How do you change the manifold gasket on a 2000 Nissan altima?

Answer 1

The Intake or Exhaust ? The intake manifold is on top and Channels air to the valves. A local library will let you make (for about 15 cents each) copies of the pages you need to do the job correctly.Most important safety. remove the fuel pump relay after you start the car to drain the pressure from the fuel lines. Let the motor run out of fuel and die. If the car can not be ran, disconnect the battery Neg - (ground). let the car set a few days because the fuel injection lines have 50 or more pounds of pressure in them. You have to remove the air inlet ram tunnel, throddle cable, vacuum hoses. (use masking tape and pen to mark 1 goes to 2 , 2 to 3,4 ,5 etc. each time you separate a hose. WEAR SAFETY GLASSES AND RUBBER GLOVES. Drain and save your antifreeze. You need a special tool to separate the fuel line connection. You have push the tool (plastic or metal ring) inside the connection (spray a little oil in area you are going to push the tool in first might help) to move a retaining spring, (try to do it under a rag in case there is pressure) then pull apart the connection. You might need to remove the serpitine belt, Alternator, and Power stering pump or A/C pump. Be very careful moving A/C pumps and hoses it is pressurized to much movement can cause it to leak Freon. Move the plug wires. Loosen the bolts from the middle to the outside in a cross pattern .
