My air conditioner quit blowing cool air. My 2006 Nissan Sentra is leaking coolant out of a skinny black hose near the front left of the engine by the air conditioner line. how can I stop up the hole?


Good idea is to drain the coolant from your radiator, then replace the hose that is leaking and then fill with coolant to the proper level. Drive your car and have heater running to remove any air in the system.

Could be air in cooling system. Check radiator cap on motor. Open when cool, fill to top and start car. Pump hoses to get air out. While running keep filling when thermostat opens. Rev engine if you'd like to quicken the process. When you can get anymore coolant it put top back on. Check for leaks!

My chrysler overheats i have to have heatr on full blast to keep it in normal operating temp........ i was told it was the radiator clogged i flushed it three times.. now the hat doesnt gt as hot and it...


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.

Have a 91 nissan pick-up staight 4 have it over heated oce replace thermostat and hose upper ran it for a day got hot again took out the thermostat and still gets hot what is the deal please help lee....


Replace the water pump, and also check for air in the system. Make sure the vehicle is cool, remove the radiator cap, start the vehicle and start pumping the lower radiator hose with your hand to help remove any air pockets in the cooling system. I would try this first before looking at the water pump or the fan since you let air into the system the minute that you removed the hose to install the thermostat and upper radiator hose

The a/c on my 2003 honda accord will all of a sudden stop blowing cold air. I already had the filter changed thinking that was the problem. The mechanic is having a hard time figuring out what is wrong...


have you tried refilling the aircon gas ?

It goes empty after a while.

The reason for cold then not cold is because it is a system that works in reverse of your radiator.

The gas cycle through the system. goes through the radiator of the the aircon system (not the same as the one for the engine). there is extracts the heat out of the air. the air is now cold and pushed into the car.

the warm aircon gas the made cold further along the system but the dont have enough in the system.

imagine athletic ruynning around a track. all 20 are bunched up together. there is w spot light in the centre of the infield shining on you.

the track is your aircon system.
the spot light the air coming into your car.
You are the car
The athletes are the aircon gas.

When they run between you and the light the air is cooled off and you are getting cold air.
now of goes the air (athletes) around the system and till they come along again you get hot air.

Now fill up the aircon system (put more runner on the track and voila, less light reached you cos there is more gas in the system.

However if you refill it and after a day or even just a week it the same again you have a leak in your system and will need to have it looked at by someone specializing in car aircon repairs.

How do you put in a radiator for a 1993 eagle talon? can i do it myself?


here you go, start with draining the radiator fluid there is a valve on the front drivers side at the bottom of the radiator. undo both radiator hose from the engine. next disconnect the radiator fans. there is 2 radiator suports on the front support bar they should be a 10mm socket.when just lift it right out. p.s. if its an automatic there is 2 cooling hoses for the transmission.

Replacing the radiator system for nissan altima 1998


Drain coolant from the cooling system. White plastic drain plug in bottom of radiator.

take off bottom rad. hose and top rad hose.

All wrenches and sockets are either 10 or 12 mm. Remove air shroud from around radiator and fan.
Sometimes its easier to remove fan too.

If its an automatic, remove 2 rubber hoses at bottom of rad.

remove 4 bolts top and bottom that hold rad. in place.

reverse order of parts. Fill with coolant and check for leaks.

That is the basics of it.
