Clutch does not release

Replace clutch,bearing and cover plate check fly wheel while assembly is off for wear and spigot bearing in center of fly wheel

The clutch is not fully disengaging. Adjust the clutch cable to obtain a 1/2 inch of free play at the top of pedal stroke. If clutch adjustment is not correct, damage to synchronizers or clutch release bearing will occur. Your clutch should begin to engage about an inch off the floor when releasing the clutch pedal.

check the clutch operation if it is hydraulic--press the pedal and see if the slave cylinder movers the throw out arm
It suggests a problem with the clutch master cylinder or a failed hose in the system that blocks off when the pressure is applied
hard to select the gears indicates that the pressure plate is not releasing
if it is a cable operation then replace the cable assembly as it is jamming up inside.

I just replaced my 2004 durango fan clutch and the new fan clutch will not disengage. The fan keeps runnning very loud i have replaced the new one already still doing the samething. Do i have a bad clutch or do i need to have the vehicle idle looked at

No leaks anywhere? It sounds like it is sucking air in the system.

Ive always checked the cluth by putting it in like 3rd gear and giving it a little gas before you release clucth pedal should almost want to stall but if it whinds up then you probably need clutch.

recheck the disc,it may be the wrong part,was the preasure plate also changed? check adjustments if any

"IF" you can pull the boot around the clutch release lever back enough. to shine a small flash light into the hole, Have someone shoot some P.B.Blaster(available at most hardware stores) "behind" the throw-out bearing and onto the splined shaft behind that. Avoid getting any spray on the clutch disk or the pressure plate work it back and forth. It might take a couple tries, but this should work.

Take it to another mechanic,Also check to see if it may be covered by a recall

when you say clucth is loose you probably mean that you have a lot of free play on the pedal..?

is it hydraulic?

if it is you'll have to bleed the clutch. if it isn't you'll have to adjust the clucth linkage.....
