The next step is a bit trickier so you need to check carefully for eventual bleeder holes. If you got here, congrats, you;ve just eliminated air from your cooling system. To make things faster, turn the interior heater to maximum, than pour coolant into the radiator and wait until it starts to bubble. It is easily spotted on the water box, since nearby is the thermostat. The cooling agent from the radiator keeps going in circles through the hoses, into the engine and then back into the radiator where it is cooled down, and so on. In this moment the coolant level should drop as the trapped air is slowly leaving the cooling system with the boiling coolant. This may cause the thermostat to close or open incorrectly, or the water propeller to spin freely in a complete dry chamber. Remove the bolt and Stainless Steel Fastener fill up the reservoir to its limit and then you can head for the radiator.
That usually has catastrophic results, from exploding fuses to melted wires, resulting in a whole week in the shop, lots of headaches and a lot of money spent for nothing. Place the shift on neutral while making sure that the emergency brake is pulled. Any obstruction could lead to an inefficient cooling which may result in engine overheating. If you see the engine;s temperature rising fast, park quickly somewhere and pull the emergency brake. If you see coolant drops than you need to replace the bleeder bolt and the radiator cap. Than remove the radiator cap. Wait for the thermostat to open and heat the hose. Watch carefully if any coolant escapes the bleeder hole. Thankfully any vehicle owner can simply eliminate the air inside the radiator by following some steps. If any of these problems occur, are enough to permanently destroy your engine since overheating comes in a couple of minutes after the cooling system failed. Let the engine heat until the electric cooling fan activates.
Check out your car manual to see what kind of bleeder valve you have. Continuously watch the bleeder hole as you pour coolant in the radiator. For that to happen, the cooling system must be in perfect condition. Stop when you see leaking coolant and then tighten the bleeder bolt. If you can;t see any holes than get a floor jack and lift the front of the car. If you don;t have any spilled coolant, than start the engine and let the engine reach its normal operating temperature, in order to get the thermostat to open. Sometime that pressure is no longer balanced when air gets trapped in the system and prevents the coolant from flowing constantly. It will look like a small air bleeder bolt with a hex head fitting. Pop the hood open and remove the overflow cap.
Fill the radiator up to its neck with coolant, than head for the overflow reservoir and fill that up as well, replace the caps and then turn on the engine and let the cooling system do its job. In a sealed system, coolant will circulate constantly with normal pressure..If there;s one thing you need to make sure at all times whether you;re on the move with your car or your engine is simply idling, is that the engine needs to be kept cool at all times. On of the main problems that usually occur in the cooling system is the phenomenon known as air lock, if this happens, here are a few steps to eliminate it, thus preventing further damage to your cooling system and engine
