HMMM thinking out aloud here ,you sure its not condensation running down from the low pressure pipe on the AC ,,,, touch it with your finger and see if tastes sweet if so its antifreeze ,and the only cause of this that i think of is the shut off valve ,so when ac is on the valve closes and its leaking ,when ac is off the valve is open and its not leaking ,stop gap measure for rest of summer is to put two brake pipe clamps on the heater hoses

Over heating problems


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.

It is geting water inth air and ventilation system and throw it ina the cab


It's most likely a heater core leak. Hot radiator fluid is passed through the inside of the heater core, and air is passed over that. if there is a pin-hole leak in the radiator core, then it will come out of the vents. Turning off the heat setting will not change the leak either, it will still leak and collect in the lowest spot, and then blow out the vents when it strikes the fan impeller blades. the heater core is fed from 2 smaller radiator hoses. If you look under the hood, you'll see 2 large hoses that come out of the radiator. you'll also see 2 smaller hoses that go back towards the front of your car through the firewall. these 2 little hoses go to your heater core. Most cars require dash removal to change out the heater core. Unless you are pretty handy, I'd leave this one to the shop.

When i killed the car,it made a hissing sound.then my air conditioner quit working.what does it need?


Hi!!
Most likely, one of your A/C hoses is busted or there is a leak on the system. Follow the hoses coming from the compressor to the condenser (the coil in front of the radiator) and to the firewall, there should be oily residue where the leak is.
The repair should be made by a HVAC Technician.

Transmission fluid is leaking from the air conditioner condensor - however i am having trouble figuring out exactly where it is coming from (from a hose or from the condenser itself). The fluid has...


The transmission fluid is not coming out of your A/C Condenser for that only carries freon through it on the High side of your A/C System. I may be mistaken, but the condenser is mounted on the right front side (or passenger side) of your vehicle. Insofar as your transmission fluid leaking, there are two lines that go directly to your Radiator, either bolted straight in or at times, have a hose with clamps going down one of the tanks of the Radiator. Usually it's on the Driver's side front. This enables the transmission fluid to cool within the radiator before it returns to the transmission pan. It's a sealed "little radiator" within your Radiator, so if it's not leaking from one of the lines, then follow the lines (through the grille), and see if you have an "air-cooled" transmission cooler in front of the Radiator or Condenser. If your vehicle came with a Trailer Towing Package, then this "cooler" will be in front of the Radiator or Condenser at the lowest point. (it also goes through the radiator as I explained above). If the rubber lines are leaking, then it's pretty simple to replace, BUT you have to use Hoses that are meant for carrying oil or transmission fluid. "Normal" hoses will work for a while and then deteriorate causing the leaking problem again. The last thing to check is your transmission's dip-stick. Yes, if that's pulled up and not seated fully, one of your fans could be spraying the transmission fluid everywhere. Also note, that there's a "vent" in the transmission's dipstick that can be cleaned with compressed air. The purpose of the dipstick having a vent on it is to allow built up pressures to vent to atmosphere
(like your PCV system does for the Engine).

I hope somewhere above, you'll be able to find the solution to your problem.

Best of Luck,

  3. Remove or disconnect the following:
    Negative battery cable Coolant reservoir tank and bracket Upper mounting bracket Upper radiator hose Oil cooler lines, if equipped Lower radiator hose Cooling fan and condenser fan Fan motors and shields Radiator

To install:
  1. Install or connect the following:
    Radiator Fan motors and shields Cooling and condenser fans and torque the bolts to 44 inch lbs. (5 Nm) Lower radiator hose Oil cooler lines, if equipped Upper radiator hose Upper mounting bracket Coolant reservoir tank and bracket and torque the bolt to 44 inch lbs. (5 Nm) Negative battery cable
  2. Fill the cooling system to the proper level.
  3. Start the vehicle, check for leaks and repair if necessary.
WARNING Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

  4. Remove the radiator by performing the following:
    CAUTION Lifting A/C condenser should be minimum to prevent a load to A/C piping.
    With lifting and pulling radiator in a rear direction, disassemble lower mount from radiator core support center. Lift A/C condenser up and remove radiator after disengaging the fitting as front-bottom surface After removing radiator, put A/C condenser on radiator core support center to prevent a load to A/C piping, and temporarily fix it with rope or similar means

To install:
  1. To install, reverse removal procedure.
  2. Check radiator cap for any leaks.
  3. Start and warm up engine. Check for engine coolant leaks and A/T fluid leaks.

Hope this help (remember comment and rated this).
