▷▷ 2021 ▷ How to bleed the coolant system in a PT Cruiser ventos.site

Chrysler PT Cruisers are equipped with a coolant system bleed valve to help remove air from the coolant system after filling or draining and refilling the radiator. Air can be trapped within the engine’s water jacket, displacing the coolant and giving a false “Full” indication on the radiator and overflow reservoir. Removal of this air is important to maintain the total refrigerant capacity of the system and prevent overheating due to low refrigerant level.

Filling the cooling system

Step 1

Open the coolant system bleed valve located under the radiator pressure cap with a wrench.

Step 2

Install a 4-foot-long, 1/4-inch ID clear hose onto the bleed valve nipple. Route the hose down through the engine compartment and away from the radiator fan and accessory drive belts. Place the loose end of the hose in a clean container.

Step 3

Remove the pressure cap from the radiator. Install the fill aid funnel into the neck of the radiator pressure cap. Tighten the overflow hose with the attached clip.

Step 4

Slowly add a 50 percent mixture of coolant and distilled water to the larger section of the fill aid funnel until a steady stream of coolant comes out of the bleed valve. Tighten the bleed valve with a wrench and then remove the hose.

Step 5

Remove the clip from the overflow hose and remove the funnel from the neck of the pressure cap.

Step 6

Fill the radiator to the top of the neck of the pressure cap. Install the pressure cap.

Fill the coolant overflow bottle to the “Full Hot” mark.

Bleed the system

Step 1

Start the engine and allow the vehicle to reach maximum operating temperature.

Step 2

Stop the engine and allow it to cool completely.

Step 3

Check the coolant level in the overflow bottle and add coolant up to the “Full Hot” mark.

Perform steps 1 through 3 until the coolant level stabilizes at the “Full Hot” mark and it is not necessary to add more coolant. This can take three or four cycles.

Warnings

  • Make sure the engine is cool before removing the radiator pressure cap.
  • The use of propylene glycol-based coolants in your PT Cruiser is not recommended.
  • Swallowing or inhaling ethylene glycol-based refrigerants can be dangerous to your health. Seek immediate medical assistance in case of inhalation or ingestion of refrigerant.
  • Consult regulations for proper refrigerant disposal in your area.
