The transmission cooler lines are located coming from the radiator on the bottom. One is for the sending and the other for return. The lines are high pressure, just as your radiator hoses are when the car is running. The lines go from the radiator to the top of the transmission.
Connected to the bottom of the radiator you will see 2 lines. One is the inlet and one is the outlet. The cooler line is the return (outlet) line.
I don't have a schematic for the radiator, but I believe the IN is the bottom hose on the radiator, and the OUT is the top.It really shouldn't matter because it is just a loop through the radiator.Take Care,Greg
Although I am not familiar with the vehicle in question specifically, generally the line that goes to the top side of the radiator is the supply, and the line from the bottom of the radiator or trans cooler is the one returning the fluid to the trans.
Pressure and return lines that goto radiator and or transmission cooler to keep the ATF chilled off.
You will notice two lines going to your radiator from the transmission. One is a service line and one is a return line. The radiator has a transmission cooler built into it. If you have trans fluid in the radiator chances are the trans cooler is leaking. A little trans fluid in the radiator will not affect engine cooling BUT as soon as the pressure drops in that transmission you may very well have radiator coolant sucked into the tranmission and that will ruin a transmission in a hurry. You need to get this checked out as soon as possible.
The hose that goes from the overflow to the bottom of the radiator on a 2002 Windstar is the bypass hose. It allows coolant from the overflow to return to the radiator as it cools.
There are 2 lines. The return line is the line that is the the coolest after running the car. Usually the top line.
Yes, pressure and return cooler lines.
It should not matter as one is pressure and the other is return from the transmission oil cooler.
Look in the yellow pages under "Transmission Parts". Go to them and buy the proper cooler. They will show you the proper way to install the cooler. Do NOT use an auto parts store. (The top line is from the trans. to the rad., the bottom line is the return. Fluid flows downward in the radiator.)
Remove the plug from the bottom of your 2000 Chevy transmission. Allow the transmission to completely drained out. Return the transmission plug to its original position. Fill the transmission with new fluid.
Return is the one that connects to the rear of the transmission.Return is the one that connects to the rear of the transmission.
touch it ,the cooler one is usually return
I know that the top radiator hose on my 4.0 liter OHV gets hot when the engine thermostat opens allowing the engine coolant to flow through the radiator and the bottom return hose connects the radiator to the water pump should be cooler - sounds normal to me but I'm not a mechanic / technician
that is the transmission return cooler line
Engines return hot coolant to the radiator through top hose, and cooled coolant goes back to the engine through the bottom hose, so a difference in temperature between the two would not be unusual. Assuming you have allowed the engine to come up to temperature and the bottom hose is stone cold, either the radiator or bottom hose is blocked, the water pump has failed or there is an air lock. A seized viscous coupling on a cooling fan or a permanently running electric fan can also make the radiator over-cool, but the bottom hose would feel slightly cooler than the top hose, not cold.
The top hose.
Why does the radiator fill up the reservoir
bottom left is the inlet, bottom right is the return, top goes to the engine, bottom is the breather
Under normal circumstances it will have some pressure just less than the bottom hose. The bottom hose is directly pressurized by the water pump while the upper hose acts as a return hose to keep the water flowing through the engine block. If there is no pressure you could be low on radiator fluid (water/anti freeze mixed) or have a thermostat stuck open.
I assume this readiator is in a non-turbo car. The fan units are attached to the radiator itself. Once you remove the whole radiator fans and all it will be much easier to work on. The radiator is held in place by two clamps at either top side of the unit. Remove feed and return hoses, and unplug two temp sensors at bottom of radiator. Remove trans cooler lines (if auto trans). The fan units are secured to the radiator by four screws.
one large hose from bottom of radiator to side of water pump. other large hose from thermostat housing to top of radiator. one heater hose from water pump to heater core, I think this one has a Y in it if there is a rear heater other heater hose from heater core to somewhere on top the engine. If there is a rear heater, its return hose goes to a fitting on the radiator.
