Oil pan removal for 1994 k1500 4WD

You may have to loosen the transmission also to get enough room to remove it without taking the motor out. Make sure your pan is not cracked first. Also be careful when lifting the motor as to not damage anything on top of the engine.

15. Remove oil pan and suction tube.
16. Remove the 2 bolts from the front of the engine block stiffener.
17. Remove the oil pan.
    

To remove the engine oil pan either the engine has to be lifted all the way off of the motor mounts and the oil pan should just clear the flex-plate and transmission, or the front axle dropped down out of the way, or the transmission and flex-plate will have to be removed.

Usually if the engine can be lifted enough to fit a piece of 2x4 wood between the motor mounts and the frame then the oil pan will usually just have enough clearance to be removed from the rear and the oil pan should just clear the transmission and the flex-plate. Also, be sure to check that the fan blade does not damage the fan shroud when lifting the engine.

Let me know if you require any further assistance.

First look under the motor, if there enough room from the oil pan and the cross subframe just removing oil will be fine, if there's not enough room you will have to undo the motor mount's and with an engine crane lift the engine so you will have enough room to remove the oil pan.There no need to remove engine out.

No, should have enough room to slide it out ,if not disconnect the engine mounts and jack up or lift up the engine just enough to slide the pan.

On most, you need to remove all bolts around the perimeter of the pan, (You may want to remove starter to get to fasteners there) then slide a paint scraper between the pan and block to break the seal. Generally there is enough room to get the pan out. If you need a bit more room, support the transmission with a jack (use a piece of plywood on top to avoid bending anything) remove both engine mount through bolts and raise engine slightly (not too much or you will break something)
