1 make sure you have the correct radiator for your car.

What probably is going on is that the radiator manufacturer just make a radiator for your vehecle that also covers the vehicles with an oil cooler. If you look carefully at the left and right holes you should notice that they are different sizes. The bigger holes are for the oil cooler which yours doesn't sound like it was equipped with that option.

If it is the correct radiator there is no problem leaving the holes you don't use open. Or if they came with plastic plugs just leave the plugs in the unused holes.

Need to replace the transmission cooling lines from radiator to transmission. Are the ends just screwed into the radiator or are they pressed


they are a type of quick connect fitting. There is a special tool just for these types of fittings. If you remove the plastic cover that goes over the fitting you will see a metal clip in a groove. You can use a small pick to carefully remove the clip (they go flyin and get lost easily but they are available from your local GM dealer or parts store). Once the clip is removed you will be able to pull the line out of the radiator/transmission fitting.

Reinstall the clip after you remove the line. The new line will slide in and click into place.

Removal and replace radiator on 1990 ford taurus V6 3.8L w/AC


  • Remove the pressure cap. Place it aside for the new radiator.

  • Drain the coolant into a drain pan. The drain valve is located at the bottom of the radiator. Twist it counterclockwise until the fluid starts to drain. Close the valve when the coolant stops draining.

  • Locate the transmission lines at the bottom of the radiator. Ensure you mark both of the lines so you will know which one goes where. Unscrew these with a line wrench. Plug the line with a towel to prevent the transmission fluid from leaking out.

  • Unscrew the radiator hoses at the top and bottom of the radiator. The hoses are held on by hose clamps that can be loosened with a flat head screwdriver. Slide the hoses off the radiator with your fingers after the hose clamp is loosened.

  • Pry the overflow hose off with your fingers. The hose slides over a tube at the neck of the radiator.

  • Unscrew the mounting bolts at the base of the radiator. There will be one bolt on each side which can be unbolted with a socket wrench.

  • Unsnap any sensors connected to the radiator. They will have quick connect fittings that can be undone by separating the tabs and pulling apart.

  • Unscrew the fan shroud with a socket wrench. The fan shroud will slide off the top of the radiator. You can also remove the cooling fan as it is held onto the fan clutch by four small bolts. You will need a socket wrench to remove.

  • Lift the radiator out from the hood. You may need assistance as the radiator can be heavy and awkward to lift.

    How to remove radiator fan?


    Hi. Here's the procedure if you are going to replace the radiator fan.

    Things You'll Need:
    • New radiator
    • Container for old coolant
    • Set of socket wrenches
    • Ford disconnect tools or crescent wrenches
    • Flush treatment
    • Coolant
  • 1 Disconnect the negative battery terminal to prevent damage to any electrical parts. Open the drain **** on the lower rear of the radiator, remove the radiator cap and drain the coolant into an empty container. Remove the overflow tube from the radiator and the coolant recovery bottle.
  • 2 Unbolt the shroud with a 10 mm socket wrench and position it over the fan, out of the way. For a 5.0 liter engine on a 1991 through 2001 Explorer, also disconnect the electric fan wires and remove the radiator shroud. For a 4.6 liter SOHC engine, remove the A/C tubing from the retainer clips on top of the radiator.
  • 3 Use a Ford model specific disconnect tool to remove the transmission coolant lines on an automatic transmission. You can use two crescent wrenches as a substitute for the disconnect tool, just be careful not to twist the lines.
  • 4 Remove the four bolts holding the radiator in place with a 10 mm socket wrench. Place a piece of cardboard on the side of the radiator facing the engine as you remove it, to prevent damage to any engine components.
  • 5 Crawl under your Explorer and take the cooling fan out for 2002 and newer models. Again, you need some Ford specific disconnect tools to do this. Remove the fan bolts as well as the shroud, followed by the 4 radiator push pins. Also remove the A/C condenser brackets near the rear of the radiator, and wire the A/C condenser in place to keep it from getting damaged.
  • 6 Remove the radiator from the engine compartment. Models made between 1991 and 2001 will let you lift the radiator out by itself. For a 2002 or newer model, pull the radiator up, rest it on the wall of the engine compartment, and separate the A/C condenser from the radiator.
  • 7 Install the new radiator in the engine compartment. Once you have it resting in place, reattach all components in reverse order. Use a flush treatment, then replace the coolant. Turn the car on and let the car idle, with the heater on and the radiator cap removed, until it reaches normal operating temperature. Top off your coolant as needed.

    Radiator replacement


    Start by removing the shroud over the radiator area. There should be little plastic screws in it holding it on. Then drain the coolant from the old radiator. there should be a drain on the lower passenger side of the radiator facing the rear. looks like a white nut, turn that until fluid runs out. Make sure you have something available to catch the coolant. I used a small rubber hose attached to the end of drain to direct it to container. After all fluid has drained, disconnect the overflow hose running to the plastic bottle on right of radiator. Remove the 3 bolts holding the bottle in place, and remove. You will not have to remove fan and shroud from vehicle if you just remove the four bolts holding the blade itself to the pulley you can then slide them back far enough away from radiator to get it out. That will make things much easier. there are two other hoses that attach to the radiator 1 on upper passanger side and 1 on lower driver side, remove those. Then remove the two transmission cooling lines from the radiator and plug the ends to prevent dirt getting in. Once all hoses and lines are detached from radiator remove the two mounting bolts at top of the radiator where it attaches. Those are the only bolts holding it in. it rest inside grooves at bottom so you just pull up the radiator and you have it removed. Installation is the opposite of removal. Try to get your plastic (degas) bottle as clean as you can if your reusing . If radiator will not drain through plug for whatever reason, removing the lower driver side hose will drain very quickly but be ready for a rush of coolant. I hope this helps you out.

    WARINING
    Do not remove the cylinder block drain plugs or loosen the radiator drain **** with the system hot and under pressure. Serious burns from coolant can occur.

    WARNING When removing the radiator or A/C condenser for any reason, note the location of all radiator- to-body and radiator-to-A/C condenser rubber air seals. These are used at the top, bottom and sides of the radiator and A/C condenser. To prevent overheating, these seals must be installed to their original positions.

    Removal & Installation:
    1. Disconnect battery negative cable.
    2. Remove radiator pressure cap.

    Transmission fluid dripping out of bottom center of radiator, how do i remove the radiator. 1999 chevy venture


    Before you remove the radiator, check the transmission line connection's at the passenger side. There should be two, one at the top ( in ) and the bottom ( out ). There are only in place by a quick release and see if which line is leaking and replace the line or the O ring that seals the line to the radiator. Good luck and hope this helps. The transmission cooler only runs down the ends of the radiator. Good luck and hope this helps. Keep me posted, be glad to help.
