It's tight but I had just enough movement to get the job done. I had a slow trickle after replacing one of mine. I have a 2010 2.5 Outback with a leaky coolant crossover pipe..I have searched over this forum, but I cant find removal and installation instructions on the job.. if it is the top one it is intake comes off and that pipe is EGR. The metal grommets on the three gaskets are there to make sure you don't over-tighten the seal. I didn't unplug the wires to Throttle body because some cars require a relearn if disconnected.

Took several attempts and lots of patience. Also if they are in there might be worth replacing most of the seals that are not so easy access.
I was afraid this would be the answer.
off; pretty easy job. I still have a soft spot in my heart for the Intrigue! Sorry , didn't mean to " step on your toes " !
6 hrs of labor to remove right exhaust manifold, egr valve, throttle valve. Both Intrigues have been sold over a year ago, but this thread in my inbox made me post. Took it back off and could clearly see that the o-ring had already started to degrade and harden in less than a week. 
Nevermind i found out thanks for the tips on how to replace and merry Christmas!!! There very well may have been problems with the gasket supplier, but with this problem being so pervasive to Intrigues, it does not seem that there was an isolated vintage or batch of inferior gaskets. 
when you pulled the old coolant pipe, did all of it come out? This of course doesn't make using the crow bar trick any easier with this stuff attached. Another pair of helping hands while prying is recommended. Got a 2013 XFR with 34k miles on her. i can post pics and guide you if you have 2.5 assuming not too different from 2010.

Only my shop is not as spotless as theirs was.
It also appears to mention that they went after the rear exhaust manifold with a series of extensions, Maybe from the top? crossover The car is still nice, but $leak, $wheel bearing, $AC leak - I think it's almost totalled, unless I use sweat equity, but I think I'm going to have to ask for help on this one.
and only the OEM pipe is worth a damn. The pry bar shortcut worked well after removing throttle body and adapter and left manifold, I removed radiator fans to make that a bit easier, but could probably have done it without that. I did take the intake manifold off. The main crossover coolant pipe is plastic, gets fragile and just leaks. Could these be backed out and cut off, and the replacements be cut down 1/8" to 1/4" yet still have enough engagement to make a good seal, or is this just making it harder? water pump pipe windstar ford tube crossover outlet 1999 It is hard to tell from your close up pics, but egr pipe looks different than mine.

thanks stan for starting this post and for the pointers on the telephone a few days ago! The Crossover manifold uses 3 identical gaskets with metal grommets or spacers and it seems to me that the metal spacers prevent the gaskets from sealing completely and a blown seal is inevitable. Can you find out the part number? 
I dont have a good pic of egr pipe, but it is stainless steel, runs almost vertical, and top port to intake is just under TB.

I have found that it is not so much the aftermarket pipe but the aftermarket o-ring that comes on them.
It did end up being the coolant crossover pipe. $650 isn't terrible if you can afford it. Check the parting seam on the pipe too when you take the o-ring off. The engine starts easier, runs super smooth, throttle tip in transition is awesome, no flat spots in rev range, runs better than new at 108k miles. 
Also, the oil cooler hose does leak. Was much easier than removing right exhaust manifold.
Clean gunk off intake valves and replace all of the rest of the plastic pipes in the cooling system (there are many). Advertising -
When the is in service position, its easy to do the JOB CORRECTLY and see what else is wrong. I'm also willing to bet that the gasket today is the same as it was 10 years ago and will leak again - I'll let you know in another 10yrs :).

for July's Outback of the Month Challenge! Removal of front of car does seem excessive. I did'nt need to do any denting of the exhaust pipe. It's nice to see why I couldn't find a flange on that side of the engine. If you have had to add coolant a few times because of it being out or extremely low then I think that is you problem.

My question is: Is this the solution to the persistent problem of flow, no internal heat at idle,overheating at idle, highway speed (55/60mph) it the engine cools and internal heat is great, then at highway speed gets hot again after awhile, and will cool to normal once revved over 2000rpm.

I'm guessing due to release of pressure/water from these gaskets and the seemingly unique and delicate cooling systems of the 3.5 Intrigue?

GM certainly could have done a better job on designing this one. I have determined that it is the o rings on the cross over pipe.. i just had my 2014 2.5 throttle body and intake man.
