Sunbeam with 2.3 Ford and A4LD

Okay I am back. After a bad head gasket on the 200 six Mustang and fixing "honey-do's" I am back on the sporty car. I realize I joined almost a year ago so I will be donating again soon and hopefully posting pictures of progress. The engine compartment is small so I am wondering if anyone has had problems keeping things cool under the hood. My 65 Mustang six gets hot and sometimes percolates/vapor-locks the little one barrel...even with a heat sink under it and six blade flex fan. Just wondering how others fixed their heat problems!?

I forgot to say I got the A4LD with lockup torque converter so a button on the shifter will be used to lock it up once in 4th gear. A computer did it automatically in the Mustang but the Beam will not have electronics. My degree is in electronics and after 30 or so years chasing electrons I am done with that stuff! You can't see the little buggers without special tools but mechanical stuff is visual! Those points are burned! That rotor is bent! The plugs are fouled! The high-speed jet is plugged! After hooking up a code-reader one might be pointed in the right direction with computer controlled injection/timing but even then "Is it the O2 sensor, or is the computer on the fritz THINKING it is the O2 sensor?" Anyway, at best I will have a magnetic triggered distributor but keep POINTS in the trunk...just in case!

Two of the biggest issues with keeping it cool ( especially at low speeds, in traffic! ) are getting the trapped hot air out from under the hood (bonnet) and air bubbles in the upper radiator hose. If the radiator cap is lower than any part of the cooling system, this can cause air bubbles. One cure can be found at Summit Racing or Jeg's - a filler cap that fits in the upper radiator hose. This item is basically a short length of metal tube with a filler neck in the middle of it. One cuts the upper radiator hose at it's highest point, installs the tube/filler, and a radiator cap that is rated a pound or 3 lower than the cap on the radiator. If you have room, a surge tank can also help.

Either ceramic coating the headers or using a wrap like DEI can help keep exhaust heat in the pipe and out of the engine compartment. Louvering the hood ( bonnet ) will help get heat out as well. - if you don't want to do that, perhaps louvers or vents in the inner fenders will help. Of course, a strong electric fan is a must !
Hope this helps !

CJ is in the process of moving at the moment and I'm sure he will return as soon as he gets his head above water.
