VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

My "fan" experience with an altered '47. (1) Tried an electric fan only because my belt-driven fan (see below) makes considerable noise at higher RPM. It was sized to fit the radiator width but it did not move enough air in city driving so I changed back. (2) Regarding the belt-driven radiator fan that came on the car, it is a replacement composed of six fiberglass blades, apparently intended to pull more air in than the stock fan. (3) the car also came with a round rubber fan "shroud" with metal edging that attaches to the inside of the radiator and surrounds the fan blades .... its function intended to enable the fan to better pull air thru the radiator .... I did not install it. The fact that such shrouds were or are installed on cars suggests to me that excessive distance between the fan blades and inside radiator face may contribute to overheating in city traffic i.e. when at stand-still air is simply "churded" around the engine compartment instead of being driven out but the fan pulling air in.

Hello Hot41,

Here's my less-than-2 cents:
1. An engine with the ignition too far retarded may overheat.
2. Since it's an easy task, try eliminating the thermostats temporarily. While you have them out, submerge them in close-to boiling water to determine if they're actually opening.

My '40 has 170 degree stats in it. On a hot day (85-90), even idling a while, the verified bourdon-tube type temp gauge reads 170-180 degrees. The instrument panel gauge readings are all over the map. I believe it's either the original sending unit or a NOS replacement.

overheating problem
did you check for bubbles in the coolant, maybe there is a headgasket seepage ?
you can do this at idle on level ground , fill up the radiator so it is full
and use a thermometer in the coolant and compare to what the dash gauge reads,
hope this helps, 37Ragtopman

That is a BEAUTIFUL '41!!!

First I would make sure that it is really overheating. My 40 appeared to be overheating for years, but it was the poor quality, reproduction sending units giving a false indication. Mine was never overheating! If it isn't boiling, then you might get an infrared temperature gun or (and this is crude) install a cooking thermometer in the radiator cap-either will tell you if it is really overheating.

I would also make sure that, if you are running thermostats, they have not been pushed up into the upper radiator hoses. There are several posts about that on this forum.

I did install the more modern water pumps with the curved impeller vanes and an electric fan, but I am not sure how much good they do.

There are a lot of people on this forum with more knowledge and experience than I have, so you should get lots of good responses on this subject.

Here's a pic of my 1941 Super Deluxe convertible on a hot summer's day (85°F) with stop and go driving. Clearly she doesn't like it. Any suggestions of what to do to keep her cooler? There's a big aluminum radiator (supposedly new from the previous owner) and I just had water pumps replaced. Wondering if an electric fan might be the way to go here? I'm an early Ford newbie so would appreciate any wisdom others have on the subject.
