Remove heater hose fitting from Alum intake

Does anyone out there have any ideas on removing an original steel heater hose fitting from an Aluminum intake? I have already used a heavy duty air impact to no avail. I'm aftraid I will twist the head off or break the manifold before it lets loose. Any ideas?
Thanks

Put a litlle heat on the fitting ,then shock it with a hammer, spray with a lubricant(wd40) let it soak in good then use a socket with a rachet to work it out slowly, tighten and loosen back and forth a litlle at a time..

Mine is a factory 70 Lt-1 mannifold and I definitely don't want to damage it. I cannot believe the tork I put on it already and the thing doesn't budge.

Re: Remove heater hose fitting from Alum intake

Steel and aluminum always have these corrosion issues, causing thread corrosion to swell. If you can, maybe you can collaspe the fitting by tapping with a chisel on the outside of the body. If you have the solid bushing type, you could try to drill out the inside and try to collaspe the wall also.
Soaking it with PB Blaster or LPS will help also. It also helps to have the manifold off the motor. But do use caution with the manifold.

Re: Remove heater hose fitting from Alum intake

I do have the manifold off the engine right now. It sounds like the best thing to do is to soak it for some time. Since it is located on the right front I may be able to get the whole thing submerged. I'm afraid to use any kind of useful heat around that aluminum.

Re: Remove heater hose fitting from Alum intake

i tried to get one out of a 69 Z intake with no luck .ididn't want to rip the threads out so i took it to a machine shop. i think he drilled it out till it was so thin he peeled it out. saved my threads and me a lot of hassle!

Thats basically what I was talking about, keep drilling center out until the wall is thin enough to basically peel out. Will involve some large bits.

Re: Remove heater hose fitting from Alum intake

I had a plug in a 68 Z/28 intake. same problem-i actually had a breaker bar and cheater bar set up, and still couldn't get it off: took it to a machine shop and they used heat and drill; be careful-you don't want to hurt that manifold. Good Luck

Re: Remove heater hose fitting from Alum intake

Grind down a hacksaw blade and make 3 or 4 cuts on the inside to relieve some pressure. It will make life a little easier. Just don't go past the threads. Soak and heat if needed. Better to lose a fitting than manifold threads. Andy

I agree. The best thing I've found for soaking is PB blaster. I did a longtube header install on a 99 trans am a few weeks ago with 125k miles, and he soaked the bolts every day for a week and I had no problems with any of the bolts. Works like a charm.
