M62TU New Water Pump Leaking

[smiked1]

My water pump seized. I immediately shut down, before my belt even broke. The belt smoked a lot, but didn't run long enough to break. Coolant dumped everywhere. It was tough to tell at night where the coolant was coming from. When I took the failed pump out, part of the bearing was actually sticking our the front of the pump. So assumed it was coming right out of the shaft.

I installed a new pump, and proceeded to fill the coolant. When I got to about 2 gallons, it started dripping from the front of the engine. It seemed to be from around the pump. I could even see coolant around the gasket at the top of the pump, and possibly some pooling towards the front of the valley under the intake manifold. Not sure if coolant on top of the engine may have already been there from yanking the upper hose, and dumping some coolant in there.

I assumed I must have torn an o-ring, ripped the gasket, etc. So I bought a new gasket and o-rings, tore the whole thing down again, and meticulously re-assembled everything. The o-rings and gasket I originally installed looked perfect. I started filling the coolant again, and the same thing is happening. I hit two gallons and it pours out the front of the engine. I can't quite tell where it's coming from, but it's not a slow leak.

This has me completely puzzled. If anyone has any useful suggestions, I'd greatly appreciate it.


Thanks.
