![]() In case if there is too much pressure buildup in the system due to trapped air or other failures, the coolant in the expansion tank will be pushed out through the overflow hose. When the system cools down, the vacuum inside the system sucks back the coolant from the expansion tank. When the pressure inside reaches above 15 PSI, the pressure cap valve is activated and the coolant flows to the coolant tank until the pressure gets to a normal level. The radiator cap consists of a spring-loaded valve mechanism which will respond to higher pressure. Here comes the role of the radiator pressure cap. Heating liquid inside a closed system always builds up pressure, so how to maintain the pressure? The pressure cap plays a vital role in the cooling system. The radiator consists of an inlet port, outlet port, a drain plug, and a radiator pressure cap. The radiator acts as a heat exchanger and is used to transfer the excess heat created by the engine into the atmosphere. The serpentine belt also drives the power steering pump, alternator and AC compressor. The impeller is driven by the engine drive belt through a pulley. The pump consists of an impeller, a pulley flange, and an O-ring. The water pump is the heart of the cooling system which pumps the coolant through the system with the help of the radial impeller which is driven by a serpentine belt. For sustained operation, these excess heat should be removed from the engine and kept at operating temperature. Here are the main cooling system parts and how they work: 1. A lot of heat is generated due to the combustion gas and the friction of mechanical parts. Main Cooling System PartsĪ car engine is basically an internal combustion engine where power is generated through the expansion of high-temperature and high-pressure gases.

Make sure to locate and repair the coolant leak before your engine overheats. Don’t risk overheating your engine.Ĭonclusion: It is not safe to drive with a coolant leak because you need coolant to keep your engine from overheating. If the leak is too great, call a tow truck. So, if you notice any leak coming from the cooling system, make sure to take your vehicle to the mechanic and get it repaired. This will result in engine overheating.Īn overheated engine costs a lot to repair. If there is even a slight leak in the cooling system, the coolant will leak out and there would be no coolant left to remove the excess heat from the engine. The cooling system is in charge of removing the excess heat from the engine and keeping the engine at operating temperatures. But, if treated on time, you can avoid some big repair bills. Have you ever had a coolant leak and you just ask yourself is coolant leak normal or is coolant leak dangerous? Is it safe to drive with a coolant leak? The coolant leak can never be a good thing. Is It Safe To Drive With a Coolant Leak.Do not use in a dirty or partially clogged radiator.Check fluid frequently, top off as necessary Fill with Prestone 50/50 Antifreeze/Coolant. Run engine at the highest heater setting for 10 minutes after reaching normal operating temperature.For systems larger than 12 quarts, use two bottles With engine off and cool, shake well and add entire contents to radiator and fill with Prestone® 50/50 Antifreeze/Coolant.Boosts corrosion inhibitors to protect against pitting & corrosion, which cause radiator leaks.Seals even large leaks without interfering with the flow through the radiator & heater core tubes.What makes this possible is the size, strength, & durability afforded by fibrous particles, the same materials in bulletproof vests. ![]() Unique combination of natural & synthetic components provides the ability to seal leaks up to 0.016" x 0.5". ![]() ![]() What makes this possible is the size, strength, & durability afforded by fibrous particles, the same materials in bulletproof vests.
