Motor stuck

Hello friends I have a jeep Ebro that has been an old van for 12 years, what happens is that I think it is stuck by disuse, it provides to start it with a new battery but the engine did not move anything, what I should do is turn the engine from the crankshaft pulley but I need a glass key of more than 36 may I drag with another vehicle, can I damage it? The engine has oil and everything but I don't know if it is sure.

Hello, if you put a long march you do not have to have any problem,

Hello Singa18.
You comment that this equipment is standing for several years, the safest thing is that the engine is stuck and it is likely that damage to rings or cylinders has been caused. Now you must prelude to the engine to avoid major damage when moving it, take out the balancing cover and give them a clean oil bath, take out the spark plugs and add some oil to the interior of each cylinder, then try to move the engine without the spark plugs placed with movement of va and see, that is to say back and forward and good luck.

Hello Singa18.
It doesn't matter if the engine is diesel or gasoline, the council remains valid in any case.
