Coolant Bypass Replacement

Ok I Finally Got My Replacement Coolant Bypass Hoses & I'm Wondering How Difficult Of A Task Is It And I Was Wondering If Anyone Had A Walk Through On It That Would Really Be Helpful......



Thanks In Advance

If your just doing that, just remove the hard air intake pipes,move the PTU back, drain and remove the radiator and hoses, and the fan. Then remove the upper aluminum water pipe ( 3 or 4 6mm hex heads i think). You will need to reach up in there with needle nose and take the clamps off the old coolant bypass hoses. Pull the pipe out, take the old hoses and clamps off ( a total of four). Tap the new ones on and place the rear clamps on. Go ahead and put the other clamps on all the way towards the back as well. Make a seal on the coolant pipe and push on, making sure both hoses go over the pipe. Screw it down and move the second set of clamps moved to the back towards the front to hold the coolant bypass hoses on the coolant pipe. Reassemble in reverse order.

Here is a link, but not to much help with the bypass hoses, but there are some pictures to look at.

You might be able to do it without removing some of that stuff, but i prefer the space. Also, its a pretty easy job.

Here's an after shot of my delete (VG30DE in a J30t). I left the metal vacuum lines intact.



If yours in an automatic transmission, it's best to not delete connections to and from the length of metal tubing that heats the Air Regulator to pull the engine idle speed down as the engine warms up.

There are so many good things to be done as part of a plenum pull.

After A Full Days Work (10:30 - 5 P.M.) I Finally Got Everything Back In With The Bypass Hoses Replaced With Silicone Hoses, It Was A Real PITA Seeing As How The New Hoses Were Still Tight So The Goose Neck Couldn't Slip Right Back On But It All Worked Out (With The Exception Of A Lost Hex Screw ) But All In All Thanks To @dantesdoom For The Walk Through It Was A BIG Help

Yeah man, i just finished my timing belt job having to do that in the process. Glad i could help (and that you could understand what i meant lol). For future advice, you might want to work the hard pipe onto the silicone hoses a few times before you make the seal and do the final install. It will slip on a whole lot easier. I meant to tell you that before, but it slipped my mind.
