Not exactly sure where this goes...Heater Core Hose/Pipe

[ehjorten]

Okay...so on my '91 Crew the header core started leaking!  No drips, but you can turn on the defrost and open the heat and you can smell a sweet smell.  It also has started to fog the windshield in the morning!!

So...I got a new heater core yesterday and generally when I do this I get new hoses too.  So...I was looking for a place that sells Gates Green Stripe heater hose.  I found a place and last night I go to measure my 3/4" and 5/8" line lengths on the truck.  I never realized that the 3/4" hose is actually about a 2' length of hose that is crimped onto a bend length of pipe that has a nut on the end, and it bolts into the back of the intake manifold!  This is a 454 truck.  Crap!!!

I go looking on RockAuto.com and do some google searches to see if I can find that Pipe/Hose assembly.  I'm not coming up with anything!

I am going to call the local Chevrolet dealer when they open this morning, but I thought I would put it out there to the community...Does anyone have experience with this and know where I can get a new hose?  I could probably reuse this one if necessary, but it is a 22 year old hose.  The 5/8" hose is just a straight section of hose with clamps, so no problem there!

How about changing the fitting on the manifold so you can use a clamp there?  In that vein, does something like this help?

Called my local Chevrolet Parts Department this morning and the part is discontinued, but apparently still available at a discontinued parts warehouse.  I'm going to stop by the dealer at lunch and take a look at the picture before I buy it.

I'm going to try and do a full write-up on this one with pictures of how to remove, recondition and re-install the heater box.  Not sure how long it will take as everything is taking a back seat to me building my shop.  I think about working on the brakes on the Chevelle and replacing the heater core in the crew, but then I think about the time I wouldn't be pounding nails on the shop!

you can use that nipple posted or one like it then to get the bend you want. also be careful that stock quick connects are notorious for breaking off in the manifold
