Checking Your Car Fluids - Engine Coolant
by All Vovo on 08/01/11
Radiator fluid, or coolant, is the most important part of your car's cooling system, which protects your engine from overheating. Low coolant can lead to a breakdown and expensive repairs. Always keep the coolant level full. Low coolant level causes engine overheating.
How to check the engine fluid level:
Check the level of coolant or antifreeze only when the engine is cold. The coolant level should be between "LOW" and "FULL" marks in the coolant overflow tank. If it's lower, you should top it up. If there is no coolant in the overflow tank at all, you should add the coolant into the radiator also. But, remember: Never open the radiator cap when the engine is hot!
Check the coolant strength with a coolant test strip. The strips change color to indicate how much life is left in the coolant. IF the coolant is brown or rust-colored, you may need a radiator flush and refill.
