As Pugo said leave the manifolds on untill the head is off Also on the 4x4 the temp gauge sensor is at the N/S rear of the head under the water hose so remember to take that off. (its quite hard to see) On rebuild just check, double check and check again your timing marks and make sure you are 100% happy with everything before you fire it up. Ive seen some messy engines due to lining that bottom pully up on the wrong mark

If in doubt ASK im sure anyone on here who has done it before will be only to pleased to help you out. Last thing anyone wants is another cossie off the road.
