Hello, I have a 1994 Fiat Uno with a 1.5 engine. I’m trying to replace the radiator, but I can’t find the model that has the outlet for the coolant reservoir/expansion tank. I’ve been looking at some newer or currently available models, and none of them have this outlet for the reservoir. Would using the radiator without the reservoir affect performance or cause any similar issues?
