In the old days of copper and brass radiators this was true. More rows meant more surface area in contact with the fin and consequently a higher heat rejection. So a 3 row was better than a two row and so on. When aluminum radiators came around the rules changed. Cooling engineers concluded that by lowering the fin height you could stack more layers of tubes. In addition, using wider tubes ...
Aug 16, 2012 switched to a 3-row aluminum rad which also cooled ok = did not appear any better than the 2-row aluminum. i dont think the tubing width is as wide (3-row)in surface area as the (2-row 1tubes). if your looking for the best cooling, a 2-row with 1.25 tubes has the greatest surface area and offers the best cooling and airflow thru the unit...
May 17, 2021 With most aluminum radiators, you will get wider, more efficiently shaped tubes that help cool coolant faster. More Rows. Aftermarket aluminum radiators are often offered in multi-row options. You may have heard the terms 2 row radiator or 3 row radiator used in the industry. This simply refers to the amount of rows in the core of your radiator.

May 04, 2020 Aluminum radiators have helped to solve these problems. Because aluminum is stronger, the tubes can be wider. This means more contact area without significantly increasing the
May 30, 2007 He did recommend an aluminum two row high efficiency radiator that is supposed to cool just as good without the thickness of a three row because it is aluminum. The choices for the
Oct 02, 2012 The usual advantage of using a three row vs a two row core is you get additional capacity for coolant. If the tubes in the two row are large, the capacity gain going to a three row may
Nov 17, 2011 Im in need of a new radiator for the 68 and have pretty much settled on using an Ebay aluminum radiator. While the bigger is better mentality says go with a 4 row,Id like some input on
Mar 26, 2015 In the old days of copper and brass radiators this was true. More rows meant more surface area in contact with the fin and consequently a higher heat rejection. So a 3 row was better
Aug 03, 2020 If the 3 row has more coolant than the 2 row it will flow slower and have more time to cool. Fin count also plays a part. The more fin contact per row the better, up to a point. You dont
Oct 13, 2006 A 2 row aluminum radiator with a 2 2 row core will cool better than a copper/brass radiator of 2.5 with 4 rows. Air restriction through a core is increased with thickness. Aluminum
May 30, 2007 He did recommend an aluminum two row high efficiency radiator that is supposed to cool just as good without the thickness of a three row because it is aluminum. The choices for the aluminum were all aluminum ($500ish) or aluminum with plastic ($160ish). ... More of an opinion than a known fact, but the two row Modine aluminum
Jul 27, 2020 A 2-row radiator with 1 in. tubes will have more tube-to-fin contact than a 3-row radiator with 5/8 in. tubes. The radiators will be about the same thickness. The 2-row radiator will be less restrictive to airflow. In this example, the 2-row radiator has more cooling capacity than the 3-row.
Aug 03, 2020 If the 3 row has more coolant than the 2 row it will flow slower and have more time to cool. Fin count also plays a part. The more fin contact per row the better, up to a point. You dont
A typical 4 row copper radiator uses 7/16 tubes while the aluminum radiators use two rows 1 tubes. Then the copper radiator uses 1/2 tall fin while the aluminum radiator uses 3/8 fin. The shorter fin increases the number of tube layers in a given stack up. For example a 18.5 tall radiator
Sep 06, 2018 In this case a three-row aluminum radiator would only have a total of 1.86 inches of tube-to-fin contact surface, which is less than the two-row core with 1.0-inch tubes. Some ads for these three-row aluminum radiators will indicate several features of the radiator
Apr 29, 2020 Which is better 2 row or 3 row radiator? More rows meant more surface area in contact with the fin and consequently a higher heat rejection. So a 3 row was better than a two row and so on. When aluminum radiators
Feb 23, 2020 A two row aluminum radiator (with larger 1 or better yet 1.25 tubes and more cooling fins) will cool more efficiently than a 3 or 4 row copper/brass radiator. Most of the older design copper/brass radiators have smaller diameter ( 3
Nov 19, 2019 2 Row - A thicker version of the original with 20-40% more cooling capacity. These normall fit stock and are a great no nonsense replacement. 3 Row - a thicker version of the radiator with thicker side or top and bottom tanks providing up to 100% additional capacity. 4 Row
He generally tells customers that a high efficiency (tubes on 7/16 or closer centers) copper four row will cool the same as an aluminum core with two rows of 1 tubes. If more cooling is required from the radiator than either of these designs will provide, than an aluminum core with two rows
Jan 16, 2011 All aluminum can be a catch phrase. The majority components can be aluminum, but the welding may not be. There is a lot of Chinese junk coming over here, A 1 inch two row aluminum radiator will cool with the best of them. A well constructed 3 or 4 row brass will do the same. Check out American Radiators
Mar 29, 2010 Registered. Joined Nov 9, 2007. . 643 Posts. #3 Mar 22, 2010. I prefer the 2 row aluminum, the tubes are typically bigger and the aluminum radiators transfer the heat better. I went
Mar 18, 2006 If I ever have the need to go with more than 3, I think Id go with a 2 row alum. at that point. As you probably know alum. rads can use larger dia. tubes and therefore cool better than an
Jul 25, 2020 I already ordered the 433168 radiator and may try it anyway instead of returning. From what I read, it should be better than my copper, but probably also at its limit. So, I was thinking of
Feb 24, 2007 Generically speaking, aluminum dissapates heat faster than copper. Airflow thru the radiator and surface area of the tubes makes a great deal of difference. Consequently a three row
Jan 28, 2017 FYI keep in mind 3-row and 4-row copper brass radiators and 3-row and 4-row aluminum radiators are not the same thing. You are WAY better off with a copper/brass 4-row than

Jan 27, 2010 The factory radiator has an aluminum core and aluminum is best at conducting heat out of the coolant. But if you have a choice between 1, 2, or 3 row radiator, a 1 row is more efficient
Jun 27, 2018 Brazing radiators is quite a bit more difficult than say, brazing two copper tubes together for a water heater install in your house, but the process is similar. There are two main braze joints on
Nov 19, 2019 Generally a 1 row radiator will measure 1 inch to 1-1/4 thick. (Stock Radiators) Generally 2 rows will measure 1-1/2 to 2 inches thick. (Tow Package Upgrades) When comparing
Nov 10, 2011 Aluminum radiators are better due to low weight and low cost. Co-efficient of Heat exchange for the aluminum material is higher than the stock so there is better cooling of the engine.
In short, an aluminum radiator is likely the better choice for a high-performance engine, and for a custom rod (where the radiator may be more exposed), while a copper/brass radiator will remain the
Mar 19, 2010 Hi everybody. A couple of questions: 1. What is the difference between a two row and three row aluminum radiator? Which is better? 2. Is a aluminum cross flow radiator better than a
Jul 22, 2014 An aluminum rad typically uses two rows of 1 tubes, thus more surface area to disipate heat better than your current 3 row radiator. Several studys have been done and the general
A two row aluminum radiator (with larger 1 or better yet 1.25 tubes and more cooling fins) will cool more efficiently than a 3 or 4 row copper/brass radiator. Most of the older design copper/brass
