Just replaced with ac delco radiator and rinsed front of grill work twice since replacement.
Went for hour drive Wednesday and no stink sweet smell. Air temp 66 degree.
Today 84 degree and sweet stink smell at grill opening. What gives?
I do know I filled the overflow to the way top figuring some would be needed as air trapped escaped.

Did any of you guys have sweet smell after replacement?

When I did my wife's Radiator, Thermostat, and Waterpump I smelled the lovely smell of hot coolant until it finally burnt off the block. Took about 3-5 days for the smell to totally go away. Also make sure your vent line is sealed good. When I replaced the radiator I kept smelling coolant, and I even had a white stain down the fan shroud. Finally tracked it down to the vent hose not being tight enough. I cut some off the line, but it still leaked so I just used a small hose clamp and the problem went away.

If you filled the overflow to the top it probably poured out a bit, if not a lot. It runs down the inside of the fender liner and hits the engine, and often the exhaust manifold. So the smell would be normal.
