If there are no other cooling passages or hoses near the head gasket you may be able to positively identify the leak as a head gasket leak, but if there are other cooling passages nearby, you may need to add a UV dye to the coolant then watch the head gaskets with a UV light to positively identify the leak. Bubbles in the radiator or coolant overflow tankĪ head gasket leaking external would cause coolant to come from below the intake or exhaust manifold and often only happens when the engine is completely warmed up.Coolant leaking externally from below the exhaust manifold.Since a visual inspection usually will not prove a head gasket leak, it is important to know the other symptoms so you can accurately diagnose a head gasket problem. Because much of the gasket can’t be seen without disassembling the engine, blown head gaskets symptoms can be very difficult to diagnose. Since the head gasket seals the coolant passage both from the atmosphere and the combustion chamber you can’t see much of the head gasket on a vehicle with the engine installed. To better understand why a head gasket might blow, check out this article on why head gaskets blow. This can happen regardless of the make or model of your car or the type of head gasket used. Due to the wide range of temperatures and relatively large surface area, it is not unusual for head gaskets to develop leaks over time. This means your head gasket has to seal both extremely hot, high-pressure combustion gases as well as engine coolant which can be anywhere from cold ambient temperatures to the normal operating temperature of your engine. The head gasket forms a seal between the engine block and the cylinder head. To understand the symptoms it can be helpful to understand why a head gasket might fail. Now that we understand what a head gasket it, it’s important to learn what head gasket failure symptoms look like to avoid higher expenses due to additional engine damage caused by driving with a blown head gasket. The head gasket also keeps coolant and oil out of the combustion chamber which is important for the same reasons you wouldn’t want coolant or oil leaking anywhere else. The head gasket is so important because it seals the combustion chamber allowing your car to build the proper compression and contain exhaust gases both of which aid in maintaining the efficiency of your engine. Every modern car has this gasket but they vary in their thickness and construction based on the manufacturer’s design of the engine. The head gasket lives between your engine block and cylinder head. Let’s start by talking about what a head gasket is. If you happen to own one of these vehicles, don’t worry it does not mean that you have a bad car or that you are going to spend lots of money.
