hi i bought a new one with heater out lets $120 not cheep. i then took to my engine man and he welded up the holes and then i put the cups on them that way no chance it would leek. but you could cut down the tube bits and get welded up might be a way of doing it

There is this type but Im pretty sure they only fit the early 149 heads.

There are rubber blanking caps available from autobarn, repco etc.i have used these on my LS in the L J.
Or you can insert an appropriate sized standard bolt or hex drive bolt (neater looking) into the outlet with some sealant. This was how it was done on an engine I bought. It never leaked.
Either method should cost you well less than $10.

I'm sure the early red 149/179 housing will bolt up to the later red heads. Just have to plug two unused holes in the end of the head.

Duggan, early 149 red heads used these housings.

Correct, Dave. Gotta plug 2 holes to use them on later heads.

A pic for those wondering.

hi again dont think you can weld the old ones they are cast the new ones are alloy and can be welded. i welded mine to make sure that the rubber things did not come of just to make sure 

[wot179]

You can weld them up with cast iron rods using a stick welder

Just be sure that the surface is prepped well.

Hi Duncan,

 

Take a look at this thread and look at the third image down that was posted on the 18th of March. 

http://www.gmh-toran...1-heater-hoses/

 

If this is the look you are after then try this

Buy:

1 7/16 UNC tap

1 9.4 mm drill

2 1 inch 7/16 bolts

1 10ml bottle of Loctite 263

2 5/8 rubber blanking plugs

2 Hose Clamps to suit - if you want you can use the blanking plugs and clamps from Rare's

 

Drill tap and loctite the 2 bolts in - fit blanking plugs - will never leak and looks pretty good, (its what I did for my LC)

 

Cheers Brian

As already mentioned,drill,tap,grub screws,thin smear of sealant on threads (cheap arse 5 min araldite),cap if you want.

Alternatively you can bronze up the holes with an oxy.

Alternatively you can chip all the flux off of the cast arc rod and then use it with a Tig.

The 2-bolt lower housing was fitted to ALL 149 & 179 engines, not just early ones. The 2 hoses weren't required because the inlet manifold was not water heated, it was heated by the exhaust.

 

As you can see in the pics, the housing is held by only 2 bolts. The lower right threaded hole is present in the 149/179 heads, but not used.

 

The water hole that you can see on the lower left is not present on 149/179 heads. If you fit one of these old heads to 161/186 & later motors, it needs to be drilled.

 

If you want to use the 2-bolt housing on a later head, just tap out the water hole & fit a hex grub screw (with sealant) & that's it, no welding required.

Chris,

 

AFAIK, the original thread size in the thermostat housing should be 1/2" BSP.

You should be in need of a 1/2" BSPT hex head brass plug which you will find at any Plumbing Supplies or dare I say it, Bunnings, in their plumbing section.

[grumpy xu1]

You'd call it a grub screw in automotive terms & if you have done the 1 on the drivers side, tap the housing & fit 2 on the passenger side rather than worrying about the rubber plugs failing & they definitely do ! Gary.

[madtoranajzedded]

Am i right to say if you use an U piece of hose not
restricting flow for the manifold outlet inlet on
thermostat housing helps in the event of the thermostat
failure... the water can still circulate..

[I'm a Red Motor fiend]

Maz, both are below the thermostat so no.
