Antifreeze and Engine Coolant
All internal combustion engines generate heat. To regulate the temperature of the engine, an engine cooling system, usually a water-cooled system, removes the heat. Antifreeze liquid solutions are added to prevent ice build-up in these systems at cooler temperatures.

What type of Antifreeze do you need for a 2006 Ford Fussion?
According to the 2006 Ford Fusion Owner Guide ( for North America )
It came from the factory with a 50 / 50 mix of distilled water and YELLOW
colored antifreeze ( meeting Ford specification WSS-M97B51-A1 ) in the
engine cooling system
What would cause the engine not to reach normal operating temperature?
but only temporarily.
A thermostat functions to regulate the flow of water between the engine and radiator.
On an average outside temperature day (75 degrees), "no thermostat" would result in (1) the engine not reaching operating temperature in the normal engine warm up cycle time and (2) much later in the cycle the engine would overheat caused by the water not remaining in the radiator long enough to cool down. More extreme outside temperatures would impact the previous results.
No thermostat or a defective thermostat that is stuck open. Also could be a deffective coolant temprature sensor. Or air bubble aroune the sensor on some cars.
What does it mean when transmission fluid leaks from holes in the block of a 1972 Dodge Power Wagon?
I am having the same problem with my transmission. What holes are you talking about and where are they located? Mine leaks all the time, I have tried new gaskets and sealants but it still leaks. It runs great, but I have to keep the oil topped off every couple of weeks. I think it is a A727 tranny. Very tough.
What might be the problem if there is ice under the radiator cap and the motor is overheating?
It sounds like the antifreeze / distilled water mixture is freezing because
the antifreeze mixture is too weak for the outside temperature
Usually the antifreeze and preferably distilled water mixture is 50 / 50
( Ford states to not exceed 60 % antifreeze )
Why would a car be over heating?
Hey.
The reason why your engine is over heating is 1.),Your engine has dirt and other gunk in it, or,2.)You need a new filter, or3.), your engine doesn't have a filter and you need to get one. The filter I recommend is the filter with the orange micro-fibers in it. I do not remember the name of it offhand, so I'll try to get back and tell you.

have the engine timing checked. if the timing is wrong the engine will overheat, are you loosing coolant?is the fan working, is the water pump working?
How does engine coolant get into the combustion chamber?
A bad head gasket , a warped head usually from overheating , would
allow engine coolant into an engine cylinder
How do you know if it is a radiator leak?
For radiator leaks look for the following signs: The car will overheat Coolant level will frequently drop Pool of coolant or water under the car radiator Obvious leak noted from radiator on starting the car Faulty radiator cap causing the leak
How do you repair intake manifold leaks?
Replace the manifold gaskets.
Word to the Wise: It would help to know what caused the leak. Bolts not tightened in correct pattern or torque, or just old age? Also, if manifold is aluminum, don't gouge the gasket mounting surfaces, only smooth w/ the yellow fingers tool you can get from SnapOn, or use fine sandpaper and a sanding block. Don't polish the surfaces either, or the gasket will slip or blow out.
How do you diagnose over-heating problems on a Taurus - Sable?
Copied from the "Related Question" below, written by DustedDisgusted:
- Is the coolant at the proper levels?
Is the coolant 'fresh' - still has most of the original color (green, yellow)
Note: One symptom of a leaking head gasket is "milky" looking coolant ?
- Next, let the engine warm up, feel the top radiator house, if it's not hot/really warm...
* Thermostat may have stuck closed
* Cooling system blockage - flush it
* Water pump -
* Metal water pump impellers are prone to rusting away if the coolant hasn't been changed often enough.
* Plastic/nylon impellers tend to wear away, or even break (ala original Ford Contours)
- If that's ok, let the engine run and make sure the cooling fan comes on, if it doesn't, check: fan fuse; the temperature sender; or the fan may have failed.
Turn on the a/c and the fan should come on immediately (you could possibly have a bad pressure switch in the a/c system that would keep the fan from coming on, but that's unlikely)
- Next turn off the engine and feel the lower radiator hose, it should be very warm, if not you possible have a flow issue, either the water pump or a clogged radiator core.
The best way to check for lack of flow is to remove the radiator hoses and run water through it, comparing inlet volume/time to outlet volume/time.
- If these are all good, could be a head gasket.
One test is to get a smog test station to check for HC's (hydro-carbons) in the cooling system by removing some coolant and sticking the "sniffer" in the radiator neck while in manual gas reading mode. there should be no hc's present. any reading warrants removing the heads for further diagnosis.
Other ideas?
There are many possible causes for over heating.- Thermostat sticking closed.
- Low coolant level, causes are (coolant leak internally or externally, for internal leak check for antifreeze in the oil, it will be cloudy or look like a milkshake.
- Water pump failure.
- Blown head gasket,signs are ( oil in antifreeze, air bubbles in coolant recovery tank, caution hot coolant can spray out without warning)and or white smoke (steam) out the exhaust, and or low compression in one or more cylinders
- Engine cooling fan malfunction (manifests when vehicle at a stop and running)
- Plugged radiator (either internally or externally)
- Collapsed radiator hose
- Incorrect or seized radiator cap
Does the engine cooling fan come on at 230 degrees and turn off at 190 degrees? You could have a bad cooling fan, relay or sensor problem. If all of these check out you need to check for leaks and repair them. Also a stuck thermostat can be the bad apple.
There was a recall on this car for problems with the cooling system, so the first thing to do is check to see if the recall was performed. Also, there was a TSB, number 01-11-6 dated 06/11/01 addressing this problem. It involved, among a number of other things, replacing the water pump with a modified water pump. The new water pump is part number 1F1Z-8501-AA.In addition, I would replace the serpentine belt with Ford part number F7PZ-8620-AB since there was a problem with the serpentine belt slipping.
If, after all this is done and it still overheats, the freeze plugs may have to come
out to inspect the block water passages for obstructions.
Engine overheats when a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage.
First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system.
Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant.
If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.
After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on.
Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out.
Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transferring engine heat to the coolant. Remove it and have it 're-cored'.
One of these steps will solve the problem.
In addition to this comprehensive round-up, I would suggest that water pumps can fail without the bearings going out. The impeller can wear and/or break loose from the shaft.

