NHTSA recall 94V094000
Engine And Engine Cooling · Mazda Motor Corp.
Details
What's wrong: 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.
Why it matters: If engine coolant leaks onto the hot engine exhaust manifold from the top of the engine, an engine compartment fire can result.
The 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.…
