How To Add Coolant To Ram 2500 Diesel? Complete Guide

Adding coolant to Ram 2500 diesel is easy and only takes a few minutes. Make sure the vehicle is turned off and cooled down before beginning. Locate the coolant reservoir, which is usually found near the radiator, and unscrew the cap.

Fill the reservoir with a 50/50 mixture of water and antifreeze until it reaches the “full” line on the side of the reservoir. Screw the cap back on tightly and start up your Ram 2500 diesel to check that the coolant level is correct.

  • Park your Ram 2500 diesel truck on a level surface and turn off the engine
  • Lift the hood and locate the coolant reservoir, which is typically marked with a “coolant” or “low engine coolant” label
  • Remove the cap from the coolant reservoir and slowly pour in the new coolant until it reaches the “full” line on the side of the reservoir
  • Be careful not to overfill it
  • Replace the cap on the coolant reservoir and close the hood of your truck

Can You Just Add Coolant to the Reservoir?

If you find that your car is running low on coolant, you may be tempted to just add water to the reservoir. However, this is not a good idea and can actually cause more problems than it solves. Here’s why:

Water has a lower boiling point than the coolant, so it will start to boil sooner. This can lead to engine damage as the water turns to steam and gets into sensitive areas. Coolant contains additives that help protect your engine from corrosion and overheating.

Water doesn’t have these same properties, so it can actually hasten engine wear and tear. In short, it’s best to stick with coolant when topping off your reservoir. Your car will run better and last longer in the long run.

How Do I Add Coolant to My Dodge Ram?

Assuming you are adding coolant to your Dodge Ram 1500 (other models may vary), you will want to start by opening the hood and locating the coolant reservoir. The coolant reservoir is a large, plastic tank that is usually located on the passenger side of the engine bay, near the firewall.

Once you have found the coolant reservoir, remove the cap and check the level of coolant inside.

If it is low, then you will need to add more. To add coolant, simply pour it into the reservoir until it reaches the “full” line. Be careful not to overfill it, as this can cause problems.

Once you have added enough coolant, replace the cap on the reservoir and close the hood.

Adding Coolant To Ram 2500 Diesel

If you own a Ram 3500 diesel truck, chances are you’ll eventually need to add coolant.

Here’s a step-by-step guide on how to do it:

  1. Park your truck in a safe, level area and turn off the engine. Let it cool down for at least 30 minutes before proceeding.
  2. Locate the coolant reservoir (usually found near the radiator) and remove the cap.
  3. Slowly add coolant to the reservoir until it reaches the “full” line. Do not overfill!
  4. Replace the cap and start your engine. Check for leaks and ensure that the temperature gauge is working properly.

Ram 2500 Coolant Level

If you have a Ram 2500 truck, it’s important to check the coolant level regularly. This is because the cooling system in these trucks is under a lot of stress and can fail if the coolant level gets too low. There are two ways to check the coolant level in your Ram 2500.

The first is to use the dipstick method. Simply remove the radiator cap and insert the dipstick into the radiator. If the coolant level is low, it will be below the “full” line on the dipstick.

The second way to check your coolant level is with a hydrometer. This tool measures the density of liquids, so it will give you a more accurate reading of your coolant level than the dipstick method. To use a hydrometer, simply float it in a sample of your coolant and read the number that lines up with the liquid surface.

If your coolant level is low, add more until it reaches the “full” line on your dipstick or floats at 1.060 on your hydrometer.
