How to Flush the Radiator in an Oldsmobile Alero
Flushing the radiator in your Oldsmobile Alero every other year is important if you want to keep the radiator in a good working condition and to keep your vehicle running smoothly. You do not need to be an auto mechanic to flush a radiator, just some materials that can be purchased at your local auto parts store.
Things You'll Need
- Distilled water
- Sealable container
- Long-sleeved shirt
- Wear gloves and a long sleeved shirt to protect your skin from coolant spills.
- Park your vehicle on an even surface and apply the parking brake. Open the hood of your car and feel the radiator to see if it is has cooled down. If the radiator is still hot, you must wait for it to cool off.
- Rotate the radiator cap counter clock wise once and then take a step back. Remove the cap after approximately one minute. If the cap area is smoking or hissing, wait a little longer because the radiator can spew coolant and injure anyone nearby.
- Touch the radiator hose and feel for any pressure. If you do feel pressure or tightness, wait until the coolant flows down the hose before attempting removal of the hose. The Alero does not have a radiator drain plug like other vehicles, so you need to remove the hose in order to drain the radiator.
- Place an empty bucked under the radiator and directly below the low end of the radiator hose.
- Remove the lower portion of the radiator hose and allow the fluid to drain into the bucket. Once you have fully drained the radiator, pour the fluid into a container that can be sealed. Remember that animals that drink this fluid can become violently ill or even die, so dispose of the fluid properly.
- Remove the entire radiator hose and replace it with a new hose.
- Flush the radiator by filling it with distilled water. Remove the bottom portion of the new hose and drain the distilled water into a bucket. Keep repeating this procedure until the water runs into the bucket free of debris.
- Add new coolant to the radiator until full and replace the radiator cap.
- Start your car and let it run with the heater on high for approximately 10 minutes. Wait for the radiator to cool off and check the coolant level. If needed, add more coolant.
