1. Blown head gasket: A blown head gasket can cause the engine to vibrate and lose coolant. It can also lead to high pressure in the cooling system, which can cause the coolant to leak out.
2. Cracked cylinder head: A cracked cylinder head can also cause the same symptoms as a blown head gasket.
3. Faulty thermostat: A malfunctioning thermostat may lead to overheating and excessive coolant pressure, causing the coolant to leak.
4. Faulty radiator cap: A defective radiator cap can prevent proper pressure regulation, resulting in coolant leaks and engine overheating.
5. Water pump failure: A faulty water pump can disrupt the proper circulation of coolant, causing engine overheating and coolant loss.
6. Clogged coolant system: A clogged coolant system can restrict the flow of coolant, causing overheating and high pressure in the system.
To determine the exact cause of the issue, it's recommended to have the vehicle inspected by a qualified mechanic. They will be able to diagnose the root cause and provide the necessary repairs.