You should service the cooling system. Flush the radiator, replace the thermostat, install a 50/50 mix of new coolant, bleed the system, verify that the cooling fan/fans are working properly.
Thermostat stuck closed or the water pump has plastic impeller that broke. When my 97 sable water pump failed as above, it would be okay idling, but overheat when revved up or driven any.
check the coolant temp sensor, and make sure the fans are going if they are electric.The thermostat could be the problem. If the thermostat is not functioning, which happened to me on a long distance trip, the temp gauge in the car will not show any increase in temp. Sooner or later, like when you stop at Burger King, you will notice your car is overheating, coolant is pouring out onto the pavement, you are astounded since your temp gauge shows the engine temp is normal. What happens when the thermostat malfunctions is that it won't open up, allowing the cooling fluid to enter the engine, thus causing overheating. Good news is the thermostat is a cheap part, you can get it replaced for an hour's work of a mechanic, or if you are handy, you can replace it yourself. Check the rubber hose that goes to the engine from the radiator to see if it needs to be replaced, replace it at the same time (replace it if its cracking or very old).In my case, I was in a location that I could not get a new thermostat, so the mechanic took out the faulty one, urging me to get a new one soon and have it installed. I did that, and all seems to be well. The deal is that the thermostat keeps the engine temp in synch with all the electronics. You can drive it without the thermostat for a while, which just means that the cooling fluid goes right into the engine immediately instead of being controlled by the little thermostat (basically a gate that opens when a certain temp is reached). However for optimum performance, you should have the thermostat on there. But in an emergency, ie no part available, you can run without it.
Check the cooling system. Does it have enough antifreeze? Is it leaking any? If so, check the hoses and radiator. If that's okay, it could very well be the thermostat. If it gets stuck closed no coolant gets circulates. It's an easy fix. Just don't buy one from an autoparts store... buy a motocraft (ford) part. The aftermarket ones don't really fit like they should.
Make certain that the water pump is working. Replace your thermostat, it's probably stuck closed. If you follow the upper radiator hose out of the radiator, it will end in the thermostat housing. Take it off and you will find the thermostat inside. Note the orientation of the thermostat before you take it out so you know which direction to put the new on in.-Jesse
If you did not mix the coolant with water for a 98 grand prix will if hurt the car?
Well, we didn't use the right mixture and now the "check coolant" light has been blinking off and on for the last year. I think we damaged the sensor because it is not running hot. The optimum blend for coolant is half distilled water and half coolant. Straight anti freeze does not cool as efficiently as a 50/50 mix. You did not damage the sensor. Sometimes the "Dexcool" (GM orange long life antifreeze) can "gum up" the sensor and cause false readings. The sensor is located on the passenger side of the radiator about 6 inches down from the top below a transmission cooler line. It is held in with a metal clip. Remove the battery to more easily access this sensor. Remove the clip and sensor -clean and replace. (I would sugggest lowering the coolant level before removing the sensor and be sure to bleed the system after replacing the sensor and coolant.) For more details on anti freeze check out the following website. http://www.phmeters.com/New_Folder/antifreeze_application_note.htm Hope this helps. "G"
I am Trying to bleed air out of a 2000 Chevy impala radiator?
This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.
2004 Jaguar x type coolant reservoir leaked all over the ground why?
Possibly one of the outlets is broken therefore leaking all over your engine.
Where is the drain plug located on a 1996 Monte Carlo?
There is only one drain plug and it's on the bottom of the oil pan, just like in every other car around the world.
It is an engine oil coolant hose. It runs to the oil cooler, which is a dual processing unit. Oil flows through one side, and antifreezeengine coolant flows through the other.. The hose you are talking about carried antifreeze to the cooler, and then to the engine.
My car has a 4" long hose 1/4" ID in that location and it is a drain for coolant leaks in
the heater core [like a tiny radiator].
Had the same problem wiht my cougar. in some cases it is a faulty sensor. The sensor is really easy to replace and only costs like 15 dollars from any ford dealership. Also you must fill the coolant past the recommended full mark. I replaced my sensor and still had problems, but when i filled the resivore up slightly past the "hot" fill mark i have never had problems wiht it since
ALSO WHEN THE ENGINE IS COLD THE COOLANT LEVEL IS ALWAYS LOWER THAN HOT. MIGHT WANT TO TAKE THE CAP OFF AND LOOK IN RADIATIOR WHILE COLD, MAY JUST BE A LITTLE LOW OF COOLANT. ANOTHER WORK AROUND WOULD BE TO UNPLUG WIRES TO SENSOR AND PUT A JUMPER WIRE BETWEEN THE TWO AND DISABLE THE PROBLEM.
If a water pump has gone bad will there be a horrible smell in the car?
is it damp under or near the dash ? if so its most likely your heater core cause it will cause a very bad smell that would be first thing I would check
Where could a leak be coming from the engine coolant?
If you can see no external leak, then suspect an internal leak as in a Blown Head Gasket. This is very serious and severe engine damage will occur if you continue to drive the car. Get this repaired ASAP, and stop driving the car.
You do not let us know if you see coolant on the ground or on the engine. It's hard to diagnose with out a little more info.
