Does the Radiator of a Car Pull Coolant from the Reservoir?<\/a><\/em><\/strong><\/p>\n\n\n\nHow to Inspect Radiator Cap for Fault<\/h2>\n\n\n\n
Let\u2019s say that you\u2019re facing one or multiple of the symptoms that we\u2019ve mentioned right now. <\/p>\n\n\n\n
Even then, there\u2019s no saying that you\u2019re suffering from a bad radiator cap. Vehicles are very complicated and different components can lead to similar symptoms. <\/p>\n\n\n\n
Visual Inspection for Debris<\/h3>\n\n\n\n
So, it\u2019s important to check the component itself for fault. To check the radiator cap, you need to remove and inspect it. <\/p>\n\n\n\n
Before you get into that, remember that you\u2019ll suffer from burn damage if you try to open the seal while the vehicle is running, because the radiator usually heats up a lot. <\/p>\n\n\n\n
It\u2019s wise to let your vehicle idle while turned completely off before you attempt to open the seal. <\/p>\n\n\n\n
The first thing you look for is debris stuck on the radiator cap. Sometimes, the dirt and grime can prevent the cap from creating an effective seal, which ultimately leads to the mentioned problems. <\/p>\n\n\n\n
In such cases, simply cleaning the radiator cap will solve the issue. If the radiator cap still fails to create an effective seal or if it seems broken completely, then you\u2019ll need to get it replaced. <\/p>\n\n\n\n
When looking for an aftermarket radiator cap, it\u2019s important to make sure that the cap meets the required pressure specifications of your vehicle. <\/p>\n\n\n\n
Otherwise, you\u2019ll end up creating low or high pressure inside the cooling system. <\/p>\n\n\n\n
Pressure Testing<\/h3>\n\n\n\n
If you keep facing these problems even after making sure the radiator cap is well functioning, then it\u2019s time to check the reservoir for cracks and other potential leaks. <\/p>\n\n\n\n
Firstly, check the pressure of the system with a pressure tester. Let the engine cool down, and open the hood to find the radiator cap. Now, attach a pressure tester to the neck of the radiator or at the joint where the cap is installed. <\/p>\n\n\n\n
You need to look into the vehicle\u2019s manual to find the recommended pressure for the radiator, which is usually somewhere between 13 to 16 psi. Pump the tester till it reaches that point. <\/p>\n\n\n\n
Once there, stop pumping, but keep an eye on the gauge and let it rest for a while. If the pressure goes down within a few minutes, then you can be certain that there\u2019s a leak in the system. <\/p>\n\n\n\n
However, it doesn\u2019t necessarily signify that the radiator cap is faulty. <\/p>\n\n\n\n
Cracks in the reservoir, hoses, or gasket can lead to similar symptoms. So, if you\u2019re confident that the cap is well functioning, you\u2019ll need to check the other components as well. <\/p>\n\n\n\n
Changes in Coolant Level<\/h3>\n\n\n\n
In case of a bad radiator cap, there\u2019s a high chance that the coolant level will drop after a certain time. So, if you\u2019re suspecting a bad radiator cap, you should keep an eye on the coolant level. <\/p>\n\n\n\n
If you find a significant drop in the coolant level within a short time, there\u2019s high chance the radiator cap is faulty and needs a replacement. <\/p>\n\n\n\n
Coolant Smell<\/h3>\n\n\n\n
A leaking radiator usually leaves a smell of coolant behind. So, if you\u2019re around your car and can smell coolant, you better take a look at the radiator cap. <\/p>\n\n\n\n

Replacing a radiator cap is usually inexpensive, as it should cost you $25. However, you\u2019ll need to spend more if you want an advanced radiator cap with a built-in coolant temperature sensor. <\/p>\n\n\n\n
How Often Should You Change Radiator Cap?<\/h4>\n\n\n\n
Radiator caps are built sturdy, but it\u2019s best if you replace them every five years. This way, you can ensure maximum engine health and longevity. <\/p>\n\n\n\n
Does The Radiator Cap Release Pressure?<\/h4>\n\n\n\n
Yes, the radiator cap is designed to release pressure once the internal pressure goes beyond the specified point. <\/p>\n\n\n\n
Conclusion <\/h2>\n\n\n\n
Bad radiator cap symptoms<\/strong> aren\u2019t hard to read. The problem is, these symptoms don\u2019t necessarily indicate a faulty radiator cap, as they can be caused by leaks in the cooling system in general. <\/p>\n\n\n\nIf you keep experiencing the mentioned symptoms even after successfully fixing or replacing the radiator cap, you should check other components that may be causing the leak.<\/p>\n","protected":false},"excerpt":{"rendered":"
