Before you begin your inspection, park your car first and turn off the engine. It will be difficult to check the radiator while the engine is still on. So get your car off the ignition and allow the engine to cool down for a period of at least two to three hours. Then, remove the radiator caps before moving on to the next step.
Why does my radiator leak?
It's usually due to a failure of the Seal between the plastic and the aluminum parts. the best solution is to replace the radiator. Sometimes a stop-leak product works, for a while, but in the long run you need a new radiator.
Why does coolant get pushed out of the radiator?
Another thing that can cause coolant to be pushed out is boiling of coolant. Remember that a major point of having a radiator cap is to keep the system under pressure in order to raise the boiling point of the coolant. If there is no radiator cap, coolant can start to boil within the engine after it has warmed up some. This causes a similar situation to air pocket formation. And as this boiling coolant makes its way out the system, it will similarly push coolant out the filler neck.
Why does my overflow tank overfill?
I read a few answers but none of them mentioned the thermostat. In my experience the thermostat is the most likely cause of the overflow tank to overfill. The fluid is being blocked therefore it's heating up to the point of actually boiling and then as it expands and the only place for it to go without causing a leak in the system is into the overflow tank and then overflowing out of that tank. If the problem is not fixed quickly you're going to experience a leak somewhere else in the system.
Why does my coolant boil at low temps?
If the temp is high and or you have high volume of gas discharge , you have a number of options. First old, contaminated, or improperly mixed coolant boils at lower temps. Next overheat issues due to a failed thermostat, clogged radiator, or failed head gasket.
What happens if your radiator is blocked?
If your radiator is partially blocked and causing coolant to go through it more slowly than it should, the symptoms should be variable with outside temperature and vehicle speed (whereas with a thermostat it should be pretty much the same under all conditions). For example, it will be hotter sitting in traffic than at highway speed.
Why does my head gasket leak?
First of all, remember that the cooling system of an engine is irregularly shaped. This causes the formation of air pockets in your cooling system when you fill it. Even if your engine has a bleeder valve to bleed a good amount of this air, there will still be SOME air pockets. Running the engine bleeds these air pockets to the radiator filler neck. And when this happens, coolant will be pushed out. This is perfectly normal, and will happen until all air pockets have been bled. It can
What is more common than an internally blocked radiator?
What is more common than an internally blocked radiator (though of course that does happen) is an externally blocked radiator where road debris and dried bugs are preventing air from passing through it and hampering its ability to cool things down. Visually inspect both the front and the back. If dirty, ou can literally take a garden hose to it and should notice a differnece immediately (if it is your problem). Even if it is not visibly dirty, make sure the air from the fan is passing through it to the engine side. And while we're on the topic of fans, make sure yours is working. That's also a much more common problem than an internally blocked radiator.
Why does my radiator leak?

What temperature should a radiator be?
Your radiator has to be able to function anywhere between ambient temperature (which varies depending on where you live) to over 200 degrees ! These drastic swings create thermal stress on the metal and plastic in the radiator, which can cause a radiator to crack or leak over time, regardless of how well you care for your vehicle.
How does antifreeze affect radiators?
As the antifreeze in your cooling system heats up it will expand and expanding fluids increase pressure in a closed system. Your radiator cap is designed to release pressure at a certain point, usually between 10 and 18 PSI. If your radiator cap is malfunctioning it can cause an overpressure in your system which can damage some of the more delicate components in your radiator. Radiator caps are usually inexpensive so consider replacing yours if you are worried about high pressures in your system.
Why won't my radiator fan turn on?
If your radiator fan doesn’t turn on it can cause high temperatures and pressure in your system, leading to cracks. On the other hand, if your radiator fan is spinning but has a bad bearing, the wobbly fan can contact your radiator damaging the tubes and causing a leak.
