I then (by accident) pumped the upper radiator hose that’s clipped at the oil filter housing and I could hear coolant running into the reservoir tank thru the small overflow hose. (see pictures & blue tape marks) So I squeezed the small overflow hose while pumping the radiator hose and could feel the coolant being pushed through and into the tank. Could another SRT owner do this to confirm?
Bottom line - I think engine and HE coolant flow together. Maybe not a lot but they do some co-mingling when the engine is running.
So I think even a small tank for the radiator (Like you are doing Steve) will be a good thing. Any separation would be good IMO.
Steve - since you have your front bumper off - do the hoses for the cabin heater run -or- tap into the system near IC pump? I was trying to trace them out but I am hoping you’ll have a better view.
Thanks

I don't think they connect anywhere in the I/C system, but I'll double check when I get home from work tonight. Brian, did you read what I said about the OEM overflow tank? I think there are six sections inside it, so I don't think I'll be able to pump from and into the tank with the I/C system.
