I would definitely try that. Where is the hose located in the engine compartment? What size are all the hoses?

The hose is called the "water inlet hose"; and there are 2 different ones, depending on your engine size. You will probably not find this at an auto parts store, but, here are the 2 different part numbers, if you want to go to a dealer for the part:

1.6 Litre: 16322-15050 $54.04 US

1.8 Litre: 16332-16060 $44.87 US

This should solve your problem.

SOURCE: My radiator cap is leaking antifreeze. I noticed

Not being a smart-alec here but, remove your cap and look to see if there is any flat spots on the filler area. If not, you just need to replace the cap.

SOURCE: over heats no leaks replaced thermo,hoses clamps

The engine is kept cool by a liquid circulating through the engine to a radiator. In the radiator, the liquid is cooled by air passing through the radiator tubes. The coolant is circulated by a rotating water pump driven by the engine crankshaft. The complete engine cooling system consists of a radiator, recovery system, cooling fan, thermostat, water pump and serpentine belt.

Check the coolant level in the recovery bottle or surge tank, usually mounted on the inner fender. With the engine cold, the coolant level should be at the FULL COLD or between the FULL HOT and ADD level. With the engine at normal operating temperature, the coolant level should be at the FULL HOT or HOT mark. Only add coolant to the recovery bottle or surge tank as necessary to bring the system up to a proper level. On any vehicle that is not equipped with a coolant recovery bottle or surge tank, the level must be checked by removing the radiator cap. This should only be done when the cooling system has had time to sufficiently cool after the engine has been run. The coolant level should be within 2 in. (51mm) of the base of the radiator filler neck. If necessary, coolant can then be added directly to the radiator.

While you are checking the coolant level, check the radiator cap for a worn or cracked gasket. If the cap doesn't seal properly, fluid will be lost and the engine will overheat.

Worn caps should be replaced with a new one.

Periodically clean any debris; leaves, paper, insects, etc. from the radiator fins. Pick the large pieces off by hand. The smaller pieces can be washed away with water pressure from a hose.

Carefully straighten any bent radiator fins with a pair of needle nose pliers. Be careful, the fins are very soft. Don't wiggle the fins back and forth too much. Straighten them once and try not move them again. It is recommended that the radiator be cleaned and flushed of sludge and any rust build-up once a year. If this has not been administered within the stated time, this may be why your vehicle is overheating at this time. Have the Radiator flushed asap if this is the case.

Now, if the coolant level is proper and, the cap is in fair or good condition, i would advise to move in the direction of the cooling fans and sensors as well. These fans are vital to the cooling process as well. The cooling fans must cycle in intervals to keep the coolant cool during stop and go driving or, long idle. They are also very important during the operational period of the AC during travel as well. i recommend inspecting the cooling fans while the engine is running. they should cycle during the running period. if this is not the case, you will need to test the operational value of these devices. The test procedure follows below


1. If the fan doesn't operate, disconnect the fan and apply voltage across the fan terminals. If the fan still doesn't run, it needs a new motor.

2. If the fan runs, with the jumpers but not when connected, the fan relay is the most likely problem.

3. If fan operates but a high current draw is suspected continue with the following ammeter TESTING.

4. Disconnect the electrical connector from the cooling fan.

5. Using an ammeter and jumper wires, connect the fan motor in series with the battery and ammeter. With the fan running, check the ammeter reading, it should be 3.4-5.0 amps; if not, replace the motor.

6. Reconnect the fan's electrical connector. Start the engine, allow it to reach temperatures above 194°F and confirm that the fan runs. If the fan doesn't run, replace the temperature switch.

Ok, Now we will move on to the next possible issue. The water pump. ok, due to the fact that your pump is driven by the drive belt, you will need to start the engine and listen for bad bearing, using a mechanic's Stethoscope or rubber tubing.

* Place the stethoscope or hose on the bearing or pump shaft.
* If a louder than normal noise is heard, the bearing is defective.

Replace the pump in this case.

