  Q: How do you remove the cylinder head on 3.3L V6 Nissan Xterra?

  A:

  To begin with, you should release the pressure from the fuel system and remove the cylinder head. Following this, drain the coolant, and get rid of spark plug wires, distributor cap and spark plug wires as an assembly. After that, remove the intake manifold, camshaft sprocket, Timing Belt and rear timing belt cover. Then take away rocker arm components, lifters and exhaust manifold. Additionally disconnect hoses as well as electrical harness connectors including coolant pipes. Besides these, there is also need to remove air conditioning compressor, power steering pump and alternator. Also eliminate compressor bracket, power steering pump bracket together with alternator bracket. The distributor should be removed before releasing the cylinder head bolts finally. Be cautious when lifting off the cylinder head from the engine block in order not to spoil it! In order to install a new cylinder head; first of all remove old gaskets and make sure that both surfaces are thoroughly cleaned up using laquer thinner or acetone alongside a gasket scraper for that matter; if any damage is observed on them simply file or machine out if need be such as with damaged threads in cylinder head bolt holes that ought to be chased only after ensuring they are free of any dirt or grease therein before eventually placing new gaskets over dowel pins and carefully putting down heads on engine block; installation steps for intake manifold are completed by adding more fluids then oiling around threads for cylinder head bolts using recommended torque values in tightening them one at a time beginning from small bolt on outside section of its opposite side until drilling last hole followed by tightening bigger ones first prior to completing remaining installation steps in reverse order through addition of some coolants plus altering engine oil including filter alongside leakage inspection or rather check ups.
