- Hi Folks,
I guess I'll start off the season of temp related discussions! View attachment 128402 So my 68 Coupe is a victim of blazing hot under hood temps, especially when, or just after, using the air conditioning. As is becoming more & more common with the deterioration of quality in gasoline, this excessive heat creates a whole slew of issues. In my case, I get carburetor boil out, (leaving a flooded engine condition after parked for 10-30 minutes followed/compouded by a dry float bowl and or vapor lock, unless hood is left open), idle degradation while at a long traffic light, etc, etc! Bear in mind, these only really become a problem when ambient temps climb to 105 degrees and above (Sometimes near 120 & more at the level of 2 feet above the pavement View attachment 128403 ) Anyone have any good ideas to combat these issues? Ive been considering:
A-Finding a crap hood (Mine is a turn signal model) to butcher for louvers or a scoop to ventilate the engine compartment.
B-Adjusting hood hinges to allow the rear of the hood to live 1/2" to 1" above the level of the cowl. This looks like CRAP!
C-Electric fan, set to stay on for a while after engine is turned off. I realize this won't do a lot to lower the overall engine temp, but might be just enough to help evacuate an adequate amount of under hood heat. The real downside of this is the added toll it will take on the battery. Unless using a pricey "deep cycle" battery, the battery life is seriously compromised by repeated discharge & charge cycles.
I already have ceramic coated headers, a phenolic carb spacer, well placed clutch fan with a proper shroud and a good aluminum radiator.
Any Thoughts?
