HAS ANYONE USED A CHAMPION ALUMINUM RADIATOR IN A 1941 MERCURY. The Original Mercury Radiator has the Cast Iron lower outlet tubes, which form a rectangular connection to the bottom sh*ll of the radiator. The connection is 2 3/8" wide outer dimension. The Cast Iron lower Hose tubes are 8 1/4" tall and attach to rubber hoses that are on the same plane as the water pump outlets. The Cast Iron tubes are 20 1/2" Center to Center. The connections are the same 1 3/4" exterior dimension. The Champion Aluminum Radiator is supposedly 40% more efficient at dissipating heat. The Aluminum Radiator outlets are 16 1/4" Center to Center. Using 1941 Ford lower radiator hoses on the aluminum radiator , the hoses pinch on the torsion bar and they do not clear the Fan Blade. See picture. Has anyone found a firm that modifies or fabricates a 1941 Mercury Aluminum Radiator, or knows of a way to modify what I have? Thank you

The copper core radiators transfer heat better than the aluminum radiators. If your core is plugged or otherwise bad, I would have it re-cored with a copper tube radiator with the correct number and configuration of fins and tubes. The main advantage that aluminum radiator cores have over copper cores is price, any other comparison will find the aluminum falling behind. Tom

my vote is to have the original radiator redone will save you hours of frustration, trying to make the aluminum radiator fit. looks like it will be real hard to make the bottom pipes, out of aluminum pipe. and tig weld it all together just find a good radiator shop my 2 cents 37Ragtopman

Thank You to Tomo, I had the original radiator recored and a I had a second radiator from a I car I bought in Wisconsin that was a field car. The Driver's side lower tube was in much better shape than my radiator, even though the rest of it was shot. Champion Cooling Systems has a Cadcam Drawing of a 1941 Merc radiator, but have not decided to produce it yet. Maybe if enough embers show interest they might consider it. As original radiators get scare for rebuilding an alternate source might be good. Not sure how many would need to be a production run. The cost would be between 1/4 to 1/3 the Price of a recore. This certainly would not be an option for High Quality Restoration.

"Wondering ir a Ford radiator the same or are their differences?? You might ask this question on the Ford Barn................ Paul in CT" The 41 Mercury radiator is a one year radiator that was used only on the Mercury. See photos posted by the OP. I don't know how many radiators would be the minimum for making a reproduction, but there are fewer 41 Mercurys being restored than any other year Mercury. If you think that there might be enough interest, contact Champion to see what kind of commitment they would need to start production on the radiator. Then go though your roster and send a letter or E-mail to all of the 41 Mercury owners that you can find. Ask them if they would commit to buying an aluminum radiator from Champion. Once you have this information, you can contact Champion to see if they are willing to go into production using the commitments that you have. Tom This message was edited by TomO on 7-15-21 @ 7:13 AM

Attached is a better description of how a 41 Merc radiator is different than a Ford radiator The Mercury Radiator has Cast Iron Tubes which are brazed to the Lower Tank. The ports on the lower tank are 2" wide and 15/16" tall. The rectangles are 16 1/2" Center to Center. The Cast Iron Tubes brazed to the bottom tank provide an 8 1/2" rise so the outlet tubes are Parallell to the water pump inlets. The 41 Merc lower tubes also provide a 20 Inch Center to Center Separation . This allows the Merc hoses to clear the Torsion Bar and not touch the fan blade. A Gates Hose Part Number 21284 has a 1 3/4" inside diameter which has a section that can be cut out to Profile a 1941 Merc lower Radiator Hose. I purchsed that from CAR QUEST Several years ago . Car Quest was purchased by Advance Auto Parts. I bought replacements today, 7/17/2021 from AUTO ZONE (special ordered) which cross to the Gates Hose. It is a DAYCO Hose Part Number e711461231 L I had two 50 year oldd hoses to use for patterns. One was a Bowes Seal Fast Part Number BH-51, the Other was a Gates Vulco Part Number CH-84. The Gates Vulco Hose was 3/16" longer than the Bowes Seal Fast Hose. Regarding New Hoses The Car Quest Hose seemed more pliable than the Auto Zone Hose. The lower hoses are a tight fit. One of the attached pictures shows the hose profile set up for cutting by white Duck Tape.
