7Few Signs Of A Failing Radiator Cap
Coolant Leak:
In addition to moving pressure and heat away from the coolant and engine, the radiator cap makes sure the coolant stays where it needs to be: inside the engine. So, if the coolant is leaking, there could be something wrong with the cap.
As pressure builds within the radiator, the coolant will start to push its way through the areas around the radiator cap, as well as the engine gaskets and hoses. In older vehicles, you may even see coolant leaking from the water pump.
Collapsed Radiator Hose:
The hoses connected to the radiator and expansion tank work like a vacuum. They push the coolant through the system to help the engine maintain a safe temperature. However, if there’s a problem with your radiator cap, the hoses may collapse.
A collapsed radiator hose looks a bit like a flat tire and is caused by excessive internal suction. If you pop open the hood and see a collapsed radiator hose leading to the expansion tank, chances are the cap isn’t letting the coolant from the expansion tank back into the cooling system.
Overfilling Coolant Reservoir:
Coolant goes into the reservoir tank as it expands. The cap is released by the pressure and the coolant is sent toward the overflow tank. If you have a bad cap, the coolant will get released too quickly and cause the reservoir to boil over.
Engine Overheating:
As soon as you notice signs of a coolant leak, you’ll want to head to a service center for repairs and maintenance. Waiting a little longer to schedule your service appointment can turn that leak into an overheating engine.
When it’s working properly, the radiator cap helps normalize the pressure within the cooling system and keeps the engine cool. If the cap can’t maintain the correct pressure for your vehicle, the engine will start to overheat.
An overheating engine could also be a symptom of air pockets within the cooling system. If the radiator cap doesn’t have a good seal, air can make its way into the system, creating little pockets. Air pockets prevent efficient coolant circulation, resulting in an overheating engine.
