the temps were in the low 90's as soon as i got off the freeway and sat at a light in maybe a minute it hit 210 and i had to shut it off as it reached 220+ and climbing fast. Did not take more than a two minutes idling for that to happen so i am thinking maybe the fan is too close to the radiator or would an electric fan be best for those occasions when i get to very hot climates.

Stu, what size radiator 22 or 26 inch? And I would use a 7 blade fan with clutch. As for your temp rising when at idle in hot weather, you are not getting enough air flow and an electric fan set up with a manual switch should cure that issue. I have a few factory fans avaialable let me know what you plan on doing as I can more than likely hook you up with the needed parts.

The 69 manual calls for radiator to front of fan gap to be from 3/4" to 1-1/4" The closer you can get your fan to radiator the more air you will draw in through your radiator which will help your overheating problems sitting in traffic.

Stu, an electric fan would be the easiest way to deal with the problem. If all is good at speed then the electric fan is the answer. I have my original 26" radiator that is sitting on the shelf that is yours to use if you want. If may be all you need to take care of your cooling issue at idle, if it works then a bigger radiator is in order. Let me know if you want to give it a try and I will drop it off.

You know Herb at one time i was going to go with the 26 inch but if my opening was only 22 then i figured the extra area would not be used efficently?? So i had the originl just cleaned out and rebuilt maybe 5 years ago by the gur in Pacifica.

I am leaning towards a front mount puller electric fan on a switch that i can control from inside the car.

Ok so you do want the fan as close to the radiator as possible then??

As close to the rad as you safely can w no shroud but you are running one as you should so that changes the requirement & w them you want the blades ~2/3 of the way into the rear side of the shroud. MP thermal clutch fan w a fixed 7 blade is the best but just tossing on a fixed 7 blade one from your stash (w no clutch) will ans the Q if it is strickly an inadequate fan prob (my that's it) WO you having to purchase the good thermal clutch fan which just engages/disengages when it gets hot but is not magical for upping the CFM but only saves HP by it's being disengaged until the heat rises to a certain level

My dad's Super Bee has a 22' radiator in it with a 7-Blade fan and a fan clutch and I never recall the motor ever getting hot. It has been driven to LA and to Sacramento a few times and has always stayed cool. I agree with Herb, 7-blade fan with a fan clutch, or an electric fan with a switch should work just fine.

Since 99% of the time the engine runs perfectly cool, i think i will look into the electric fan option. I always wondered though does the phyical mass of the fan in front of the radiator stop some air flow when it's not being used though?

That is what I would wonder about, never know until you try it.

But if I were you, I would reinstall a 7 blade fan and clutch. I'm almost sure that would solve your problem without any load on your electrical system and won't block any air flow. My

A good thermal clutch with a 7 blade fan complemented by all the incoming air being forced through the rad by adding air dams and blocking the charge from going around would be my first attempt...
