Changing heater hoses
Ok, I know that someone has changed the heater hose on the intake at the very rear of the engine without pulling the intake. Yes, I know that ideally I should pull the intake and replace the crossover pipe while there, but I do not have the ability to do it in a timely manner myself (due to health issues), and the local shops want $1,000+ to do it....which is also out of the question right now due to my health issues. I've heard of people doing it, but damned if I know how. I cannot even get my hand back there to reach the clamp. Right now, I just need to get the hose replaced to stop the leak, and I plan to do a proper repair (pulled intake, new crossover tube, etc) come spring or early summer. So, can someone help me out ?

Where's it actually leaking ? Is it in a spot where you can cut the heater hose at the leak and put a brass 5/8" splice in the hose with a couple of hose clamps? That'll get you by till you can do a full repair job.

Been there
On another board, a guy said he was able to replace his by pulling the throttle body off and reaching back there. He said it was still very tight, but he was at least able to get it done. I might try this as soon as I can. I just can't remember whether that's the intake or outlet hose that's hooked to the intake, and I'm not looking forward to screwing with that damn "quick connect" on the hose at the firewall either. I'll have to you tube how to get that off because I can't remember. I just remember it was pain in the ***.

Yeah they make a tool for removing those heater hoses. It's a 5/8" fork you slide over those white plastic clips, push the hose toward the firewall to get the clip to release, then pull the hose away from the firewall and heater core. With them out of the way you have a little working room back there. You can probably get some needle nose ViseGrips on that hose clamp.

I need to flush my heater core and I've lost my tool I bought... I had to take off my upper intake and replaced all my heater hoses at that time. I also had to replace the metal pipe on the intake.

That's what I'm trying to avoid. How much did you have to break down the intake to get off ? Could you just pull the plugs, and take off the throttle body, or did you have to pull the fuel rails, EGR, and almost every other part on the intake to get it off ?

If I remember correctly I pulled the CoP's and I think the fuel rails. I had a leak at the rear too and I think I had discovered once I got it apart to be the metal pipe coming out of the intake at the rear. That was fun to get out and replace. I replaced all I could while it was off including the knock sensor because I didn't want to do it again. Replaced the metal pipe from the water pump nipple to the rear of the intake. Also did the heater hoses that split for the rear heat. It's been a couple of years now since I've done this so I'm not exactly sure why the CoP had to come off but I think it had to do with the fuel rails and injectors Wasn't a critical vehicle for me so I took about a week or two. Was hell leaning in there to do this over a bit of time. I couldn't work on it long before my back and stomach were killing me. I think taking out the fan shroud would let you sit on the radiator support and make less body fatigue.

The back and stomach fatigue will be what kills me....along with a bad shoulder. I appreciate the info, it's pretty much what I expected..and was afraid of.

In some cases you really are just better off taking it to a shop and paying the piper ....
