Coolant air bleed valve question

Coolant air bleed valve question
There is a coolant air bleed valve on the neck of the radiator hose inlet on the intake and another in what appears to be a 5/8 inch heater hose. Is this second one absolutely necessary or can you successfully bleed the system using only the one on the large radiator hose inlet? I ask because I am having to replace the 5/8 inch hose.

So you're saying you just don't want to hassle with it by fitting the section with the bleed screw back on? My opinion would be to go ahead and keep it, wouldn't take much more time fitting then what it would be to take it off...

No, that is not what I am saying! The hose in question has a leak right at the junction of the rubber hose and the metal fitting containing the bleed valve. I have already checked on getting a new replacement and the local GM dealer said that this hose is showing as being discontinued but that he could possiblity get it for around $200.00. Now as far as dealing with the "hassle", I can replace a section of the hose and fab up a bleed valve--my question was simply will the one bleed valve in the thermostat housing be sufficient or is this second one absolutely necessary. Any time I have bled the coolant system, I have always gotten a lot more air out of the thermostat housing bleed valve than the other one.

$200 would be for the complete heater hose assy, that is both hoses and metal pipe from w/p to heater core.

In reference to post #6, here is how you can replace individual hoses.

bigblackbeasst -- where did you get that bleed valve? That is always my least favorite part of the coolant process; messing up the newly cleaned engine. Much better than a rag which becomes one with the power steering pump pulley...not that that has happened to me twice.

Brass are not very popular, so I only order the nickel plated brass version now. Not accepting Paypals any more this year, as Obama is dipping his hand in that pocket as well. Money orders work.
