If your engine is running hotter than normal, check your coolant reservoir. If the coolant level is low, you may have a leak. Leaks in your cooling system can be an easy fix, like a failing hose or clamp, or they could indicate a bigger problem, like your radiator, heater core, or head gasket. Radiator stop leak and engine block stop leak products can often be used to seal small holes in cooling system components. Using these products is often as simple as pouring them into the radiator and running the engine. Check out our selection of radiator and head gasket sealer options at O'Reilly Auto Parts to simplify your repair.
