Is over heating won’t stay cool

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Buying a 2004 Mazda 6 with an overheating issue for $600 might be a gamble, but it could pay off if you’re up for a bit of mechanical work. Overheating can stem from multiple sources: a failing water pump, thermostat, clogged radiator, or even a blown head gasket. With it having sat for months, there’s also a risk of corrosion or sludge buildup in the cooling system. Before buying, check for signs of head gasket issues, like white smoke from the exhaust, milky oil, or coolant loss. If it’s just a cooling system part (radiator or thermostat), it might be worth the buy. But if the engine itself has taken damage, the repairs could get pricey.
