Can a coolant overflow tank be added to an older rig and mounted higher than the existing brass expansion tank that is at the top of the radiator? The only place available is a shelf just above and forward of the radiator. If this can be done, what changes need to be made to the cap so coolant will flow in both directions and will the system still be pressurized?
The rig is a 1971 motor home that was a factory conversion of a Ward school bus shell. The engine is a 532 cu. in. Ford gas pusher coupled to an Allison 6 speed transmission.
Thank you,
