Coolant on engine 5.4
I lost some coolant onto the garage floor and it appears to be coming from behind the water pump. The engine block is wet with coolant in the area directly
below the intake manifold. I am wondering if this is a water pump problem or something else? Anyone have this problem?

If it's wet above the pump then I too would suspect the heater hose as the source of the leak. If however it's wet only below the pump then I'd suspect the leak is with the pump. In the second case you would need a new pump.

No but you do have to take your time and not rush it. Take some pictures for reference in case you wonder what goes where after. Tag where vacuum lines go, and get a set of new spark plugs. The plugs are very easy to change with the intake off and you'll thank yourself later for doing them now.

Wow. Great thought about the plugs. Maybe I'll remove the intake manifold next time I have to replace my plugs. It might save me some time. Lol

I have 104000 miles. Just changed the plugs. I have the Ford dvd, an expired one, from a dealership guy that I know. I have to roll the date back on the laptop to use it, but I was able to print out the steps required for the intake manifold removal and installation. It was very helpful. Today I got as far as one step away from pulling the manifold. Tomorrow I will find out whether or not the pipe or the o-ring at the end is the source of the leak. I doubt it's the water pump because of how the water got all in the valley, unless it got blown back there.

I don't think that's what happened. The coolant wound up on the garage floor below the rear of the engine. No coolant spray around the water pump and coolant was evident in the engine valley only. My guess is the tube that goes thru the valley. I will continue disassembly and post the results.

So did you replace the intake? or fix the connection in some manner. Did you get a new pipe?
I have a 2003 with 230k miles and I think this is next
Would you recommend the Dorman intake???
