Chased a coolant leak for 2 days, it was just a loose cap the whole time
My 2012 Civic started overheating near the freeway exit in Reno, so I replaced the thermostat, then the water pump, and even the radiator hoses over a weekend. After $180 in parts and two full afternoons, a buddy pointed at the reservoir cap and it fixed itself in 30 seconds. Anyone else have a 'simple fix' that made you feel like an idiot?