You will also notice leakage around the pump housing if the seal has failed as well. this will strain the impeller and, ruin the pump.

Now. the last area of concern will be the thermosta. this is the most common issue that will inflict overheating in many vehicles. The thermostat is used to control the flow of engine coolant. When the engine is cold, the thermostat is closed to prevent coolant from circulating through the engine. As the engine begins to warm up, the thermostat opens to allow the coolant to flow through the radiator and cool the engine to its normal operating temperature. Fuel economy and engine durability is increased when operated at normal operating temperature.

There are several ways to test the opening temperature of a thermostat.

One method does not require that the thermostat be removed from the engine.

* Remove the radiator pressure cap from a cool radiator and insert a thermometer into the coolant.
* Start the engine and let it warm up. Watch the thermometer and the surface of the coolant.
* When the coolant begins to flow, this indicates the thermostat has started to open.
* The reading on the thermometer indicates the opening temperature of the thermostat.
* If the engine is cold and coolant circulates, this indicates the thermostat is stuck open and must be replaced.

The other way to test a thermostat is to remove it.

* Suspend the thermostat completely submerged in a small container of water so it does not touch the bottom.
* Place a thermometer in the water so it does not touch the container and only measures water temperature.
* Heat the water.
* When the thermostat valve barely begins to open, read the thermometer. This is the opening temperature of this particular thermostat.
* If the valve stays open after the thermostat is removed from the water, the thermostat is defective and must be replaced.
* Several types of commercial testers are available. When using such a tester, be sure to follow the manufacturer's instructions.
* Markings on the thermostat normally indicate which end should face toward the radiator. Regardless of the markings, the sensored end must always be installed toward the engine.
* When replacing the thermostat, also replace the gasket that seals the thermostat in place and is positioned between the water outlet casting and the engine block.

* Generally, these gaskets are made of a composition fiber material and are die-cut to match the thermostat opening and mounting bolt configuration of the water outlet.
* Thermostat gaskets generally come with or without an adhesive backing. The adhesive backing of gaskets holds the thermostat securely centered in the mounting flange, leaving both hands of the technician free to align and bolt the thermostat securely in place.

How do i change the heater hoses

If they're not leaking you don't. If they leak at the plastic tee's, just cut the tee out. Go to the hardware store and buy a barbed tee, 5/8 or 3/4. and three hose clamps to fit. Why spend $50 for the hose, when can repair them for $10.

To see 100% what is going on the cooling system should have a pressure test.This involves putting the system under pressure using a pump with the engine cold.At this point it should become clear exactly where the system is leaking.The problem with trying to diagnose a hot engine is that the coolant will hit the hot engine and evaporate.This test will take all the guess work out of the situation and provide you with the information you need to determine on how to proceed. good luck

Cant bleed air out of cooling system way to actually bleed air out of a Taurus cooling system is to take loose the heater line returning
to the water pump, install a back-flushing tee in the hose, and start the engine while full of antifreeze.
Do this while engine is cool. While engine's warming up,loosen the cap on
the tee and let the air bleed out.KEEP the antifreeze away from the alternator and other components while you do this.
Of course,this will only work if you haven't got a BLOWN HEAD GASKET,letting compression seep into coolant.don-ohio .

I woke up this morning and my antifreeze had been leaking. I think it's leaking from the hose that connects the radiator to the engine. Is this a cheap fix to do on my own? Are there any other reasons it...

i would 1st check to see that the hose clamp was not loose, if so then tighten it with a screwdriver , or suitable tool. if hose has to be replaced , cooling sysytem will have to be drained down enough to allow the hose and clamp to be removed, without losing anti freze, then remove the hose and clamp then install the new hose, and clamp , and tighten down, re fill cooling system, and then start up vehicle and check for leaks, add aditional coolant if needed, then install radiator cap, then shut off engine, let engine cool, and later recheck coolant level. make sure engines cooling system has purged it self by getting the air out of the system , [ by running engine after you replace the parts, and etc, make sure you don't over heat the engine, it temperature gage riies, shut off engine, let it cool so engine can purge.

