My 66 fastback seems to be overheating on me, it is running about 220 in town. I have a Fluidyne alum radiator, Meziere 55gpm pump, and a electric fan that pulls 2900cfm. I took out the thermostat and have tried different flow regulators with little success. Any ideas?
The water pump is electric, so a belt driven fan is not an option. I thought that pullers were more efficient than pushers? I have removed the thermostat.
Have you checked your timing? How's your carb mixture? If your timing is late or isn't advancing when it should, it will get hot. Same goes for carb if it's very lean.
What brand of fan, I had a perma cool with the metal blades. I had some probs with overheating when I moved it to a puller thinking it would work better, but in fact those fans work terrible as a puller. If thats what you have, you might wanna try it as a pusher, I actually purchased a puller fan from Derale (sp?) and used the PermaCool as a pusher, worked nicely.
