DETROIT -- Ford is recalling more than 7,000 Escape SUVs to fix coolant leaks that can cause fires.

The recall affects 2013 Escapes with 1.6-liter, four-cylinder engines.

Plugs that fill holes in the engine may not have been put in properly and can fall out while the motor is running.

Coolant can leak and cause the engines to overheat.

Ford says it will add a sealant and put a secondary cover over the plugs at no cost to owners.
