Back from the sea and wanting to finish what i started.

2 yrs ago I took the 350 out of my 94 fullsize and had it overhauled. since then I've been deployed, Just got back and wanting to finish it.

The only problem is the small hose from the top of the water pump. Where does it go? I took photos of everything before I left, but not this area. Anyone know?

water pump

In combination with the other hose connection on the intake manifold, these should go to your heater core.

Thats what i thought, but the heater hose goes to the rear of the manifold and there is no open port or a tee elsewhere towards front of manifold

You should have more than one heater core hose... One should be supplied with pressurized water/coolant from the pump while the other flows back into the intake manifold.

yep. the other hose goes to the radiator from the core.

The rear hose is the pipe/hose into the quick fitting at the back of manifold.

So both heater hoses are accounted for. Just this little hose is being the rebel.

You know, the sub is easier to work on then this.

That's different.. But if that is the case, then you can plug that hole.

Ok, well this is turning out to be an easy fix. This hose never went to the blazer. This is off my daughters jeep. Your're right the lack of pressure from the pump threw me off, but the pressure is from the manifold. Reason for the high pressure hose and pipe fitting. So I just need to put the plug back in.

Thanks I guess thats why nothing showed up in the photos.... Nothing there.
