I need to replace the collant pipe that runs underneath the intake manifold, from the thermostat housing to the throttle body. How big a deal is removing (and replacing) the intake? Is there a good procedure written up anywhere? The Nisssan manual itself covers this only as part of removing the heads. Any estimate of time? Anyone have any experience replacing this pipe? Dealer wants about $500 + parts for this.

Thanks in advance for replies.

 

A question like this is hard to us to answer because we don't know your mechanical abilities. For a avg DIY's I dont thing it should be hard, it's just a simple remove/replace of parts.

good point. not a pro but pretty darn solid. so long as it doesnt require putting a car on a lift very things i cant manage. just a time vs dollars issue for me so wanting some been-there-done-that experience before i start or pay.

 

i have an extra water pipe for a ve if you want to shoot me an offer its in good shape ill take a good look at it today and make sure.....
i just went out side and checked it out its in damn good shape the only dirt on the thing is on the outside the inside as far up in it as you can see is smooth as a babys butt .

this is craig b's site. first few steps show how to take off the intake manifold. the pipes are held together by a few belts that just need to be unscrewed. and wen you say thermostat housing do you mean the sensor? took me about 1/2 hour to take out the whole stock air intake including air box, pipes etc. hope this helps answer your question.
