[TR] Uprated water pump question

[THOMAS FANSHER]

A buddy put the 6 fan on his car and to do so had the fan extension milled 
3/16 " from both ends. So the extension ended up 3/8" shorter and had to do 
no other modifications and it does great in the Florida summer heat.  I just 
removed my fan and extension and put the Ken Glanders harmonic balancer on 
and installed an electric puller fan. Also did the alternator upgrade. I had 
an electric pusher fan for years on the 3 and it worked great. Yes, recoring 
is important and leaving out the hole, they make heavy duty cores ( for 
trucks - talk to your radiator guy). While the radiator is out, you can 
install a bolt through the bottom of the radiator mount so that 
reinstallation is much easier.  You just set the radiator down on the bolt 
and install the nut from the top instead of trying to thread the bolt 
through. That was a help from the list probably 15 years ago. I did not 
install the 6 bladed water pump.
just my two cents worth.
