To cleanse the radiator and remove any residual residue from the old coolant or antifreeze, use a hose to fill the radiator with new water and replace the radiator cap. After that, start the engine and let it run for 15 minutes. Then, turn off the engine and let it sit for another 15 minutes before removing the radiator cap. The steam that comes out of the valve will help loosen any residue in the tank. Also, be sure to wash your hands after touching the radiator!
If you're looking to change the color of your car's cooling system, there are several options available today. Most cooling systems can be painted with high-quality automotive paint. If you want to go this route, look for instructions on how to prepare the vehicle for painting. You may need to remove parts of the interior such as seats and carpets to get a better look at what needs to be painted.
Another option is to replace the entire cooling system. This is best done by a professional auto repair shop but can be done by someone who has knowledge of cars' internal components.
Last, you can buy coolants in different colors. These usually come in red, white, or blue. They're not meant to be mixed together though, so make sure you purchase the correct color for your vehicle.
By opening the drain valve on the bottom of your radiator, you may empty the coolant from it. Then, drain the coolant from your engine block by also opening the block drain. Allow the car to run after adding the bought radiator flush to the radiator. Drain the old coolant, and your automobile is immediately clean and new.
If you locate a leak in your cooling system, open up the hose connections at both the radiator and the intercooler, and let some air into these components. This will help prevent any more coolant from leaking out of the system.
Make sure that all of the hoses are tight to the vehicles body before driving away from the scene. Hose lines can be damaged by heat, so make sure that you don't leave them inside of a parked vehicle. Also, make sure that you shut off the fuel line when you're done working on the car.
Coolant blocks occur when debris such as sand gets into the flow path of the water pump. This prevents the impeller on the pump from turning, which causes the water pump to malfunction and fail. When this happens, the computer will switch over to an alternate method for pumping water through the system called "hot-wire mode".
While draining the radiator will remove most of the old antifreeze, it may also leave some coolant and impurities behind, which may mix with and contaminate your new antifreeze, causing overheating. You want a complete flush, a forceful elimination of everything old to create room for fresh fluid. This can be done by removing the access panel on the driver's side floorboard, if there is one. Otherwise, you'll have to take the passenger-side floorpan off.
The best way to do this is with a garden hose while you're the car is still running. Open both radiators simultaneously for maximum drainage. Then shut off the car and let both tanks fill up with cold water. Don't forget the belt buckle! After 15 minutes or so, turn the key to start the car. If the temperature rises above 160 degrees F after starting the engine, add more coolant until it stays below 160 degrees F. The rule of thumb is that you should be able to touch the metal part of the heater core without injuring yourself. If it feels warm, then more coolant is needed.
If you don't have time for this extensive job, there are other options. Most major auto parts stores sell approved kits for replacing heater cores. These usually include all the parts you need except for the rubber hose that connects the cores together. The kit may also include a funnel to help drain out as much old fluid as possible.
