I have a water leak in the back of the engine fan

ok check these things #1 check for leaks at the radiator #2 water pump for leaks#3 check for freeze plug leak#4 check to see if your cooling fan works#5 check to make sure the water jug is not leaking#6 fill the radiator with water then start your engine and try to see if you can tell if the water flows,if its not flowing check the thermostat,now you can check the thermostat by putting it down in some boiling hot water if while in the hot water it contracts its ok but i would replace it because it is work to go back to do so,check your radiator cap also,now if the fans are the problem then you should change the coolant temp sensor for the fans ,now i hope after making these check you will be able to solve the problem

follow this steps and fix it. God bless you

1. Determine the Reason for Water Pump Failure
   • 1 Repair a water pump by checking your car for a failure in the bearings. You can test for bearing failure by seeing if there is any play in the shaft that is connected to the electrical fan blades, as well as the drive pulley to the pump itself.
     
   • 2 If you notice any free play in the shaft or the pulley, you will need to take the pump apart and replace the bearings.
     
   • 
     
     
   • 3 Determine if the water pump failure is due to a leak in the casing. Examine the water pump housing for leaking or water stains in the drainage hole next to the pulley.
     
   • 4 If water is dripping from this hole, then the seals inside the pump need to replaced in order to repair the pump.
     
   Remove the Water Pump for Repair
   • 5 Allow the engine to cool completely before removing any part of the cooling system. Never open a radiator cap or plug while the engine is still warm.
     
   • 6 Disconnect the car battery. This will prevent the electrical fan from turning on while you are under the hood.
     
   • 7 Drain the radiator of all fluid and disconnect the radiator hoses. Collect the fluid with a plastic container and keep it in a safe place until you are ready to put it back into the radiator.
     
   • 8 Remove the fan assembly. This will include the shroud, the fan and the fan belt. Disconnect the electrical leads for the fan.
     
   • 9 Remove the pulley for the fan belt as well in order to have access to the water pump.
     
   • 10 Use a socket set to remove the water pump from its engine mount.
     
   • 11 Open the housing for the water pump and replace the seals or bearing as necessary. Some auto parts stores carry repair kits that have both the seals and bearings for specific types of water pumps.
     
   • 12 Reassemble the cooling system by replacing the water pump, pulley, fan belt, fan assembly and radiator hoses. Refill the radiator with the fluid.
     
   • 13 Start the engine to see if the water pump repair was successful. Check for leaks before you take the car out on the road.
     

You have a couple of different problems here. You need to address the leak issue first. If you took it to a shop, go back and tell them to fix their work. Your radiator fan is another issue. Is this fan the big one you normally see on engines or are you talking about the auxiliary cooling fan that is mounted in its own assembly right behind the radiator? The auxiliary fan is controlled by a temperature sensor that your car's computer operates. For a better explanation, see the following link:

More than likely, the shop that did your work did something wrong and they are required to fix their screw up. At a minimum, they should warranty their work for at least 90 days.

Hello,

when the car overheats, is there still water in the radiator?

If there is water in the radiator and the car overheats, then it means there might be some dirt or blockage in the radiator or condenser.

When the car is on the motion, air passes through the front and assists the fan to cool the engine. There are situation whereby air doesn't have free flow because of blockage in the radiator and condenser. Dust and debris can cause blockage. If this be the case, have your radiator washed thoroughly and cleaned.

If there is no water in the radiator when the car overheats, then there is a probably a leakage from the water pump. Or maybe your fan isn't blowing properly. The fan might be blowing weak air.

The above are what could cause your engine to over heat.

So start the check from the radiator. Poor water into the radiator, wait for some minutes, look under the car and observe if water is going to leak. If there is a leak, it might be from the water pump or a leaking hose.

If water from radiator has no leak, have your radiator washed and clean the condenser has they might block air that is suppose to cool the engine.

Also, make sure your fan is blowing properly or well enough to cool the engine.

Make sure you have the above checked thoroughly as they are the major causes of problems like this.

This overheating problem could lead to a burnt gasket and this can dry the engine oil which will eventually knock the engine. So have this problem fixed to prevent further damage that will cost you more money.

Lastly, remove the hose that connects the radiator to the engine, water from the engine will come out. Pour water into the radiator, the water will flow through the hose down to the ground. Do this severally. Now connect the hose back to the engine, pour water into the radiator. Start the engine, the water in the radiator will reduce, add more water till radiator is full.

In summary, the major cause of over heating problem is from the radiator, fan, water pump, blockage in the hose, and dirt in in/on the condenser. These are area you need to concentrate on.

I forgot to mention that the acceleration meter or engine meter on the dash board shouldn't be more the 5. It should be below 5. If it is above 5, it can cause overheating. I hope you understand what I mean.....

Regards.

The fan running is normal. you need to find where the coolant is leaking. If there are no visable leaks. then suspect the radiator/reservoir cap.

replace your radiator cap.

The leak can be coming from anywhere there is coolant in the system. the most common place for a leak on those engines is the water pump, Fallowed by the heater by pass hose. Sometimes the hose falls out of its holder and the fan rubs a hole in it.
You will need to find the leak and report back so we can try and assist you on the repair.
