The coolant goes to the heater core and, then, the engine block.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What are symptoms of a coolant leak?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A few signs will present themselves when your car has a coolant leak.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These are some symptoms you may notice:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Visible coolant leaks:<\/strong> Sometimes coolant leaks can\u2019t be seen.

The inspection is followed by a coolant pressure test, which allows us to see leaks.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A variety of tests may be used to locate internal leaks, such as a block test.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Can you drive a car with leaking coolant?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A vehicle that has a coolant leak will technically drive, but not for long.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You should avoid using a car that\u2019s leaking coolant, because it will overheat. If a vehicle runs too hot, it can lead to engine damage. The head gasket could blow, and after it blows the car won\u2019t run right.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In severe cases, driving a vehicle with an overheating engine will warp the surfaces of the motor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because of the damage that can occur, you don\u2019t want to put off a coolant leak repair. If your car has a coolant leak or you\u2019re noticing symptoms of a leak, have it checked out by an automotive expert as soon as possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">HomeTowne Auto Repair &amp; Tire is an authorized Michelin and BFGoodrich tire dealer located near Dumfries, Virginia.
