Hey guys! So had an issue with overheating in my Copen, took it to the mechanic and they said that plastic has gotten into the radiator and it needs to be replaced along with the radiator cap and the "overflow lid." I've been able to source the cap and the radiator but I can't locate anyone selling the coolant overflow reservoir? I don't know if I'm just searching for the wrong terms? I hope that makes sense, if anyone can point me in the right direction I will be very grateful. Thank you,
