How to flush antifreeze on 2000 Dodge RAM 1500?
You will need the following material to flush the antifreeze –
- New antifreeze – Make sure to use the correct type of antifreeze for your RAM 1500.
- Distilled water – Using distilled water will help prevent mineral build up in your cooling system.
- Cooling system flush – It helps to remove contaminants from your cooling system.
- Funnel – This will make it easier to pour the new enterprise into the radiator.
- Socket wrench – You will need this to remove the drain plug from your radiator.
- Large drain pan – This will catch the old antifreeze as it drains.
How to flush antifreeze on your 2000 Dodge RAM 1500?
- Park on a level surface – Make sure your truck is parked on a level surface this will help prevent the old antifreeze from spilling.
- Allow the engine to cool down – Let the engine cool down completely before starting the flash. A hot engine might get you injured.
- Locate the radiator drain plug – Open the hood and locate the radiator. The drain plug is usually located at the bottom of the radiator.
- Place the drain pan – Place the drain pan underneath the radiator to catch the old antifreeze.
- Remove the drain plug – Use the socket range to loosen and remove the drain plug. The old antifreeze will begin to drain.
- Add cooling system flush – Once the old antifreeze has drained, add the cooling system flush to the radiator according to the instructions on the package.
- Feel the radiator – Fill it with distilled water.
- Start the engine – Start the engine and let it idle for 20 minutes. This will allow the cooling system flush to circulate through the system and remove contaminants.
- Drain the system again – Turn off the engine and allow it to cool. Drain the system again using the same steps as before.
- Fill with new antifreeze and water – Feel the radiator with a mixture of new antifreeze and distilled water. Consult your owners manual for the correct measurement.
- Check the antifreeze level – Start the engine and let it run for a few minutes. Check the antifreeze level in the radiator reservoir. Add more if necessary.
What antifreeze is best for RAM?
Choosing a right antifreeze is very crucial for maintaining your truck’s optimal performance and preventing damage. There are two primary types of antifreeze –
- Conventional antifreeze – This is typically green in colour and it provides adequate protection for most vehicles but may need to be replaced more frequently.
- Extended life antifreeze – It is also known as HOAT (hybrid organic acid technology) or OAT (organic acid technology). It is typically Orange or yellow in colour and it offers longer service intervals. It is formulated to provide superior protection against corrosion.

Now there are several factors that you need to consider before choosing the antifreeze for your truck –
- Climate – If you live in a region with extreme temperatures, you may need an antifreeze with a lower freezing point and a higher boiling point.
- Vehicle age – Older vehicles may require different types of antifreeze than newer models.
- Previous antifreeze use – If your Ram has previously used a specific type of antifreeze, it is generally recommended to continue using the same type to avoid issues.
By considering the factors you can make an informed decision about the ideal antifreeze for you.
How often should you change coolant in a Ram 1500?
Maintaining your Ram’s cooling system is crucial for its overall health and performance. One important aspect of the maintenance is regularly changing the coolant.

Typically you should change your coolant after every 30,000 miles or after 1.5-2 years.
Why is regular coolant change important?
- Temperature regulation – It prevents the engine from overheating in hot weather and freezing in cold temperature.
- Corrosion protection – Coolant helps protect the engine’s internal components from corrosion.
- Lubrication – It provides lubrication for the water pump and other components within the cooling system.
Regular coolant changes are essential for maintaining your ram’s cooling system.
Conclusion
Flushing the antifreeze in your 2000 RAM 1500 is a relatively easy task that can help to maintain long term health of your truck’s cooling system.
I hope you have got all the necessary information related to 2000 Dodge RAM’s antifreeze in this post.
