I have a leaking valve on my passenger side tag. I have gotten a new valve from FOT. The block is almost out of reach and, of course the one that needs to be replaced is on the very top. Should I just unfasten the block and lower it as low as I can with wires and hoses still attached to get the valve off and replaced? Where the valve is looks tight and I do not see any way to remove it. What are my options?
If it was made where a large socket would fit around it like an O2 sensor socket, removal would be easy. I wonder how much trouble getting a socket made.
I did exactly this on my 01. The limiting factor for me was the amount of airline I had to to work with. I have rebuilt a six pack in place as well as on a work bench now and I'd much prefer the latter simply because it's such a PITA to do again if you don't seat an o-ring properly. Both ways worked for me however.
If you are talking about a round HWH solenoid valve like the ones on the 6-pack manifolds, then there is only two ways to remove them from the manifold - the gentle way and the rough way. Gentle is using a rubber strap wrench. Rough is using a pipe wrench. I was able to successfully use a strap wrench to remove all the valves when I rebuilt my 6-packs,
but I took the manifolds off the coach and brought them inside to my work bench. A pipe wrench will work
IF you have enough room to get a grip on the valve body with the jaws, and enough space to swing the wrench. The pipe wrench will chew up the brass valve body but doing so won't compromise the function of the valve.
