After having my old radiator changed with a brand new one (because of a crack), it seems as the engine (coolant) temperature is not as stable as before.
Old radiator 'stats':
Almost always stable at 90°C (194°F)
This includes standing still in traffic for a couple of hours. It would maybe change a few degrees. When cruising at 120KM/H (74.56MP/H) it would also stay at almost exactly 90°C.
Now with the new radiator it feels as if when cruising it stays somewhat stable at 85°C. (185°F) and standing still in traffic it bumps to 93°C ish (199°F)
These numbers aren't scaring me, but the fact that the second I can start driving after standing still, it goes down rather fast.
It's never really stable, if that makes sense.
Could this be because some air-ways were blocked on the old one?
Would a new one cool better or faster? (I assume this is the one)
Again, the numbers are 'fine', but the fluctuation is what caught my eye.