RAdior is leaking badly what do I do? One of the hoses seems to be broken, and seems like a huge leak on the bottom??? Need help asap contact me at

  • Turn off the engine as soon as you suspect a leak, to prevent the engine from overheating.
  • 2 Determine which radiator hose is leaking and exactly where the leak is coming from by looking for wetness.
  • 3 Purchase 1 gallon of antifreeze and the correct replacement radiator hose from your local auto-parts store or dealer. (Radiator hoses are not interchangeable. They come in specific sizes and shapes for your particular car model.)
  • 4 Wait for the engine to cool down for at least 20 minutes, before beginning any work on the cooling system.
  • 5 Place a large pan or wide bucket on the ground under the hose to catch the coolant.
  • 6 Use a screwdriver to loosen the hose clamps at both ends of the hose you are replacing.
  • 7 Remove the radiator hose by twisting and pulling where it connects to the radiator and engine. If the hose won't budge, use a utility knife to cut it off the fittings.
  • 8 Remove the hose clamps from the old radiator hose and slide them onto the new hose.
  • 9 Put the new radiator hose on. Spray the inside of the hose ends with WD-40 if the hose is hard to get on. Tighten the hose clamps.
  • 10 Refill the radiator and the coolant reservoir with a 50-50 mixture of water and antifreeze.
  • 11 "Burp the cooling system" by running the engine with the radiator cap off until the engine warms up. Keep the engine running until both the upper and lower radiator hoses feel warm (this indicates that the thermostat is open and the coolant is flowing through the entire system). Burping the cooling system allows any air bubbles to escape. Add coolant to the radiator as needed.
  • 12 Look for leaks. Inspect around the hose clamps for dampness. Tighten the hose clamps if there is any wetness.
  • 13 Put the radiator cap back on.
  • 14 Check the coolant level after driving, to ensure there are no leaks

    Leaking antifreeze from the back of the engine

    You have not indicated the year of your vehicle but if it is over 5 years old the likely cause is a leaking hose in the cooling system. The heater hoses and those pesky little bypass hoses in the cooling system tend to go hard and split if they are over 5 years old, allowing coolant loss. Check all the hoses and clamps where they connect to the various pipes in the engine bay and fix/replace any that are suspect. If they are all OK and not leaking then the cause could be a corroded expansion plug on the side of the engine block. This type of problem usually occurs in older (20Yrs +) engines that have had insufficient inhibitor/antifreeze over the life of the engine.

    I was driving a 1997 Buick Skylark Custom 3.1 less than 5K when white antifreeze smoke started filling inside the cabin of my car. It appeared to be coming from inside the dashboard and the windows were...

    The "smoke" you saw was your coolant. The vehicle uses engine coolant piped into the cabin of the car and through a little radiator under the dash for the heater. The blower in your car forces air over this radiator and this heated air is what you feel at the vents.
    If you're lucky then one of the hoses has sprung a leak. This is a relatively uncomplicated cheap fix. The other thing that could have happened is that the cabinheater radiator has sprung a leak. If the leak is serious then the heater radiator will need to come out for repair or replacement.
    You could try running some radiator stop leak(I've used Wynn's before) through the system and see if it helps. If the leak is on the radiator it might just work. On the pipes it will not be successful. Buy a bottle at your local spare shop/Autozone. Put it in the cooling system(do not open a cooling system with the vehicle hot!) and let the vehicle idle for a while. (Read instructions on the bottle) If it does not work, have the heater radiator removed and repaired.

    I think a hose is broken by the heating coil heating coil works

    Let the mechanic replace the hose T. It may be hard to spot the leak. What I would do is get a pressure tester and apply pressure to the system at the radiator cap (make sure its full of fluid) Then you should be able to easily identify where the leak is coming from. It will shoot out of the Tee most likely if thats where the crack is.
