'68 overheating problem
I have a 1968 Mustang convertible with a 289. It has factory air (Thermo King brand, though i never run with it on), and the original 3-speed automatic. I had the entire engine rebuilt about three years ago, and ive put on about 4-6,000 miles since then. Even before then though, the car has always run hot, and i wasn't sure why. On days where the outside temp. is above 90 degrees, the needle sometimes even reads higher than the little H symbol on the car's thermometer (i just leave the car at home when its that hot). Is there anyway i could get the car to run cooler, or to cool it down? I've thought of adding aftermarket fans for the radiator, or getting a cowl cover for the space between the radiator and the front fan because i don't feel that the radiator is getting enough cool air overall. Any advice helps, i'll be sure to check back on this post at least once a day. thanks!

do you have a fan shroud?
how far is it bired over?
how many blades is your fan?
is it fixed or on a clutch?
what is you thermostat rating?
do you have ac?
how many rows deep is your current radiator?
you likely need a $300.00 dollar 3 row high efficiency radiator or even bigger.

I don't have a fan shroud, it's the first thing on my list i'm going to try. The fan is a single blade, and it's fixed. I have AC but i never use it (and have possibly thought of just taking it out). I'll check into radiators and see what could fit for the car, i have a feeling that is probably the problem. Thanks for the replies guys! really appreciate it.

hi;
there is no such thing as a single blade fan unless it is broken.
how many blades does it have. 4, 5, 6 or 7?
look at coolcraft.com
the ac condenser in front of the radiator reduces air flow to the rad mainly at highway speeds.

What kind of shape is your radiator in? Use a laser thermometer and check the temperature at the top and the bottom of the radiator. There will be a difference but if the radiator is blocked or flowing poorly, it will be a big difference.
