We’re well into radiator season, but it’s never the wrong time to ensure your cooling system is in top condition. Boilovers and overheated engines are inconvenient or embarrassing at best, and crushingly expensive at worst. The air-and-oil cooled crowd might scoff with superiority, but a $5 radiator hose failure can result in $5000 worth of engine damage. As such, we put together a five-point cooling system checkup that could help prevent a meltdown during these sweltering days of August. Of course, be sure to start any cooling system work with the engine stone cold (preferably let sit overnight).
