By eHow Cars Editor Replacing a leaking radiator hose can be easy and quite painless on most cars. Check that both ends of the leaking hose are easily accessed before attempting this repair, because on some cars the hoses are tightly tucked away and this job might be better left to a professional. == == == == == == == == Difficulty: Challenging Step1 Turn off the engine as soon as you suspect a leak, to prevent the engine from overheating. Step2 Determine which radiator hose is leaking and exactly where the leak is coming from by looking for wetness. Step3 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.) Step4 Wait for the engine to cool down for at least 20 minutes, before beginning any work on the cooling system. Step5 Place a large pan or wide bucket on the ground under the hose to catch the coolant. Step6 Use a screwdriver to loosen the hose clamps at both ends of the hose you are replacing. Step7 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. Step8 Remove the hose clamps from the old radiator hose and slide them onto the new hose. Step9 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. Step10 Refill the radiator and the coolant reservoir with a 50-50 mixture of water and antifreeze. Step11 "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. Step12 Look for leaks. Inspect around the hose clamps for dampness. Tighten the hose clamps if there is any wetness. Step13 Put the radiator cap back on. Step14 Check the coolant level after driving, to ensure there are no leaks. · If the leak is coming from around the clamp holding on the hose end, tighten the clamp with a screwdriver. This may be all you need to do if a loose clamp is causing the leak. · In a pinch, you can add either plain water or pure antifreeze if that's all you have, but your cooling system normally uses a mixture of 1/2 antifreeze and 1/2 water. · Never open the radiator cap or loosen a radiator hose clamp when the engine is warm or hot. The coolant could spray out and burn you. · Dispose of used coolant properly. Bring it to a repair shop or parts store for recycling. Do not pour it down the sink or into the gutter.
The cooling system in the 198 Expedition includes the radiator and its reservoir along with the thermostat. This system included an oil cooler as well, depending on the model purchased.
If there are lines coming from the transmission to the radiator, it has a cooler in the radiator. If there are lines from the transmission to an external heat exchanger, that would be an auxiliary cooler.
If you can unbolt the cooler then unbolt it whatever way is easiest. Then remove the radiator. If it is part of the radiator itself then drain the radiator first completely and then disconnect the tranny lines and try to plug them if possible or put then draining into a container. Dont want to mix the fluids. Then remove the radiator. That should be it. That is way that I have done it before.
The main cooler is the passenger side radiator side tank. The optional cooler is an air cooler in front of the radiator.
You have a leaking transmission cooler, usually part of the radiator. The transmission fluid is mixing with the antifreeze turning it pink.
the cooler is part of the radiator.
There should be a Transmission cooler in the radiator, There might also be a 2nd one in front of the radiator!
drain radiator. remove upper and lower hoses from radiator. if automatic, disconnect tansmission cooler lines. remove fan shroud, or electric fan,whichever applies. unbolt radiator supports and remove radiator.
The automatic transmission oil cooler is built into the radiator. If the oil cooler developes a leak the oil mixes with the engine coolant.
If your vehicle has an engine oil cooler ther will be two hydraulic lines going to each side of your radiator. If there are only lines going to one side of your radiator, then it doesn't have an engine oil cooler.
Okay 2 types of oil cooling system fitted to these trucks. Light duty , and heavy duty. light duty, Oil cooler lines go from the oil filter housing to the radiator. oil cooler is built into the radiator. Heavy duty, Oil cooler lines go from the oil filter housing under the radiator and in front of the radiator there is a mini oil cooler.
Drain the radiator. Remove all of the hoses. Remove the transmission cooler lines if equipped with an automatic transmission. Remove the fan shroud. Remove the bolts that hold the top radiator support in place. Lift the radiator out.
It may be inside your radiator itself.
Failed transmission oil cooler, which is part of the radiator.Failed transmission oil cooler, which is part of the radiator.
A 1992 Honda Accord does not have an Engine oil cooler. It can have a transmission oil cooler, which is built into the radiator.
Yes it is in the radiator.
Transmission cooler is a separate tank area attached to the lower or side of radiator (one unit)
Yes. The engine oil cooler is in the drivers side tank and transmission oil cooler is in the passenger side tank of the radiator.
radiators are used as transmission coolers (typically) and only on automatic transmissions. you will have two metal oil cooler lines that go from the trans to one of the side tanks of the radiator. if you indeed have an engine oil cooler (on newer cars and trucks) you will have an add'tl two lines that go from the engine block (usually at a oil filter adapter housing) to the other radiator tank. if you have a standard trans and still have cooler lines going to the radiator its for engine oil. some but not many vehicles use the engine oil cooler as a total separate cooler usually mounted in various locations around the radiator and it will be smaller.
A transmission cooler is usually mounted just in front of the radiator.
An oil cooler works the same as a radiator that cools coolant
You have a failed radiator. Most vehicles have a trans cooler on the side of the radiator.
The tranny cooler inside the radiator went bad.
Disconnect battery cable, thendrainengine coolant,remove air cleaner,remove upper radiator hose from water bypass tube, remove radiator overflow hose from radiator and fan shroud. Noteloosen transfer. Oil cooler lines while securely holding radiator connector with a back up wrench, remove transfer. Oil cooler line from oil cooler inlet fitting, remover nuts retaining A/C csondensor core to the radiator,disconnect engine control sensor airing from the auxillary elect. Cooling fan motors and the CCRM, raise vehicle on hoist, remove splash sheild from lower radiator support and front sub frame, remove lower radiator hose from radiator. Note: loosen transfer. Oil cooler limes while securely holding radiator Conn. With a back up wrench, remove oil transfer. Cooler line from cooler outlet fitting on radiator, remove retaining screws for power steering/transaxle oil cooler and position cooler aside, support fan shroud, radiator and A/C condensor core with a suitable jackstand. Remove lower rediator support. Position jackstand aside and carefully remove radiator and fan shroud, remove two retaining bolts for fan Sheldon at top of radiator and remove fan shroud from radiator, remove upper radiator hose from radiator. Reverse to install.
The reason the fluid is a milky color is that water is getting into the transmission. How you ask??? Well the cooling lines go into the radiator to cool the fluid. It is at that spot it is picking up water as the cooler inside the radiator has a leak. the best solution would be to change the radiator. You could block the fitting ports for the lines at the radiator and put an external cooler on it. YOU MUST thoroughly flush the transmission and change the fluid and filter.
