If this thermostat only opens when the temp is too high, then it will barely be putting any oil through the cooler anyway.olor me confused... Some production airplanes including Warriors and Cherokees use a bolt-on winterization plate to completely block off the frontal area of the oil cooler for winter operations. In fact the 0-320 equipped 1974 Piper Warrior's oil cooler is mounted exactly the same way my plans mounted cooler is and it has a permanently mounted back plate installed! The baffle mounted oil cooler supporting my 0-320 would barely attain degrees in the hottest of summer weather. Through trial and error experimentation, I eventually blocked off the entire back side of the oil cooler with a plate. This finally brought the temp up to 180-185 degrees. Even so, when winter arrived, the oil temp barely rose to 130 degrees so I blocked off the frontal area of the cooler like the aforementioned production planes. Then when a brief winter temperature inversion occurred around here, I had to remove it to keep from generating too hot oil temperatures. This is precisely why I brought the oil cooler vent/shutter from Van's. http://tinyurl.com/9xh9k Adjustable from the cockpit, this device should put an end to constant tweaking of the oil cooler to compensate for seasonal (or daily) weather changes.

Jeff, It was explained to me that there is a small flow of oil thru the cooler even when the vernatherm is closed. This is to prevent the oil in the cooler from congealing which would not allow the oil to flow thru the cooler when the vernatherm does open. Partially closing off the cooler helps the non-congealing flow to do its job and subsequently helps keep the oil temp up when there is a flow thru the cooler.

He replied off list so I'll remove his identity. Here goes: There is always oil pressure in both the return line from the cooler and inlet to the cooler line weather the oil is cold or hot. There is only full flow through the cooler when the oil is hot. When the oil is cold the oil is ported is such a way that there is the same oil pressure going down the return line as what is going down the in line to the cooler. Thus no flow. When the vernatherm expands it changes the routing so that all the oil goes through the cooler and then back to the engine instead of down both lines. When the oil is cold there is actually a very small flow through the cooler even though the vernatherm is open. This is done by design, they do that so that when it is very cold the oil won't congeal in the cooler because if there was no flow, the stagnant oil would "freeze" in the cooler effectively blocking the cooler and preventing its use once the vernatherm called for cooling. This is why when it is cold out and we can't get any real oil temp, blocking the airflow over the cooler will help run the oil a bit warmer then without the block installed because we blocked the cooling air attacking the non congealing flow through the cooler. Not trying to start an argument just trying to set you straight. No argument here. Thanks for the reply.

It's in parallel with the cooler, so when it's open the oil goes whichever direction is easiest. When it's closed (hot oil) it forces the oil through the cooler. So, oil is always able to go to the cooler and some always does, hence the reason for blocking the air to the cooler.

If you can verify that the date/time is correct then see if there is a way to set your approximate position. There should be a screen that shows the positions of the GPS satellites. If you can compare yours with a GPS receiver that is working properly you can see how bad the almanac is. Have it on in an area with a good view of the sky and leave it on It could take 20 minutes or more initially. Exactly what model is it.

This subject always comes up in cold weather, and several of our listers really do know how it works. Todays posts from Jeff Dowling and Dave Bristol seem to explain the operation of the v/t properly and concisely. I would like to add a bit of information if I may. I don't remember the RV type of the original posters question, but if it was an RV-4 ...... What else can I say. Every RV-4 wants to run at ~ 120 -130 deg. in the winter. On a miserable, hot summer day, we are lucky to see 195-200 deg. The very tight cowling on the -4 is overkill to the cooler, and the explanation about the bypassing of the oil seems to explain and confirm why the --4's oil temp is so low. I have had several RV-4's and have seen and performed several experiments. My current -4 has its cooler mounted to the rear baffle, and has a controllable flap on the rear(exhaust side) of the cooler. This has never, never worked well. In fact, it doesn't work at all. Because at normal flying speed, the air pressure entering the intake side of the cooler is so strong, it pushes the flap open a millimeter or two. This is enough to over-cool the oil. HOWEVER, on both my -4's the solution that always works is to partially or completely cover over the intake side of the cooler. PS Thanks Jeff and Dave. - Louis I Willig 1640 Oakwood Dr. Penn Valley, PA 19072 610 668-4964 RV-4, N180PF 190HP IO-360, C/S prop ________________________________ Message 19 ____________________________________ Time: 07:54:01 PM PST US From: G McNutt Subject: Re: RV-List: To/From Avionics Question --> RV-List message posted by: G McNutt Hi Mike If you have your GPS set up for IFR with an external CDI and you put a waypoint on "hold" you will get a To/From indication on the CDI as you fly to or from (over) that waypoint.. One example would be holding at an intersection, you don't want the GPS to cycle to the next route waypoint so the intersection waypoint goes on "hold" and the To/From will work just the same as if you were using VOR and holding at a VOR station. It's in the operators manual and your GX-60 manual is a lot better than my SL-60 manual!
