Disconnect the electrical at the top. Sometimes you can get the fan out and then the shroud-due to limited space. They would both come out from the top.
We mechanics will tell you to test the fan motor with jumper wires from the battery before you decide to pull it off. On most cars, the computer turns the fan on through a cooling fan relay. On your '87, it is possible that a thermal switch on the radiator may turn the fan relay on at a set temperature. One would have to see a wiring diagram.

Just looked at a diagram: If your car is fuel injected, check fuse #13, a 15 amp blue fuse. And same if carbureted, fuse #13-this fuse is for the relay and the fan motor. If carbureted, also check fuse #20-a 20amp fuse.
There are no computer controls for the fan on an '87. there is a thermo switch-at a set temperature, the switch will close-completing the ground path for the fan motor. There is also a radiator fan timer switch, tied in with the thermo switch and the air temperature sensor.
Sound complicated? Well, it is, even with no computer controls. If the fan motor is good, check or replace the thermo switch. Be sure and check those fuses, also. If no help, a tech will probably have to diagnose it.

Envoy cant get to water pump to change it. Removed grill exc but can't get radiator out and fan out

The fan and fan shroud need to be removed as one assembly. You will need a 34mm wrench to get the fan clutch removed from the water pump. Once the fan clutch is unthreaded and the bolts that hold the fan shroud to the radiator are removed you will be able to remove the fan clutch/ shroud assembly from the vehicle. You do not need to remove the radiator nor can you remove the radiator without first removing the clutch/shroud. You will notice that when you are removing it it will be a little tight getting around the inlet for the upper hose on the radiator . Once the shroud is removed trim a notch where the shroud was hitting on the inlet and I will make install a lot easier. If you have any questions let me know. Thank you for using!

Need location and r/r proceedure for fan blower motor on a 2001 grand cherokee limited.

backside of radiator you will see the fan shroud and fan assembly.
4 - 10mm bolts (one on each corner) will be holding it in place.
Remove the bolts (this will take some time as these bolts are in very tight areas) once the bolts are removed, very carefully pull the trans cooler line out of its mounting on the fan shroud (bottom drivers side of the shroud)
Pull fan and shroud out thru the top (be very careful wiggling it out, you do not want to break the shroud)
Once out, remove the fan motor (4 bolts and a round clip holding it in place)
Replace in reverse order.

Hope this helps

I want to know what the engine look likes with the radiaters and fans in it

I know that this may not be what you want, but it does cover how to remove the Engine Fans REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable.
  2. On some models, it may be necessary to disconnect the coolant hoses from the radiator to allow clearance for removing the fans. If so, drain the cooling system, then disconnect the hoses.
  3. Unplug the fan electrical connections.
  4. Remove the mounting bolts holding the fan shroud and remove the shroud with the fan. Once removed, the fan blade may be unbolted from the shaft and the fan motor removed from the shroud. Fig. 1: The fan shrouds are secured to the radiator with a series of small bolts 86803064.jpg
    Fig. 2: When removing the fan shroud, be careful not to damage the radiator cooling fins 86803065.jpg
    To install:
  5. Position the fan on the radiator and install the mounting bolts. Tighten them to 5 ft. lbs. (7 Nm).
  6. Engage the electrical connections.
  7. If applicable, refill the cooling system.
  8. Start the engine and allow it run until it reaches normal operating temperature. Check that the fan(s) turn on. Check for leaks.

These are very easy to do. 1. Spin the shroud of the fan about 1 1/2 " and the shroud will unclip and move forward over the fan. 2. remove the metal slide clips from the sides of the remainder of the shroud and lift up. 3.unscrew the 2 trans cooler lines from underneath and allow to drain in a pan 4. Remove the radiator hoses and allow to drain. 5, Remove the 2 metal clips on top and lift the radiator out. Be sure when you reinstall the shroud that you spin the fan and adjust the shroud accordingly so it does not hit. Let me know if you need anything else.

How to replace radiator in a 2002 jeep grand cherokee v8

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.
  3. For access to radiator draincock, remove radiator grill mounting screws and remove grill.
  4. Attach one end of a 24 inch long x 1 / 4 inch ID hose to the radiator petcock Put the other end into a clean container. Open petcock and drain radiator.
  5. Detach power steering fluid reservoir from fan shroud and lay aside.
  6. Disconnect electric cooling fan electrical connector, if equipped
  7. Disconnect CRS hose from radiator filler neck and remove from shroud retaining loops.
  8. Remove the four (4) viscous fan/drive assembly nuts from the water pump pulley and remove fan/drive assy.
  9. Remove the four (4) fan shroud to core support mounting screws.
  10. Remove the electric fan (if equipped) and shroud assembly from the vehicle
  11. Remove radiator upper crossmember.
  12. If equipped with air conditioning, separate radiator from condenser by removing condenser-to-radiator mounting brackets.
  13. Disconnect upper and lower radiator hoses.
  14. If equipped, disconnect and plug automatic transmission fluid cooler lines. Quick Connect Fitting Release Tool 6935 may be needed. If equipped with remote transmission cooler, remove line to cooler from bracket at bottom of radiator
  15. Lift radiator straight up and out of engine compartment taking care not to damage fins.
  16. If radiator is to be replaced, be sure to remove and transfer any components not included with replacement radiator.

To install:
  1. The radiator is supplied with two alignment dowels. They are located on the bottom tank and fit into rubber grommets in the radiator lower crossmember.
  2. Lower radiator into engine compartment. Position alignment dowels into rubber grommets in radiator lower crossmember.
  3. If equipped with air conditioning, attach condenser to radiator with mounting brackets
  4. Install radiator upper crossmember and four mounting bolts.
  5. Install radiator upper crossmember-to-isolator nuts. Tighten nuts to 86 inch lbs. (10 Nm) torque. If isolator-to-radiator nuts had been removed, tighten them to 47 inch lbs. (5 Nm).
  6. Connect radiator upper and lower hoses.
  7. If equipped, connect automatic transmission fluid cooler lines. If equipped with remote cooler, attach cooler line to bracket at bottom of radiator.
  8. Install electric fan (if equipped) and shroud assembly. Insert alignment tabs at bottom of fan shroud into slots in bracket at bottom of radiator. Tighten mounting bolts to 31 inch lbs. (3 Nm).
  9. Connect electric cooling fan electrical connector.
  10. Install power steering reservoir to fan shroud.
  11. Install grill.
  12. Connect battery negative cable.
  13. Fill cooling system with correct coolant.
  14. Install pressure cap.
  15. Check and adjust automatic transmission fluid level (if equipped)
  16. Start engine and visually check for leaks.

For more details I suggest review the Service Repair Manual:
- Section-07-Cooling-System-Ewj7 (page 33 and next)
- Section-07a-Cooling-System-Ewj7a

I really hope helped with this (remember rated and comment this help) Good luck.

Trying to replace the ac condenser fan on a 92 honda accord. How do you get to the bottom bolt??

You will have to remove the lower splash pan (plastic thing that goes across the entire front underneath, not hard to remove) from under the radiator in order to get at the lower fan bolts. The condenser fan shroud had a single lower retaining bolt; the radiator fan shroud has two.
Hope this is helpful.

Replace radiator

They are not to bad you just have to unbolt the top and the fans. It slots in the bottom no bolts but it can be a bit stubborn to get out some times. It is a tight tight fit to get them in and out just make sure you do not mess up the fins or put a hole in it putting it in
