96 Taurus Duratec is leaking coolant at the hose connection to the top of the intake manifold area on the driver's side. The other end of this hose connects to the metal pipe from the water pump feed. The hose connection at the water pump pipe is accessible, but the manifold end is buried among a number of obstructions.

I thought of purchasing one of those remote-hose-clamp pliers, the kind with a block that you put over the prongs of the constant-tension clamp, and it has a cable that runs to the pliers part. It doesn't seem, though, there is even enough room in there for that block at the end of the cable.

I took vise grips, clicked them into the clamping position, open the jaws with the knurled knob, placed the jaws of the grips over the clamp prongs and then tightened the knurled knob. It helps to have a headlamp or other directed light to see what is going on. To drive the clamp fully open, I used pliers to turn the knob. Be careful about working in proximity to the battery -- either remove the negative terminal or cover the positive with a thick enough cloth.

The vise grips did the job -- you have to wiggle a bit, and you ,may have to unclamp them and repeat the above procedure as you work the hose clamp up the pipe connection.

Now what? How to I get the hose off at that end? There is no way to get a screwdriver in there to loosen the hose off the pipe -- are you supposed to do a major disassembly of the intake manifold and other parts? It is still not clear how to get access as the hose is shoved over the pipe connection flush with a flat surface. Is there enough room to wiggle in a coolant hose removal tool ("mechanic's pick")? Do you have to cut off the hose, but can you even get a knife blade in there?

Oh, one more thing. I got the hose off at the water-pump feed pipe end, but it appears the factory put the hose on sealant that has left a residue on the pipe connection? Do I have to scrape all that off before putting on the new hose?

Thanks!

I've had to remove that hose on a couple Gen 4 Duratec's so I know the frustration you are experiencing. I can't remember if I removed just the throttle body or the entire upper intake for easier access but either way that only takes a few minutes and could save a lot of headaches. After all the years that hose has been on there you'll probably have to slice it with utility knife to get it off.

You can refer this thread for your issue. Hopefully it can help.

A year later and getting tired of topping off coolant, I had to follow your suggestion and cut the hose at the manifold connection with a utility knife -- the kind with the retractable blade. The suggestion I have seen online is to twist, not pull the hose to break it free, but that only worked on the far end, not the manifold end of the hose.

You have to reach down in there to cut it at the base otherwise the hose won't pull loose, but a sharp blade of that type cut through the rubber coolant hose much easier than I thought it would. I was also able to reach down in there with the knife, even though I was only able to cut the hose on a diagonal. I left the upper intake and the throttle body in place, though, using vise grips to compress the tangs on the hose clamp as I said in my earlier post. I had to use a long, stout screwdriver to help get the clamp in evenly and past the lip in the tube that the hose goes over.

I also disconnected the negative on my battery -- I don't like doing that because the engine forgets its engine tune settings, but better that than touching the battery positive with the negative still connected to the engine compartment ground.
