2003 Nissan Xterra 4-cyl. U-shaped hose under intake manifold split, leaked out antifreeze. Have one side off but the other side is hidden and cannot see how to get to it. What to remove to get to it?

SOURCE: intake manifold cover

remove oil cap steam an it should just lift off

mine is doing the same, it's your pcv receptor on the manifold. that hard plastic cover is actually part of the intake itself, if it "came off" it would cut your intake in half. that seem seals the two halfs together. you gotta pull the whole intake off and replace it... or jimmy rig it.

it could but- check passenger side front where heater core line go into manifold right behind alternator the hose line is connected by a press clip into an alloy fitting this fitting gets eaten away by anti freeze and hose angle pulls back on fitting the part is $18 at dealer and is screwed into manifold use caution if ur r going to replace at very edge of aluminum manifold---and check ur water pump bolts the 2 longer ones should have a lock sealant on them they bolt in thru a water jacket

There is a heater core bypass pipe that runs from the block (under the manifold) to the bacl of theengine where you will see a flat rectangular "sheet metal" thing with a pipe coming out of it. The a rubber hose connects. You need to pull the top air plenums and intake to get to it. The p[ipe flange bolts to the block with silicone rtv as a sealant.

You have to remove the upper intake manifold. You'll need to unbolt it and disconnect the hoses and connectors and move it enough out of your way. It would also be suggestable to get a new gasket for the upper intake manifold, increase the old on breaks or comes a part, during removal.
