Q: How does engine coolant work, and how can I keep my engine from overheating on these extremely hot days?
Art's A: If your temperature gauge goes into the red zone, shut your engine off immediately! Although today's engines are designed to run over 200 degrees, they can not withstand overheating due to the high aluminum content. It is equally critical to use only the factory recommended coolant. Unlike the old days, there are multiple types out there and using the wrong type, or using a " universal" coolant can also cause major damage. Another thing is to mix the coolant according to the instructions. Using straight coolant out of the bootle can actually *cause* an engine to overheat. Most manufacturers now sell coolant "premixed". A properly serviced cooling system proves the old adage " an ounce of prevention is worth a pound of cure". -Hope this helps...Art.
