Leaking coolant from behind the engine

Does the hose go to the nipple to the intake manifold? I have seen a lot of those nipples break off the plastic intake manifold. It looks too small to go to the heater core.

I just looked at the pictures you posted again that is the coolant line that goes to the nipple on the intake manifold. That nipple most likely broke at the intake manifold is that where it is leaking coolant and cracked where the nipple comes off the intake manifold?

I want to help you here but need to know whats broken or leaking? Is the nipple on the intake manifold broken? Or are you just trying to replace the hose? That hose is a return hose from the intake manifold to the coolant bottle. It is not a heater hose. Let me know so I can help you out.

That is a hose clamp holding that hose onto the nipple on the intake manifold. So are you looking to just replace that hose? If so it runs from that intake manifold nipple to the small nipple on the coolant bottle. We just used bulk hose when we replaced that hose on all the different S model Saturn's at the Saturn dealers I worked at. We just asked for roll of hose and told them how much we used.

If the nipple is the part you have to replace that you will have to replace the intake manifold. It is in a plastic orifice if it is leaking that means the plastic manifold is broken or cracked. I will get you advice on that in a little while. I am at dinner with my family right now.

To remove the manifold you have to take the negative battery cable off drain the coolant remove all the injector connectors fuel line injector rail map connector throttle cable throttle body etc. The more you take off the manifold the easier it will be to take out. Remove the upper mount by the valve cover the upper dog bone transmission mount under the air box that way you can rock the engine forward to remove the manifold. You will have to remove all the hoses, also all the nuts and bolts holding it on. As far as the fix in the video you posted it looks interesting could possibly work but have never tried so I could not say or recommend for you to buy it and repair it that way. If you want to give it a shot that would be up to you to take that risk.

Here is the link to a brand new factory manifold from
parts.com for $238.00 plus shipping i have bought some factory Saturn parts from them recently there reasonable prices and ship pretty quick.

Also, i found a new factory manifold on eBay with no warranty for $234.00 with shipping. If your interested in that let me know but i would get the one from parts.com for a few dollars more. I saw the repair kit on eBay for $75.00 with a DVD instruction video. I just do not know enough about that repair to recommend it or say its a piece of junk. I will let you make that decision either way you have to remove the manifold to repair it so keep that in mind if the repair did not work correctly. Here is some advice i will give though if it were my car i would get a new manifold and replace it because with my luck the repair would not work and i would probably have to take it all apart again and end up replacing the manifold anyways.
