I changed the coolant on my bird today. Now the temp light is intermittently coming on, though I doubt the engine is overheating. Never happened before even in summer. What could I have possibly done simply by changing the coolant? Is it possible I messed up the thermostat just by this simple fluid change? (I just drained coolant, refilled with water and ran for 10 minutes to flush, redrained, and then filled with good old green glycol-based coolant (Prestone). Easy answer/solution? Give it more time to sort itself out over the winter? Thanks
