Well we haven't yet got the coolant hose going into the intake manifold to seal properly as it keeps coming off and leaking coolant everywhere. My question is what are you guys doing to make the hose stay in the manifold? Here is a picture of the hole in the manifold I am talking about. Tell me what you did and what will work. Would tapping the intake work to hold it so the pressure doesn't push it out again for the 3rd time. It is actually my heater hose. What size tap would work if that is the route I need to go to make sure it is done right and fixed permanetely.

Thanks guys.

Mine is still in process (ok, it's on hold), but I plan on bringing the heater hoses to the back using the stock 4cyl steel heater return hoses. I have mine, and bought a second one for the other hose. I'll route them in the stock location, then run rubber line to the inlet/outlet on the alt bracket.

I've looked at your post several more times because I don't think I answered your question. Are you trying to connect to the hole under the snout of the supercharger? If so, you'll need to attach some kind of nipple for the hose. I think the hole is too large to tap for a 3/4" pipe thread, so I'm not sure what you'd use.

I was thinking maybe a freeze plug. That should work? Anyone else using one for that in the manifold?

Why not just use the stock 3800 setup and take the heater output from the outlets on the water pump?

Too much custom stuff going on in my engine bay So a freeze plug would work wouldn't it? Reliably is what I mean.

I was thinking about using a pipe-thread tap and then screwing a pipe fitting into the intake with a hose nipple on it. I don't know what size it has to be, I have not measured the hole yet but that is always something you could try.

A 3/4 inch NPT pipe tap is perfect for the hole. You need to drill it to mmmmm 59/64 if I remember correctly - whatever the 3/4 inch pipe tap calls for. I tapped mine while I had it apart, but before that, I ran the GTP plastic elbow into the intake, and on the other end of the elbow I forced the heater hose around it and clamped off. I held the elbow in with a small angle iron bracket using one of the intake manifold bolts.

Hope that helps.
