This is normal. When the gauge moves, it is thermostat opening and closing. Open, the gauge goes down a bit, closed, it goes up.

Don't forget to check the cabling to the dashboard , if the dial is rapidly moving up and down I would suggest , bad signal/sensor , poor grounding , your gauge I'm assuming jumps from C to mid way and back while driving , if it's jumping to H , stop driving as this would not be, no pun intended , cool!!

    If this doesn't happen when not driving I would go with loose connector as the vibrations while driving are giving you the intermittent contact for signals

the open pipe that you took the hose off of is the thermostat housing, you will need to remove this to reveal the thermostat, make sure you use a new gasket with sealant when reinstalling thermostat housing to prevent leaks and dont over tighten the bolts,run both bolts down as far as you can before final tightning

You need a new heater core and/or thermostat and/or water pump, once you've determined you dont have a busted hose or radiator leak (unlikely because the car would overheat).

Engine s running very hot and rad fan comes on ry early

On a ten year old vehicle like that, I'd say that the coolant wasn't replaced frequently enough, and the thermostat has rusted shut. Begin by flushing the cooling system, replacing its contents with PROPER antifreeze, and replace the thermostat and radiator cap.

My 2004 ford freestar has no heat. how do I add antifreeze or check if it is the thermostat

When the engine is cool, take off the radiator cap and add fluid till full. Also add coolant to the overflow tank if needed
To check the thermostat, leave the radiator cap off, turn heater controls to high heat, and start the engine and run it till at operating temperature (this is to remove air from the system.) Coolant level should drop a bit when the thermostat opens, so you may need to add more. Replace rad. cap when engine is warmed up.
The only way the thermostat would cause no heat is if it were stuck open. So feel the upper radiator hose as the engine warms up. It will be cold or cool till engine starts to warm up-should take about 10-15 minutes, and then the thermostat should start opening, and the upper hose will start getting hot. If the engine takes a long time to warm up, like 30 minutes, the thermostat may be stuck open, needing replacement. If all seems good, check the actuator doors (temperature blend door) on the heater case. The doors have to open properly to let air from the blower motor to pass across the heater core, and then out the vents.
Good luck. If the coolant level was low, that was likely the problem.

Where is the thermostat for the 2007 freestar

Follow your top radiator hose to the engine, where it connects to the thermostat housing (unless your newew car has somehow a remote mounted thermostat). It has to be near the top radiator hose, so when opened, coolant enters hose and goes into radiator.

Hi have a 2004 freestar I changed radiator-, water pump , thermostat, engine coolant if I drive on flat street my van runs good temp is normal but if I go uphill the gauge goes up to almost red once I...

Sounds like a faulty temp guage/r a strange malfuntion in a sensor to me as well, only doing it when it going up hill really makes no sense for the way the cooling system works so I doubt that its actually running hot, which is likely why he asked about the gurgling noise, it would force water back into the resivoir if it was running hot assuming that the thermostatic radiator cap is working properly.

Engine on my 2004 ford freestar is trying to over heat when accelerate and cools goes down when I slow down, also heats up going up hills.

Physically look in the radiator under the cap when cool, for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.
Radiator fins dirty, clean with a strong stream of water, not high pressure water.
Radiator clogged, try backflushing it, or replace.
Thermostat stuck open or shut, replace it.
Water pump worn out, can no longer move enough coolant, replace it.
Fan shroud broken or missing....
Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.
Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.

Air dam under front bumper is gone, loose, or broken. It actually has a purpose other than scraping on the driveway or curbs. It forces air up into and thru the condenser and radiator. If it's loose, airflow can actually push it out of place making it useless or blocking the airflow. Along with that, there may also be a plastic piece attached to the bottom of, and wraps up behind the bumper. If it's loose, airflow can actually push it out of place blocking the airflow. Simply reattach it with 4 or 5 screws.

Also, if the vehicle has A/C and electric fans, one fan is dedicated to the A/C and should come on almost the instant the A/C is turned on. The engine fan will run even with the key off, that is normal. The system is trying to cool itself. Hope this helps.

How do i change the coolant/flush radiator in 2004 ford freestar

Open the petcock on the bottom of the radiator and allow the old coolant to drain.

Close the petcock.

To refill you will first fill the degas container to the cold fill range, leave the cap off the canister. Turn all of the heater controls to warm and turn fan to full. Idle the engine until the thermostat opens. Top off the coolant and put the cap back on. Idle at 3000 RPM for several seconds and then idle again for a minute or so. Check the level and then repeat this 4 times, or until heat is coming from the front and rear heat units.

If you want to flush the system you will have to remove the thermostat and hook up your flush system to the radiator hose at the thermostat housing. Follow the instructions on your flush system then put the thermostat back in. Follow the instructions above to refill.
