HI. This issue has many causes. I will list the most common causes below.

Coolant consumption::: Possible causes______


1. Check the head gaskets. The gasket may be leaking.(Internal leakage)
2. Check The Intake Manifold Gasket. This gasket may be leaking, worn, or damaged
3. Check the cylinder head for worn or scorn cylinder block.(This will require total breakdown of the engine)


Now that we have covered the basic check points for coolant consumption, i would advise to concentrate on the head gaskets if there are no apparent leaks on or around the engine itself. If the head gaskets are worn, the leak can be introduced to the engine internally, causing the engine to burn off the coolant. this is noticeable by removing the oil cap, after a hard drive. you Will notice steam that will escape the head as soon as you remove the cap. If this is the case, your problem will be with a failed head gasket.

IN a severe case, you will notice white puffs of smoke escaping from the tail pipe during acceleration.

    • Additionally, you will notice a puff of white smoke at start up in the morning, or after a long shutdown period of the engine. This is a indicator of a failed head gasket allowing for the transfer of coolant into your cylinders.

    I have clearly described the only areas of concern in your case. This is an internal leak. Your head gasket will need to be replaced. I would inspect the other areas mentioned above for faults as well, but your symptoms are pointing to an internal crack in the head gasket area. This is introducing the coolant into the cylinder bock, which will cause the coolant to burn off.........

  • Michael Masters
    Michael Masters May 06, 2010

    OK, I have seen this many times before. What is happening is when the water or coolant has reached the internal crack in the gasket(head), it is forced to exit through this crack, and into the affected cylinder chamber. When this happens,the excessive coolant will be burned, during the combustion process, thus, producing the coolant consumption. In some cases I have seen, there will be no visible leaks or white smoke. At the rate you have described, this will most defiantly be a failed head gasket.




  • Michael Masters
    Michael Masters May 06, 2010

    NOTE_ There are only two areas on a standard engine that will consume coolant without apparent leakages. These areas are the head gasket(s), and the intake manifold gasket. In your case, the head gasket(s) will be the culprit.

  • Michael Masters

    I would not usually recommend to drive at that distance, considering the issues present with the engine. If this is your only option, carefully monitor the engine temp during the trip. As long as the engine temperature remains in a safe range, there should not be any problem with driving the vehicle to the nearest service depot.

  • Michael Masters
    Michael Masters May 06, 2010


    • The hesitation will be the result of a slight compression leak, due to the failed head gasket(s). This unbalanced compression ratio may induce "limp mode". This is a CUP induced mode that will cause the engine to preform at half mass to compensate for an obvious issue within the engine or CPU.


  • Michael Masters
    Michael Masters May 07, 2010

    The nearest service depot should have your gasket(s) in stock, or on SP status.

    (SP) = Special Order


    I would recommend to order directly from your local or nearest dealership service depot.

When this happens, that means the system wasn't truely full or has air. Usually a person can fill the coolant system once, then run the vehicle, all the coolant in the radiator will go into engine block. When the coolant is in the engine block, then the radiator is low or empty because the coolant is in the engine.
When filling a radiator or coolant system, it is best to do it with engine running and radiator cap off. You can also burp the top radiator hose while filling the system to remove the air and help push the coolant into the engine block so then you can fill the entire system. Engine block and coolant system both need to be full of coolant.

    50 % coolant 50% water all year round. Too much water will evaporate, too much antifreeze will not cool correctly.

  • Nate Stansfield
    Nate Stansfield May 06, 2010

    It is either evaporating, or your frost plugs are bad, or is draining out of your exhaust.
    I would also recommend getting a new radiator cap

    If it hesitates, you could have a gasket leak. Have you checked your compression in the cylinders to make sure there is no leak?

    If you do travel, test drive a smaller distance. Make sure you carry extra coolant. Double check head gasket and water pump to guarantee it is not leaking and make sure the temp gauge doesn't go into the red zone.
    If no leaks are preasant and temp is good, then you should be good to drive.

Replaced thermostat in my 2004 Chrysler Intrepid 3.5 - now coolant is running out. What could be the cause?


Coolant doesn't evaporate or get consumed. You have either an internal or external leak. If it's external, you should be able to see it. If it's internal, you might smell it in your exhaust or see it in your engine oil (foamy, looks like milkshake).

2006 Equinox. Losing water. Over heats. Is this a thermostat or water pump problem??


Depends on where the coolant is going.
If it is an external leak it could be a leaking water pump. If there are no external leaks and you are loosing coolant, it could be a blown head gasket. Especially if the engine has already overheated once.
A sticking thermostat would cause the engine to overheat and then loose coolant from the overflow tank. But not until it overheats.

Codes351/420/442/455 what do they mean


(M) Check Engine Light ("Malfunction Indicator Light" or "Check Engine") will illuminate during engine operation if this Diagnostic Trouble Code was recorded (depending if required by CARB and/or EPA). MIL is displayed as an engine icon on the instrument cluster.

P0351 (M)
Ignition Coil A Primary/Secondary Circuit
Peak primary circuit current not achieved with maximum dwell time.

P0420 (M)
Catalyst System Efficiency Below Threshold (Bank 1)
Catalyst 1/1 efficiency below required level.

P0442 (M)
Evaporative Emission Control System Leak Detected (medium leak)
A 0.040 leak has been detected in the evaporative system. (A faulty gas cap may cause this code). Also see TSB 25-001-02A. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system.

P0455 (M)
Evaporative Emission Control System Leak Detected (large leak)
A large leak has been detected in the evaporative system. See TSB 25-001-02. Also, possible faulty or loose gas cap. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection.

Have a bad oil leak from back of the motor


Check the rear main seal, if its coming out between engine and transmission it is time to replace. Usually this seal wont stop leaking even with seal conditioner. Depending on engine and chassis either the trans or motor will have to come out in order to replace the seal. If the seal is external than remove the trans, if a 1 piece internal than engine has to come out. Any way you look at it is a time consuming and big job.

Have a coolant pressure test done to see if the leak is external--radiator-- welsh plugs --hoses water pump--- heater . Have compression test done to determine if there is a head gasket or cracked head problem. Check the colour of the engine oil and if it is grey or milky there may be a leak behind the water pump impellor allowing water into the sump

Water disappearing out of radiator or plastic water tank, in Nissan Primeria 2001


The first step would be to pressure check the cooling system. Do this with the engine cold, then with the engine running, then with the engine hot. If there is an external leak you should be able to find it.

BMW keeps running out of water in the rad Please Help


Hi:
You need to find out if your car is leaking water onto the ground or if it is consuming it internally.

Here is a suggestion: When your car engine is cool, top off the radiator. The next day, before you start it, make sure the radiator is still full, and check under the car for puddles to see if it has leaked. Next,find a dry patch of pavement and start the car and let it warm up. Observe if anything leaks to the ground . If so, you can try to safely see the general location of the leak,to help figure out the problem. Look over all hoses, the radiator, and the water pump area for signs of wetness. If nothing is noted, re check the radiator level after the car cools again. If it is consuming water internally, then you most likely have a head gasket problem.

I don't have the owner's manual. The reservoir says ''Engine Coolant'' and it is empty; engine overheating. Is there a special fluid to use or can I just use plain water? Thanks


U need to use 50/50 mixture of long life/extendedlife coolant availible from any automotive parts store for around $8 per gallon. but you must have a leak, check for coolant leaking when the car is running, don't overheat this engine or u will blow the cylinder head gasket, a $1000.00 repair.
