What happens when you have a bad radiator cap?
Because the engine depends on the heat absorption capacity of the coolant in the radiator when you drive a car with a faulty radiator cap the car will overheat. The car overheats because the pressure I the radiator is too low for it to contain all the heat generated by the engine.
What causes antifreeze to leak from the radiator?
Antifreeze Leak Causes. Listed here are common causes for your coolant to be leaking: If the radiator cap doesn’t no longer fits as it initially did or if it is weak and wore out it can cause loss of your systems coolant by way of the overflow tube, and it will happen every time you run the engine very long.
Where does the coolant go after draining a radiator?
Instead, a pressure cap is fitted to the system, and a tube leads from the top of the radiator to a glass, plastic or metal tank or container. Coolant which has expanded as the system warms up passes down the tube into this tank, and is drawn back into the radiator when it has cooled.
How to refill a fully sealed car radiator?

Where is the coolant cap on a car?
The most important thing when checking coolant is you need to let your car cool down before you open the system. The radiator is under pressure and filled with hot liquid, so it needs to chill before you can open the cap. On some vehicles, however, the coolant check cap will be located on the coolant spillover reservoir.
What are the symptoms of a bad radiator cap?
The radiator cap ensures that this pressure remains constant. There are several symptoms of a bad radiator cap like leaking coolant, the appearance of white streaks, and hose bursts caused by coolant pressure fluctuations. Excessive pressure causes cooling system component failure while less pressure could lead to the liquid coolant boiling off.
Is there antifreeze on the radiator cover?
I SMELLED ANTIFREEZE SO I CHECKED UNDER THE HOOD AND SEEN DRIED ANTIFREEZE SPLATTERED ALL OVER MY ENGINE COVER and radiator fans .. I checked the reservoir to make sure it wasnt cracked and its good i poured water less than 3 hours ago and it dried up ..
What kind of coolant do you put in a radiator?
The radiator expansion tank should be clear and the coolant level can be checked by looking at the tank fill level markings on the side on the tank. This fluid is a mixture of coolant and distilled water. Note: Refer to the owner’s manual of your car to see the coolant specifications for your vehicle. Step 1: Locate the overflow tank.
