Clean any coolant residue with a rag to better see the leak source.

3. Repair or Replace Components

If the coolant reservoir is damaged:
1. Remove the coolant reservoir by disconnecting the hoses and mounting bolts.
2. Replace with a new reservoir, ensuring all connections are secure.
If hoses are damaged:
1. Loosen and remove the damaged hose clamps.
2. Replace with new hoses, ensuring proper routing and secure clamp attachment.
If the radiator is leaking:
1. Drain the coolant from the radiator.
2. Remove the fan shroud and any attached components.
3. Unscrew and detach the radiator from its mounts.
4. Install a new radiator, following the reverse order of disassembly.
If the water pump is leaking:
1. Remove the drive belt by loosening the tensioner.
2. Remove the water pump bolts and detach the pump.
3. Clean the mounting surface and install a new water pump with a new gasket.
If engine gaskets are leaking:
1. Identify which gasket is leaking (head gasket, intake manifold gasket, etc.).
2. Remove necessary components to access the gasket.
3. Replace the gasket and reassemble components, ensuring proper torque settings.

4. Refill Coolant

After repairs, refill the cooling system with the correct type of coolant as specified in the owner’s manual.
