Yes, but the car is 42 years old now.

Have you tried any of the "water wetter" products? Redline makes one as does Royal Purple (Purple Ice). These work by improving the contact of the water/coolant with the surfaces it interacts with. If you have corrosion in your engine block or radiator, the water to metal contact will be less than ideal. These water wetters increase the contact and thus increase the heat transfer. Thus the engine will transfer heat better to the coolant and the coolant will transfer heat better to the radiator.  

I have used the Redline product in several vehicles and it works. These will cause no damage and for less than $10 may help quite a bit.

It wasn’t like this in 1964 when it was new, so it should not be like this now.  How’s your fan shroud?

Subject: IML: Cooling Issues

 

Here in Las Vegas, the summer temperatures routinely reach 115 degrees.  When I drive my 64 convertible, I usually don't have any problems.  The temp gauge will go to 3/4 and pretty much stay there.  This is wtithout the AC on.

However, if I do some real slow driving, like bumper to bumper strip cruising or in a parade (which I do a few times a year), it pegs out and the car starts pinging until I can get some air flow going.  I don't have the AC on in this condition, obviously.

Everything has been rebuilt under the hood, including the engine, the water pump and radiator.  I just redid the AC compressor and attendant parts and at freeway speeds there is no issue.

Around town is what concerns me.  I want to install an aux. electric fan(s).  The smallest I can find is 10 inches with a housing dimension of 11.5 X 12 X 2.  The center nose support brace prohibits anything larger and I was thinking of putting two 1250 cfm fans on.  But, it will be tight in the space allowed on the front of the AC condenser (22" wide).

Each fan will draw about 5 amps.  I'm told the standard alternator is only putting out around 60 amps and the ten more would likely create a problem.  NAPA suggested a higher power alternator and a change in the voltage regulator.

I was unable to find anything related to my issue on the website.  Anyone with suggestions to help me?

Thanks
