proper vent settings for cold or hot...1990 GL 1500

Post by DougR » Mon Jul 03, 2017 6:39 pm



Group

I have a 1990 GL 1500. In front of each knee are two vents and one lever within one of the vents.

If I were trying to obtain maximum heating what would the vent config look like?

I think it is top vent on each side is closed

Bottom Vent is open with the lever in the up position

Is that correct?

Thanks

The top vent is fresh air only. The bottom vent is fresh air, either warm or cold depending on the lever setting. I believe (if memory serves) that the lever down gives you warm air...but honestly, such a tiny amount of air comes out of either of those vents, I never notice a difference.

I have done some modifications on the vents to get only hot air when open.

Closed the upper fresh air ducts with a piece of foam, removed the valves in the lower vents, installed a piece of 80-mesh in the fan outlets to restrict the %60 of the air flow. So now, the lever in the lower vent does not have any function, but upper vents can give hot air also.

My test results in last winter are as follows;
0-5*C (32-40*F) In the city traffic it works very well (temp gauge 1/2), but not satisfactory in the suburban areas (temp gauge 1/4)

Over 5*C (40*F) it is satisfactory in and out of the city traffic (temp gauge 1/4 and over)

Over 15*C (60*F) removed the meshes

To get a better result, I think, we should also restrict the radiator air flow as in the old day cars.

I wondered about fitting a rubber connector over the hot air vent adding some "hose" and sticking it up my pant leg???

With my solution you will not need such a thing. Actually, the upper part of the leg (I think it is called thigh) can not receive enough warm air due to the position of the upper vents and the air channels on them can not be adjusted over 90 degrees, so they need some modification that I haven't done yet.

I have found on my SE that the lever on the lower vent does not help get any warm air on me. I guess the air is marginally warmer but not enough to make any difference in how it feels. However, the knob on the right side of dash that opens up the flap down by my feet does help. I can feel a difference in my lower legs when it is open on cooler days.

As I have said, you need to block the fan outlets, and direct more air to the vents.

The hot air coming from the flaps are heated by exhaust manifolds, as you know. I have also thought to use that heat (as on the VW beetles), but then given up thinking it might damage the plastics.

Thanks for all your comments. I forgot to mention the knob on the top. but first, I think I understand the bottom and top vents now.

Top would only be for cool

Bottom for heat or cool. When I move the lever in the lower vents, I see black plastic or the engine...I presume looking at the engine is warm mode!

Now to the knob on the top. What does Closed and Open mean? What is closing and opening...again trying to find out if Closed or Open provides more heat...lol

I'm going to write me a check list on this!

Turning that knob to the right opens up the flap down by your feet. It lets warm air from the exhaust pipes flow out and help warm your feet and lower legs. Turn the knob while looking down by the exhaust and you will see them moving.

I'm sure closing off the fan outlets would cause much more heat to get out those vents. We don't have a lot of cold weather where I am so that is not needed. Those foot warmers do help out when I am off on a trip in the mountains though.

Okay...if I paste this on my windshield, I should be able to ride with serious brain fade. What do you think of my checklist attached

I see, I have been to Alabama, Fort Rucker near Enterprise. I know how hot the weather is there.

Yep, it can get pretty hot here, this time of year especially. It is 95° outside right now as I type this. Often we have the high humidity to match the temperature too, so that makes for a very sweltering day. Days like that is when you try to stay where there is air conditioning!

Can always get warmer with electric gloves, coat, pants...but staying cool is the problem...I think I will leave the wing in cool mode.

Planning a trip to Yosemite in Aug mornings should be perfect.

I'm guessing for helicopter training. Ft. Rucker is all about the helicopters.

I hear ya. 95f in the shade here right now with a heat index of 111. Typical summer day for south Alabama.

Right, once upon a time I was there at the test pilot course.

With the lever down on the small vent warm air is directed to your legs, lever up is cool air. If you look really closely you will see a little H and C on the vent it's self. (at least on my 97) I like to think of it as hell is down and hell can be a little warm, or so I am told :D
I purchased a set of plastic covers for the fan outlets a few years back, they were made specifically for the 1500 and had a little spring loaded knob to hold them in place so they were very easy to install and remove. They did help a little bit but still not great heat. I also got some plastic parts to help direct the toe warmer heat closer to feet but they broke on the second use.
