NEW PROBLEM(S):

[Stewart G Griffin]

2 separate sizes?

[choptop]

I think it depends on truck. 1/2 ton is 5/8 i believe

[HAULIN IT]

Yes, Pugsy is correct, the heater core has Two different size nipples 5/8" & 3/4"  Lorne

[choptop]

You can tell how long its been since I replace heater hoses on my trucks,lol

[Stewart G Griffin]

OK, perhaps i need to back up the train and be more specific:

This is for the test stand and thus i have no heater core.  We can see that there is a water outlet(fig.e) on the intake manifold here:



And on the radiator there is an opening(which i've previously plugged, but could unplug if nessesary) here (fig.f)



What do you suggest i should do?  Since the outlet "e" is already in the block, i would rather just leave it;  Is there a way i could run a short length of hose and plug the hose somehow?

[choptop]

I wont run heater hoses on my test stand. You can just take a short peice of hose, and plug the end with a larger bolt and hose clamp, or get a hose nipple and cap from the local harware store and put it in the end of a short hose and use that as a plug for the one in the intake.

You have another outlet on the water pump.
Just loop a piece of 3/4" hose to the 2 outlets.

[Stewart G Griffin]

That's true.........Duh!

Thanks again.

Why not just plug the manifold too?

[Stewart G Griffin]

Well because i figure it's already in there and not leaking and therefore i don't want to take it out and have to put it back in and possibly it might start to leak.  i'm like that;  i'm the type that likes to pretty much leave things as they are for fear that i might not get it back the way it was even if further adjustment could yield greater benefits.

It's sort of like how alot of people are nervous about taking out distributors.  i have since, out of nessesity, gotten over that task however.

Should you have to remove any pipe thread fittings, this applied to good clean threads is all you need to ensure a good seal.

[Stewart G Griffin]

All hoses done.

If we could revert back to wiring, what about ground?

[choptop]

Bolt your battery negative cable to the block. ANy good clean place should work. I usually bolt it to the back of the head on the starter side

[Stewart G Griffin]

System grounded.

Next question, when we want to fill the bowl of the carb before starting, where should we do this at?  J, K, or some other place?
