I have recently ordered a Ram spec header/expansion tank with filler cap
There are two outlets (excluding the cap neck overflow), one is a bleed connection to top of radiator RHS, the other is to be tapped into the main tube from thermostat to top LHS of rad and is for filling.
Thing is they are just 3/8 which is fine for the bleed connection but seems seriously slow for filling. I would expect to disconnect hose from stat and fill there. Also, it is a pain to route and plumb the filling 3/8 hose so I want to leave it out.
So question is: is there any disadvantage to speccing the tank with just a bleed connection to rad? I hope this would handle any expansion and contraction of coolant and would probably be OK to occasionally top up coolant. It would also provide the path into the pressure of the system to allow the cap to function. So is there any advantage with 2 outlets?
Sorry if this is a stupid question!
