1995 Mercury Grand Marquis radiator

Any chance switch up gaskets and blocked off water port to head?

Intake manifold came completely assembled. All we had to do was slip it into place, put hoses back on, and bolt it down. Where would I look for the block?

So installed no gaskets? could you explain radiator won't take coolant? engine running and adding coolant right?

Gaskets were already installed on manifold when bought it. Filled plastic coolant tank, ran engine, coolant never left plastic tank. We know that the coolant had drained out when replacing manifold. That's why we're trying to refill radiator.

Remove top hose fill up then attach start should take from tank then
