I have an overheating problem the gauge needle reaches the third line. The fan clutch is new, I eliminated the thermostat, I took the radiator to get fix because it was clogged and obviously changed the engine coolant. But I keep thinking why the car overheats and the engine fan clutch doesn't goes hard. The electric fan works both speeds but the fast speed switches on it doesn't come off meaning that the coolant is not cooling. Can anyone help ?
Sometimes the fins just rust away until there is hardly any water movement.
You'll see flow, but it's not [I]enough[I] flow
I know this from experience... "I'm in Florida, I don't need anti-FREEZE!"
Well, there are rust inhibitors in the coolant, and corrosion may be the culprit.
Someone, alone the way might have let the antifreeze go too long.
