How to Drain Cooling System Dodge Ram (2005-2006)

  • The following instructions outline the proper procedures for draining the coolant system in 2005 and 2006 Dodge Ram gas engines. It is important to follow these instructions carefully to ensure the safety of yourself and your vehicle.

Draining a vehicle's cooling system refers to the process of removing the coolant, a liquid mixture used to regulate the temperature of the engine, from the system. This is typically done as part of routine maintenance in order to replace old or contaminated coolant with fresh, clean fluid. Draining the cooling system involves opening a valve or hose to allow the coolant to flow out of the system, and can typically be done by a mechanic or a knowledgeable car owner with the right tools and equipment. It is important to follow proper procedures when draining a cooling system, as the coolant can be hot and under pressure, posing a risk of burns if handled improperly.

Draining cooling system

Draining the coolant system in a Dodge Ram is an important part of routine maintenance that can help extend the life of your engine and improve its overall performance. However, it's important to follow the proper procedures to ensure the safety of yourself and your vehicle. Here's a step-by-step guide on how to drain the coolant system in your Dodge Ram:

  1. First and foremost, it's important to note that you should never remove the cylinder block drain plugs or loosen the radiator draincock while the system is hot and under pressure. This can cause serious burns from the coolant, so make sure to allow the system to cool down before attempting to drain it.
  2. Once the system has cooled down, attach one end of a hose to the draincock. Place the other end of the hose into a clean container.
  3. Do not remove the radiator cap when draining the coolant from the reservoir/overflow tank. Instead, simply open the radiator draincock and allow the tank to empty. Once the tank is empty, you can remove the radiator cap and continue draining the cooling system.
  4. If you need to drain the entire engine, you'll need to remove the cylinder block drain plugs. To do this, you'll need a socket wrench and a set of sockets in the appropriate size. Once the plugs are removed, the coolant will drain out of the engine.

The draincock on a Dodge Ram is typically located near the bottom of the radiator. It is a small valve that allows you to drain the coolant from the radiator and the cooling system. It is usually located on the driver's side of the vehicle, and can usually be accessed by removing a small plastic cap or plug. If you are having trouble finding the draincock, consult the owner's manual or a mechanic for assistance.

Refilling cooling system

When it's time to refill the cooling system, it's important to use the appropriate fluid to ensure the proper corrosion protection for the aluminum components in your engine. The recommended coolant is a mixture of 50% distilled water and 50% antifreeze, which will offer the best engine cooling without corrosion and a freeze point of -37°C (-35°F). If the coolant becomes contaminated or loses its color, it's important to drain, flush, and replace it with a fresh, properly mixed solution.

To refill the cooling system, follow these steps:

  1. Install the cylinder block drain plugs, coating the threads with Mopar Thread Sealant with Teflon.
  2. Close the radiator petcock.
  3. Fill the cooling system with the antifreeze mixture.
  4. Fill the coolant reserve/overflow tank to the MAX mark on the bottle.
  5. Start and operate the engine until the thermostat opens (the upper radiator hose will be warm to the touch).
  6. If necessary, add more antifreeze mixture to the coolant reserve/overflow tank to maintain the coolant level between the MAX and MIN marks. The level in the reserve/overflow tank may drop below the MIN mark after a few warm-up and cool-down cycles.

By following these steps, you can safely drain and refill the coolant system in your Dodge Ram, ensuring that your engine stays running smoothly and efficiently.
