A radiator can be cleaned by first opening the petcock (radiator drain valve) and draining the existing coolant fluid from the radiator. Once all of the coolant has been drained, close the petcock and fill the radiator with water. Flush the radiator by opening the petcock and draining the water from the radiator. Add new coolant and bleed the air from the radiator. Bleeding is done by leaving the cap off the radiator, starting the vehicle and letting it run for about 15 minutes. After the air has been bled, add additional coolant and replace the radiator cap.Continue Reading
Allow the engine to cool for at least two hours before starting the cleaning process. Open the radiator petcock and drain all the fluid into a pan for proper disposal. Close the petcock.
Using water or a radiator flushing solution fill the radiator. Once full, open the radiator petcock and drain. Capture the fluid and dispose of properly. Close the petcock.
Fill the radiator with new coolant fluid. Bleed any trapped air in the radiator by leaving the radiator cap off and running the engine for about 15 minutes. After bleeding, add any additional coolant fluid as needed and replace radiator cap.
To add coolant to a car, open the hood, and remove the cap on the white plastic tank that is next to the radiator. Add a 1:1 mixture of coolant and water up to the full mark, and replace the cap.Full Answer >
The buildup of pressure caused by adding too much coolant to a car can cause the rupturing of hoses, internal pipes and even the radiator. When coolant is added to a car, it is cold, however, while the engine is running, the liquid starts to expand, causing a buildup of pressure. If the radiator is too full, this buildup of pressure is often too great for the internal workings of the car.Full Answer >
A radiator diagram starts with the filler cap on top, through which the user adds radiator fluid as needed. The flow of the fluid depends on the radiator's positioning. The front of the radiator includes cooling fins for air flow. The side contains the core tubes and, toward the bottom, the transmission oil cooler. The back of the radiator includes the inlet and outlet valves that attach to the engine.Full Answer >
To fix a leaking radiator, use a radiator sealant. Pour the radiator sealant into the radiator. When a radiator sealant is applied to radiator walls, a coating is formed over any small holes that cause the leak.Full Answer >
