67 Dart cooling issues
Hello all,
Summary
- Radiator - 3 row cross flow aluminum
- Water pump - 8 blade impeller
- Fan - 2400 CFM 17" electric
- Thermostat - gutted std flow 180 - basically a plate with a hole.
I'd try putting in a good 180 thermostat. We/I did a 65 b body that drove me nuts and it turned out to be the the case , we could let it idle all day long and it wouldn't overheat but if you drove it for any length of time it would heat up and keep on going, We put in a new 180 and it kept the heat down to 180 even driving in stop and go at the woodward dream cruise last year , basically the plate with a hole in it does not hold the coolant in the radiator long enough to cool it. I did later put the original fan and shroud back on instead of electric fans. Now it runs 175ish or so even in 100 temps. plus if I jump on it it will YANK the temps down to about 150 really quick. I'm thinking of trying a 195 thermostat to try and get it near 180/185
