Auxiliary Transmission Cooler Placement
Hi all,
Recently purchased 70 dart swinger with original 340 motor and trans, though I was told the cylinders may have been bored out.
Currently working on fixing the over heating issues. In street traffic (25 mph, streetlights, etc.) water temp is approximately 220-230f, but a few seconds on the highway (45mph and above) temp is brought down to 190-210f. Pull of the highway and quickly goes back to 220-230f.
This makes me think this is an airflow issue. And I suspect one large issue is this 11”x11” transmission cooler mounted between the fan and the radiator. Shown below with shroud on and off. Note the fan currently sits about 3” from the radiator.
1. Is the transmission cooler necessary? Can i just pull it out and rely on radiator to cool transmission oil?
2. If necessary, should it be moved? Its current placement makes me think it is killing any airflow give its size and placement directly in front of the fan.
Thanks in advance. New member here!
