crappy plastic heater tubes

[Brad Clayton]

Well it finally happened, I broke my first heater supply tube. used the search engine and found Greg's input on replacing the offending piece.

Quote:

Just in case anyone breaks that heater pipe, here's the replacement procedure:

 

Remove the upper fan shroud

Remove the fan

Remove the 13mm nut holding the P/S pressure and return hoses

Remove the 3 10mm bolts holding the P/S pump and set it aside

Remove 2 8mm bolts holding two coolant hoses at the top left front of engine

Position the lower coolant hose aside - twist it up into the fan shorud

Disconnect the right side injector harness

Disengage the crank sensor harness from the heater pipe

Break the old heater pipe near crank sensor harness

Remove 10mm nut holding pipe to the intake

Fish the two pieces out

 

Install:

Insert the pipe, o-ring end first, between crank sensor harness and upper alternator bracket.

Turn back and forth, Rubik's Cube fashion, to thread pipe into position

Reasemble in reverse order.

 

This assumes that the normal 07T07 recall is in progress, and the air intake, GPCM bracket, etc. are out of the way.

 

If anyone has improvements on this method, please let me know...

 

Be careful! This pipe is stupid fragile...

It went rather smoothly, but still more work than I was doing to begin with. This was from over at the injector recall post from way back.

I remember the first time getting my hands dirty on a 6.4L, THAT was exactly what one of my ex-coworkers forewarned me heavily about. Ever since then, I always pay particular attention to those plastic heater tubes any time I'm under the hood of one of these pieces of shit on wheels.

Pretend that they are very expensive glass. They demand respect.

[Alex Bruene]

They make a sound like breaking bones. Gross.

[Keith Browning]

Yeah but have you ever dropped one on a concrete floor? They make a weird sound almost like a xylophone.
