    the fan is mounted on the back side of the clutch fan, thus removing the four bolts for the fan itself does not allow me the ability to remove the fan and then replace with the new one.

Fuel gauge does not show me the correct amount of fuel past 1/2 a tank. I checked fuses and they are good. What am I missing?

Remove the upper half of the fan shroud to access the radiator fan. The fan should be held on by 4 bolts to the clutch fan. Unbolt the fan from the clutch fan and remove the fan, when installing use a little lock tight to ensure the bolts don't come losses and put everything back on revers. Good luck and hope this helps.

    Sorry friend, the clutch fan can be unbolted from the water pump. same as before, remove the radiator fan shroud to access more room. Leave the serpentine belt on so the water pump pulley does not move, on the back side of the clutch fan. You will see the shaft that connects the water pump to the fan clutch, you need to loosen the shaft and unbolt it from the water pump fan clutch and fan as one unit. It's been a while since i did mine. I converted mine to an electric fan from a Montana, gave me 15 HP out of the engine. Good luck and keep me posted, be glad to help. Any question on improvements on the jimmy just ask, might of tried it.

I have replaced two radiators so far and every time the fan damage the radiator. when installing the new one there is a big space between the raditor and fan. What can be the problem


You may be missing some spacers and/or bolts to secure the fan properly. The fan could also be damaged. For example, the fins may be bent, the shaft is bent/misaligned, the fan blade assembly has seperated from the shaft, or the fan housing is bent or broken causing the blades to hit the radiator.

Check that the fan is working properly, whether it is electric or a belt driven fan. A car will overheat if the fan doesn't function as originally designed.

Changed the radiator but the car is still running hot


Some thing too check:
Make sure coolant level is up to line and clean (not dirty, do to clogged radiator, may need to be flushed or replaced).
Make sure air flow through the out side of radiator is clear (dirt, leaves, ect..) .
Make sure fan is working properly equip t (is not running too slow). Or Manual (belt driven) fan clutch is working properly, not loose or spinning too freely?
Check for broken or cracked fan blades itself.
Check radiator cap, (no gasket tears).
Could be thermostat going bad ?
Could be coolant temperature Relay or sensor/switch (from computer) going bad?
Check radiator hose(s) (too soft, may collapse)?
In some rare cases:
Timing could be off.
Could be water pump.
Could be blown head gasket(s).
Could have cracked head(s).
ECT..............Hope this was some help???

Is it difficult to change out the radiator fan, or bracket. I noticed when idling the fan turns on and a bad rattling noise is made and then stops when fan cut off.


It seems that the radiator fan is hitting against the frame and so there is noise and vibration when the fan comes on. Shut down engine and check on the blades, see if there was any damage that would have changed the alignment or postion of the fan. If so you will need to remove and reset the fan. If the bearings or blades are seen to be faulty , replace them before the radiator is damaged.

The 6 cylinder coupling uses 3 bolts to hold the fanblade on.
The 4 cylinder uses 4 bolts.
If you are using a 4 bolt coupling, you have the right one. Check
to see if you haven't maybe put the fanblade on back to front.
Hope this helps you
