It is the correct one. Spectra Premium CU473 is the model and it a slight bit smaller then the OEM BEHR. I've driven it for a month and the coolant is full and has no air in it.

It's working. Just not the same way as the BEHR was, it's not as efficient at cooling the engine. Yes, it may only be 5-8 degrees off but that still bothers me. I'll do some further testing to confirm it's in fact the rad but at this rate, I'll just buy the OEM Mercedes-Benz one.

I'm from Canada and I'm running just below 100 at highway speeds in the winter time (-10 now), so who knows what the summer will bring engine temp wise. During city-driving temp is normal. I really don't want to overheat this engine, it's in mint condition and has compression of 360 on all 5 cylinders.
