Common Causes of Coolant Leaks in a 1997 Mercedes Benz C230

Faulty Coolant Expansion Tank: Check the coolant expansion tank for any cracks or leaks. If it is damaged, coolant can seep out.

Worn-Out Radiator Hoses: Over time, the radiator hoses can become brittle and develop leaks.

Defective Water Pump: A water pump that is not functioning properly can cause a coolant leak. Check for any signs of leakage around the water pump.

Cracked Cylinder Head: A cracked cylinder head can also lead to a coolant leak. It can occur due to overheating or age.

Loose Hose Clamps: Loose hose clamps can also cause coolant to leak. Check the hose clamps and make sure they are properly tightened.

Damaged Radiator: A damaged radiator can also cause a coolant leak. Check for any cracks or holes in the radiator and repair or replace it if necessary.

Faulty Thermostat Housing: A faulty thermostat housing can also lead to coolant leaks. Check the area around the thermostat housing for any signs of coolant seepage.

Old or Damaged Radiator Cap: A faulty or old radiator cap may not seal properly, allowing coolant to leak.

Always consult with a professional mechanic if you are unsure of the cause of the coolant leak.
