Coolant options
Lots of options here and I thank you all for the suggestions. Now heres why I ask. I have a 66 Dart with a 408. Automatic trans with cooler in front of the passenger half of a brand new 3 core aluminum radiator. I have 2, 9" electric fans which are mounted in a shroud that completely covers the inside of the radiator ad is sealed off very well. The fans are pullers and move what feels like a lot of air. I have a 50/50 mix of water and antifreeze. The motor is fresh and has only been on the road for 7 miles. My temp gauge is an Auto Gage with an actual sending unit that is mounted in the front of the intake in the tapped hole just behind the thermostat.
So during the first road drive my temp went to 210 on the gauge. When it shoot it with the infra red gage it reads 10-15 degrees cooler. After it sits a few minutes it seems like the carb has flooded or vapor locked. I have purchased a cool plate for under the carb but havent put it on the car yet. My worry is that it was only 60* the night I drove it so I am sure in summer heat its going to get even hotter.
Oh a few other things, the thermostat is a 185*, and the water pump was the one called the sport which was supposed to move more coolant thru faster.
I dont think there is room for a blade fan or a fan clutch.
The water pump did not allow for a larger single fan to be installed as I did try that at first. I did some research trying to find a shorter nose pump but I had no luck. The fans are running with an over ride switch that I turn on as soon as I start the engine.
So Im just looking for a way to bring my temp down as it runs.
Thanks for all the suggestions.
