Have a 1971 dart swinger, 318 have been having cooling issues put a campion 4 row aluminum rad in helped only a little.have not been running a resivior for rad. guy today said that is why I'm overheating, will that make a difference ?
All the reservoir does is allow the recovery of coolant pushed out while running, and it only does that as it cools down and causes a vacuum in the radiator.
It makes zero difference in cooling while running.
