What are the causes of coolant leakage in the Dodge Journey?
1 Answers
Coolant leakage in the Dodge Journey generally occurs due to the following reasons: 1. Hose rupture. 2. Engine oil emulsification. 3. Loose radiator cap. 4. Leaking rubber hose connections. 5. Cracked radiator cooling tubes. 6. Radiator damage. Solutions for coolant leakage are as follows: 1. Hose rupture: If the leak is a crack ≤1mm or hole ≤2mm while driving, add a bottle of radiator sealant into the coolant reservoir and run the engine. 2. Engine oil emulsification: Disassemble the engine to replace the cylinder head gasket. 3. Radiator damage: (1) Add radiator sealant and run the engine. (2) After opening the cooling system's circulation for 5-10 minutes, all leaks (including coolant/antifreeze) from hoses, gaskets or the radiator will stop without requiring drainage, and won't affect cooling or cause clogging. (3) If no sealant is available, for minor leaks in cooling tubes, temporarily stuff tobacco strands into the radiator to utilize water pressure for plugging leaks. 4. Leaking cooling tubes: Cut the leaking section, plug it with soap-coated cotton, then crimp and flatten the tube end with pliers to stop leakage. 5. Leaking rubber hose connections: Tighten hose clamps with a screwdriver and pliers. For damaged hoses, temporarily seal cracks with adhesive tape. 6. Loose radiator cap: Securely fasten after inspection.
