Watch how to bleed coolant system on a 5.7L #hemi in a chrysler 300c with #moparbro fred_eazy21

This coolant bleed and fill procedure also applies for the 6.4L Hemi in Dodge Charger , Dodge Challenger , Dodge Magnum , Dodge ram & other SRT SRT8 mopars that have a hemi engine.


Bleeding the coolant system in a Chrysler 300C with a 5.7L HEMI engine is an essential maintenance task to ensure proper cooling system operation and prevent air pockets that can lead to overheating. Here's a step-by-step guide to bleeding the coolant system:

Park the Vehicle: Make sure the vehicle is parked on a level surface and the engine is cool to the touch before starting.

Open the Hood: Release the hood latch and raise the hood to access the engine compartment.

Locate the Coolant Reservoir: The coolant reservoir is typically a translucent plastic tank located near the radiator or firewall. It's usually labeled with "Coolant" or "Antifreeze" markings.

Check Coolant Level: Check the coolant level in the reservoir. If the level is low, add a 50/50 mixture of coolant and distilled water to bring it to the proper level. Use the recommended coolant type specified in the owner's manual.

Identify Bleeder Valve: Locate the bleeder valve on the coolant system. This valve is usually located near the highest point of the cooling system, often on or near the thermostat housing or radiator.

Prepare Tools: Depending on the design of the bleeder valve, you may need a wrench or socket to loosen it. Additionally, have a funnel and a container to catch any excess coolant.

Start the Engine: Start the engine and let it idle. Allow the engine to warm up to operating temperature while monitoring the temperature gauge.

Open the Bleeder Valve: Once the engine reaches operating temperature and the thermostat opens, locate the bleeder valve and carefully loosen it with the appropriate tool. Be cautious as hot coolant may spray out when opening the valve.

Bleed Air: As you loosen the bleeder valve, air bubbles and excess coolant may escape from the valve. Keep the valve open until a steady stream of coolant without air bubbles flows out.

Tighten the Valve: Once the coolant flows steadily from the bleeder valve without air bubbles, carefully tighten the valve to prevent leaks.

Check Coolant Level: After bleeding the air from the system, recheck the coolant level in the reservoir and add more coolant if necessary to bring it to the proper level.

Close the Hood: Once you've completed bleeding the coolant system and verified that the coolant level is correct, close the hood securely.

By following these steps, you can effectively bleed the coolant system in your Chrysler 300C with a 5.7L HEMI engine, ensuring proper cooling system operation and preventing potential overheating issues.
