I am considering replacing the 4-blade fan on my '57 ZB with a 6-blade replacement from an MGA. Our summers here in Houston are really hot and I thought the extra blades would help lower engine temperture. Has anyone done this and are their any problems in making the change? http://www.mgexp.com/phorum/read.php?27,1627897,1627897#msg-1627897 Wed, 22 May 2013 03:11:47 -0500 Phorum 5.2.15a http://www.mgexp.com/phorum/read.php?27,1627897,1634835#msg-1634835 http://www.mgexp.com/phorum/read.php?27,1627897,1634835#msg-1634835
Thes car wasn't hot, only the guage was.... I simply took the gauge out, ran it up to the 190-195 range on my lab thermometer, and with the needlenose pliers, re-set the guage needle to the upper edge of the middle temp block. Now when it runs in the summer in Texas, it rarely gets over 190 and I know we are a long way from overheating anything.

The water won't boil even at 212 with pressure and that's not very warm for modern lubricants, so don't worry about it. Just tweek your gauge needle a bit and quit worrying. When mine reads hot now, it probably will be hot, but so far it doesn't get there.

Bending up some stainless or mild steel sheet into a steep angled blade and then rivetting these onto the fan body would work well and look good if done carefully. If it is 'too noisy' just reduce each trailing edge a bit at a time and ensure that balance is maintained. Supplement this with a pusher electric fan set to cut-in at the appropriate time and you should be right.]]> enigmas MG Magnette Forum Thu, 16 Dec 2010 06:30:53 -0600 http://www.mgexp.com/phorum/read.php?27,1627897,1628061#msg-1628061 http://www.mgexp.com/phorum/read.php?27,1627897,1628061#msg-1628061
And though it sounds silly, never assume that the fan has been installed the right way around unless you do it yourself (have had it happen once after an engine rebuild and luckily noticed before too long)

Phew, Texas summers in classic cars, geez I don't now know how I did it...those were the days!]]> EHarvin MG Magnette Forum Tue, 14 Dec 2010 12:19:23 -0600 http://www.mgexp.com/phorum/read.php?27,1627897,1628041#msg-1628041 http://www.mgexp.com/phorum/read.php?27,1627897,1628041#msg-1628041

What I can tell you from experience of having lived in Texas back in the 80's and 90's driving all manner of 30+ year old clunkers as daily drivers (not a Magnette back then though) is that the best thing I ever did for keeping the temps down was having the radiator recored. A bit off topic and a little more cash than a fan blade to be sure, but well worth it in those conditions.]]> EHarvin MG Magnette Forum Tue, 14 Dec 2010 09:02:56 -0600 http://www.mgexp.com/phorum/read.php?27,1627897,1627897#msg-1627897 http://www.mgexp.com/phorum/read.php?27,1627897,1627897#msg-1627897 archangel MG Magnette Forum Tue, 14 Dec 2010 07:35:22 -0600
