Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
This may be an involved job as there can be extensive corrosion with the cooling system in your vehicle. Removing the lower hose may show that the lower intake pipe has rotted. The first thing that should be done is to get the vehicle up in the air safely so that the exact source of the leak can be determined.
Here is a diagram of the lower hose assembly so that you can see the components involved
Let me know what I can do to help you with this
First start with a strong flashlight and pressurize the cooling system so that the leak becomes evident. Once you can tell me the source of the leak I can help you with the removal of parts to replace the leaking component
It is leaking from the lower end of the upper radiator hose at of hose that connects to the thermostat component. It appears to be the thermostat component.
It is raining here, and weather person said it will continue on and off until around the kick of MSU and MICHIGAN STATE game on Sat. It is going to be Sat afternoon before we can work on the car due the rain. The car is outside. We will get back on it Sat.
I see it is the UPPER hose that needs to be replaced. Depending on the area of the leak the air intake plenum and the intake will have to be removed to replace the thermostat housing (if that is where the leak is)
REMOVE OR DISCONNECT
Once you have all that off you can get to the thermostat housing
When you get around to finding the leak let me know if it seems to be in a different place
