation Posted April 30, 2016 Author Share Posted April 30, 2016 They are there for you reason, I agree. I believe they are to distribute the wind to create less drag on the front nose, kind of directing the air into the nose, rather than straight against a flat panel.

Slartibartfast Posted May 2, 2016 Share Posted May 2, 2016 (edited) You guys are overthinking the holy hell outta this one. Those vents are there for the same reason Mustangs have fake brake scoops, H3 Hummers have fake hood louvers, and my friend's FWD commuter car came with a spoiler. Somebody on the design team thought it looked cool. Seriously, you think the WD21 was designed in a wind tunnel?

KovemaN Posted May 2, 2016 Share Posted May 2, 2016 (edited) Seriously, you think the WD21 was designed in a wind tunnel? If it was, that has to be the worst wind tunnel in history Edited May 2, 2016 by KovemaN 1 Link to comment Share on other sites More sharing options...
