You need to find out if the leak is internal or external to the engine. There is a tool called a Radiator pressure checker and it works similar to a bicycle pump. Special fittings replace the radiator cap and you observe the pressure rating of the system when you add pressure.

If the leak is significant this test will spill the antifreeze from the leak. In difficult cases, an additive leak detection chemical can be added to detect a leak with an UV light.

If not successful you will need to pressurize the system and observe for pressure drop. This would mean the leak is internal like a bad head gasket. At best, you can diagnose which side (bank) of the engine needs to have its head gasket replaced by removing the spark plugs and cranking the engine to spray out the antifreeze from the problem cylinder. Again, a chemical dye and UV light would be helpful.

99 dodge grand caravan se is over heating about every five miles. I have to continually put antifreeze in


If it is leaking out that fast is should be pretty easy to see where it is leaking from. Find the leak, repair the leak and your problem should be solved.

Overheating


Overheating can be "boiled" down to a few issues:
*blockage: Something is stopping or slowing the flow. Main suspect is the thermostat. It is designed to open and close at the proper temperature so as to keep the engine at the optimum temperature range. They have a tendency to lock closed and cause overheating. Sometimes it's random. The blockage may be something like sludge or rust in the radiator or gunk that someone put in that does not agree with it.

*coolant/water loss. A leak somewhere. Blown head gasket, cracked head/block, hose, etc.
*pressure loss. This happens when the water gets to boiling temperature but is kept under control by pressure (pressure resists heat) and then something such as the radiator cap releases the pressure and the temperature rises. The coolant will also leak out and then the overheating will be due coolant loss as well. This is especially true with the Cadillac Northstar. The head bolts allow the head to lift off the block, ever so slightly, and pressurize the coolant system with exhaust gases beyond radiator cap pressure limits. It's usually when you accelerate or put the engine under load such as going up hill.

^check for exhaust gases in the coolant. smell it or buy a kit to test.
^get a new thermostat, or, test the old one by boiling it in water on the stove; see if it opens. I always get the "failsafe" kind: fails in the open position.
^check for oil in the coolant or coolant in the oil: grey sludge.
^check for leaks on the ground.
^test the radiator cap. some part stores have a way to test them.
^check to see if it's made by Cadillac. look for the word Northstar. If so, hold on to your wallet. There's a whole new world of overheating adventures.

Loss of Power / Over Heating


eeek, sounds like a possible head gasket failure. Check your coolant and oil. If the coolant is low top it off, and if the oil is milky, you are getting coolant in your oil which is usually a bad head gasket.

Overheating


If it's overheating but not losing coolant,replace the thermostat.If it's overheating from loss of coolant,replace the radiator cap with one that is the proper pressure for that engine.Rigger says luck toya.

Coolant loss no leak


hi.

Check compression. If the leak is internal, then the most common cause is the head gasket. Water (or coolant) leaks internally through the worn head gasket reaching the cylinders where it gets vaporized. Symptoms are coolant fluid level going down, bad performance, loss of compression, overheating, white smoke because of vaporized coolant from exhaust, traces of fuel in coolant reservoir etc.

If head gasket is Ok and there is no overheating, then the leak is external. Check pump, radiator and coolant lines.

Regards.

Over heating


When your temperature gauge reaches "H' it may too late to prevent a major breakdown. Knowing the symptoms of an overheated car and how they occur may be the difference between being inconvenienced and incapacitated.
Identification:---Other than a low oil level or low oil pressure light, there is not a more significant part of a car's instrumentation than a rising temperature gauge or a glowing "Hot" light. These lights are really the only confirmation a driver has that his car is really overheating. It is the identification of the symptoms of an overheating car that enable the motorist to avert a badly damaged engine. Overheating is always a traumatic event for a car's engine, which makes the early identification of the symptom an important addition to the informed motorist's tool kit.
Stuck Thermostat:--The car's thermostat is a valve that controls coolant flow from the engine block to the radiator. When the engine is cold the thermostat remains closed so that the coolant can reach operating temperature quicker and also provide heat to the passenger's compartment. The thermostat has a spring on it that moves depending on coolant temperature causing the thermostat to open. Sometimes the thermostat fails to open thus restricting coolant flow to the radiator where it would be cooled down. This condition is often the cause of overheating. The symptoms of this cause would be a rising temperature gauge and possibly the loss of heat inside the car.
Restricted Radiator:---A car's radiator will have thousands of gallons of coolant passing through in its lifetime. Along with the coolant comes particulate matter in the form of corrosion breaking loose from various parts of the car's cooling system. These contaminates collect in the tubes of the radiator reducing its efficiency. Extensive "plugging" in the radiator will cause the car to overheat. The symptom of this condition would be a rising temperature gauge which goes up when you accelerate.
Coolant Loss:--A car's cooling system is a closed loop system. You are not supposed to lose coolant. Sufficient coolant loss will cause the engine to run hot because engine is heating less coolant to higher temperatures. The symptom of overheating induced by coolant loss would be a pool of coolant on the pavement when the leak is external. Steam under the hood as the lost coolant hits hot parts of the engine, or a rising temperature gauge in the case of a undetectable engine related leak. Of course, the gauge would also go up if the leaks were not detected. Deteriorated Water Pump:--Cars use a belt driven pump to push the water and coolant mixture through the cooling system. This part is called the water pump. Rarely the impeller that draws the coolant through the pump will rust away making it impossible to push any through the system. If this occurs the temperature gauge will climb and coolant will boil over in the radiator. Inoperable Fan:----Most cooling fans are electrically driven. Some are driven by fan belts. If a belt breaks or the electric supply to the fan is interrupted overheating may result. Electric fans are tuned on thermostatically when needed. When the car runs at idle for extended periods or the weather is extremely hot, a failed fan will cause overheating otherwise it serves as a standby assist to the rest of the cooling system. In stress conditions an inoperable fan will cause the temperature gauge to rise. This will help. Thanks please keep updated.please please do rate the solution positively .thank you for using fixya

Over heat


If the head gasket goes water is allowed to seep into the cylinders and then out of the exhaust.

Once the level has dropped enough the car overheats

Or the water is pressurised in the radiator from the compression of the engine and it is forced out of the overflow leading to coolant loss and overheating

Overheating


Hi,
Engine overheating? Check:
1. Coolant level at cold
2. Coolant leak check for loss of, during "not hot" running condition. (water pump, hoses)
If above is ok, I would replace the thermostat. It's inexpensive and easy enough to do.

Hope this helps... Good luck!
