Hey guys change ur coolant

I broke one of the hoses while doing OFH gasket so I swapped the hose out (5 hrs) and drained the coolant (looked light greenish and clean though) and refilled with bmw with 50% distilled water mix, and now being a 90 deg day yesterday with ac on and stop go traffic my temp won't even hit 240, more so stayed at 235 while cruising, before it would always stay closer to 250, I even changed to aggressive map and still same, happy camper thank you God
