changing water hose on deuce

[rizzo]

My M109A2 is leaking on the two hoses on top of the heads that connect the intake manifold to the top of the head. Anyone ever change these? is there an easy way?

Pull the valve covers off............then unbolt the two water manifolds and try and pull them towards the valve gear as you pivot them up to pull the hoses off

Installation is the reverse.

Watch for broken off bolts when removing the water manifolds, exercise caution.

When finished, look for mud

Yeah, I have changed all those at one time or another. For the hoses, cut to same length as originals and lubricate slightly so that they can slide back and forth as you install them. I cut my own gaskets when needed and use a gasket sealer (T-stat housing).

Bjorn,
So, is it possible to change those hoses without taking that manifold off? I didn't attempt to change mine because I thought you had to pull those to get the hose back on.

There are several previous posts covering this same question. Search for "change hose" or "hose manifold" in the deuce forum.
In your picture above, that(purple circle) is the thermostat. Pretty easy to do, I did mine without removing the valve covers.

did you guys make your own gaskets for the water manifolds?

 

[doghead]

I was able to reuse mine with a light smear of RTV. Some guys have ordered new ones first and others have made their own. Go easy on the bolts in the aluminum manifold.

I had a set becuase I bought a head gasket set for when I had to pull my heads.

They would be a reasonably easy gasket to maket......they look like a smaller version of a small block chevy thermostat housing gasket.

thanks everyone!!

Yes, the key is to be able to slide the hose as needed and nothing has to come off. The originals may have to be cut to be removed, though.

Dont forget the 6 new gaskets you'll need for the water manifolds...

I have a question about the water manifold bolts. I've pulled at a couple of mine, and it didn't feel right, now it's bugging me. (nothing's broken as of yet). I'm wondering if these thread into blind holes, open holes, basically how complex is the drilling and removal process (and what's on the other side of the hole) if I'm stupid and try to remove the manifolds anyway instead doing what I should and doing it the much more practical way?

I would suggest that you use a tap to clean the threads (3/8-16) and the gaskets are easy to cut from gasket material....an exacto knife works great and a punch for the bolt holes.

I was just looking at mine today. Is the hose 1 3/4 inch? Also, is the hose behind the oil filters 2 inch like the upper radiator hose? I am pretty sure they are but I am eyeballing it.

Never mind. I searched old posts. Who has the water manifold/jacket gaskets besides Memphis?

I would guess Boyce Equipment or Antelope Valley Equipment or maybe White Owl.
