  A:

  Before you make any move of pulling out the intake manifold, get a hold of your stereo's negative terminal then disconnect the battery to get beyond the anti theft system code if there is any. Pump out the coolant into a mixing bucket and then, remove the air cleaner assembly, the throttle body, the fuel injectors and the air intake plenum. It is also important to label all the remaining wires, hoses, and brackets connected to the intake manifold and the coolant outlets with new labels and remove them from the original bundle. Loosen and take off the intake manifold to engine bolts starting from the outside and going to the inside to make sure that the manifold is fully detached from both cylinder heads. Based on the above guidelines, if the manifold is stuck, do not use force and pry between gasket mating surfaces as this will damage them. For installation, scrape off the gasket material and sealant from the manifold and cylinder heads and then wash with lacquer thinner/acetone. New gaskets should be used and the manifold put on the engine; be certain the gaskets stay in position prior to putting the nuts or bolts; starting with the interior bolts and work towards the exterior. Slightly over torque the nuts or bolts in three or four operations, starting with exerting an equal amount of torque from the center in order to avoid distortion. Install the remaining components back in the reverse which it was removed, fill the cooling system and start the engine and check for any fuel or vacuum leakage or any leakage in the coolant.
