Coolant Leak Diagnosis Cost
A pressure check of the cooling system should be performed to determine where a coolant leak is originating. After repairs, the system should be pressure tested again to verify that the repair is successful.
When a coolant hose is found to be leaking due to age and/or condition, you should replace all of the coolant hoses in order to prevent failure.
After the cooling system has been serviced or repaired, it's important to verify that the system is not leaking, the radiator fans are operating properly, and all air bubbles and air pockets are bled from the cooling system.
If you have a problem with the coolant level dropping, but no signs of an external leak, the issue may be an internal engine leak. This type of leak may be due to a leaking intake manifold gasket, head gasket, or oil cooler. A shop will need to conduct various tests to find these types of leaks.
