Hi there,

Thank you for the donation.

There is a good chance that you have a coolant leak, it may only be Small but enough to cause some concern, I would get the cooling system pressure tested hot with the heater on, this will locate any minor external leaks, also make sure that the pressure cap is checked as well, start here.

Check oil
Check and suspect headgasket

There's really only one way to know for sure what's going on and that is to perform a leak down test. That will answer all your questions. Let me know what happens. Jeff

I think you are looking at the upper radiator hose and is all as one piece

Hello and thanks for donating

Make sure that the engine has not been running for awhile, and is cool. If the engine has been running the fluid will be very hot and under extreme pressure, and could injure you when you open the radiator cap.
Find the drain valve on the radiator to drain it. The drain valve should be on the bottom of the radiator. Drain the fluid into a bucket, do not allow it to run onto the ground. Once you have drained the radiator completely, close the drain valve.
You are now ready to install a back flush kit. These kits are relatively inexpensive and can be purchased at your local auto parts store. Follow the instructions on the back of your particular kit. In summary, you will have to cut the heater inlet hose going to the top of the engine. That is where you will install the T section provided in the kit into the coolant line. Slip both ends of the hose onto this fitting and tighten the clamps that came with the kit. Now, you can connect your garden hose to this fitting.
Place the diverter that came with the kit into the opening on the top of the radiator. This is where the water and coolant will pour out from when begin flushing the coolant system. A hose or tube will be useful to direct the water into a bucket.
Start the engine, turn the heater on high and turn on the garden hose. The coolant should begin circulating through the engine and coming out through the diverter on the top of the radiator. Continue this process until clean water begins to come out the top. This should only take several minutes.
Turn off the engine and garden hose. Next, drain the radiator again into a bucket and close the drain valve when you are done.
Now it is time to add the new anti freeze. Pour the entire contents of the anti freeze bottle into the empty radiator and fill it until coolant pours out of the neck. Screw the radiator cap back on and the job is complete. Don't forget to screw the cap back on for the T fitting you installed also.
Take a quick test drive to ensure that everything is working properly.

Coolant system flush seems in order also may consider a thermostat. Check that cooling fans are operating.

IF the fins are plugged on the radiator or the flow is restricted in the radiator, a pressure test would show nothing other than a leak.

Its an indication of low coolant check coolant and add as needed
do a coolant system pressure test and also would check headgasket
too

Its an upper radiator hose
