Can you conversion guys tell me how your electric fans operate and if you've modified the air dam?
Put in my 15.5x28 Griffin radiator with 944 Turbo fans on a shroud. Crusin at 70 on the freeway the temp starts at 170 for 6 miles and creeps up to 195 when the fans come on and bring it back to 170. This continues to cycle like this both on the freeway and around town. I'm using a 160 Tsat until the cooling system is done. I ran with the lid off so I know the cuts in the wells are ok. So I figure I'm either blocking the airflow with the fans/shroud or the air dam need to channel the air in somehow. It doesn't seem to me like the temp should cycle like this. I'd like to hear how yours run. Thanks, Tyler '70 914/350/4 webers |

Tyler:
By the way, I forgot to mention that I have a HEADER TANK that is mounted as high as possible in the engine bay, just under the engine cover. The larger tube on the bottom of the tank feeds to a "T" in the water line coming out of the engine, and going to the radiator. Then in the intake manifold, next the the t-stat hosing, I fitted a 3/8" BLEED LINE to the top of the tank. With this setup, the air in the system AUTOMATICALLY bleeds out of the cooling water and collects in the header tank. I am running a standard 15 PSI cap. When I fired the engine a year ago, I did a basic bleed of the system, then filled the tank to the top, let puke out the excess leaving it 1/2 full and have NEVER had to add water since!! THIS IS OLD TECHNOLOGY and IT WORKS ......I learned it on my Dad's '64 Cobra! Actually, I am running the SAME tank from the Cobra!! Best of Luck, Terry |
