 Posted: Fri Feb 01, 2013 3:04 pm Post subject: Radiator cooling duct |
 |
|
I'm converting my 82 air cooled to water cooled. I ordered the side duct for the radiator and can't figure out where or how they mount. My van has had every hole pre drilled for everything to add a cooling system but nothing for these ducts. I tried to search for a picture but couldn't find anything. these are the ducts i'm talking about.

Thanks, Andrew |

Just wanted to revive this thread. I got two radiator ducts from GW, and can't figure out how to install them. The bentley diagram looks different than the picture on the GW website here
http://www.gowesty.com/ec_view_details.php?id=23501&category_id=18829&category_parent_id=
I dont see any ways to attach the sides to the bottom duct with screws as pictured. nor do i see any way for the screws to go in the side.

I eventually figured everything out. Several of the connectors that connect the baffles to the body were missing. One thing that helped to know is that they kind of have to be bent along the existing creases, more or less at right angles.

Anyone notice a difference if these are not there?

I have no ducts and the engine runs plenty cool. When I installed AC, I added an aluminum panel across the bottom to fill the gap between the nose and the condensor and radiator. The factory had a peice of foam that absorbed water and started to rust the valance out. I am diesel powered with aftermarket AC.

I removed mine while doing some work.. Drove it for several months that way.. then reinstalled.
I noticed slightly less wind noise, at speed, with ducts installed.
No noticeable impact on cooling.. but worth noting, I don't drive too much in hotter climates.
Worth noting, too.. I had a weird intermittent fluttering noise coming from the front end for several years. Could not track it down to save my life.
When I removed the ducting.. it magically went away.. Since I reinstalled, it has not been back.
Figured, maybe, a loose duct flap was vibrating from airflow in certain wind speed ranges.

You can remake them in aluminum sheet or other material. Yes they can be installed with the radiator in place, at least on my '87 I can. |
However probably easier with the RAD. out.
I guess the basic idea is to make a baffle which funnels the air 'into' the rad..

I would believe going down the road there is plenty of air flow across the radiator with our without the duct pieces. Where it might make a difference is sitting still when the radiator fan is running. You might be pulling air from around the sides of the radiator, which would be hotter than ambient in front of the grill. Not enough to worry about.

@ epowell
the ones from VC are plastic not cardboard.. you can easily install them with the rad. on |

OK.... there is a huge load of info on these in other threads, and templates to make them... so I will give it a shot out of 0.6mm aluminum painted black.
Can anyone tell me if it is any easier to install them with the RAD. out, or maybe actually better to install with the RAD. in.... probably yes, since the baffles need to fit TO the rad..

Just now re-installed the RAD, and looking at the tiny crack of a space I should install those baffles... seems REALLY tight!
Wouldn't it be easier to install them with the RAD. out? ...or are the baffles attached or screwed to the RAD. itself?
It was dark outside, I will inspect again in the morning, maybe I will see it differently in the light?

Yeah I was thinking that in the light, it might seem easy from the front. But how is it bolted on? ... and to what?

Got busy today attempting to make those baffles....
First found some templates on-line and drew them out onto cardboard > then inserted into the van and fine tuned the shape. Then cut this shape out of 0.6mm aluminum.
Out to the van again and spent quite some time tweeking this to fit >> the big AHA moment came when I realized that the one edge of the baffle must tuck into the lip on the edge of the rad., this way the thing gets held tight when one screw is attached to the other side.
