If engine coolant leaks onto the hot engine exhaust manifold from the top of the engine, an engine compartment fire can result.
Recalled Vehicles:
1993 Mazda Rx-7; 1994 Mazda Rx-7
Component: Engine And Engine Cooling:cooling System
Manufactured by: Mazda (north America),inc
Affected Units:: 12,316
Recall Summary:
The radiator cap pressure relief valve release pressure is set too high. This can cause the coolant to reach temperatures that exceed the thermal design limits of some components of the coolant system. Should this occur, engine coolant can leak collect on top of the engine.
How to Fix:
Dealers will inspect the vehicles and if any vehicle exhibits coolant leakage or if the coolant level has dropped to the point where the coolant loss would be sufficient to trigger the coolant level warning system, components potentially subject to deterioration from overheating would be replaced. These parts include the water pump bearing housing, the water level sensor and radiator upper hose, the thermostat gasket, and all water hoses located above the engine. In addition, all vehicles in which those components are replaced would also have the cooling system and other systems that carry flammable liquids checked to make certain that engine overheating had not caused any problems in those systems. Any identified problems will be repaired. The radiator cap, filler cap, and filler cap body of all recalled vehicles will be replaced by newly designed parts.
