The hose between the water pump and the cylinder head ( a short hose about 3 inches long) is starting to leak. It appears that you need to remove the water pump to replace it.

Are there any tricks to replacing this thing or ??

Thanks
Alan

usually you can remove the tstat housing and that will make it possible.

did you try tightening the clamps? often that will stop the leak.

I would be surprised if this can be done without removind the water pump. The gap between the water pump and the head is quite small.

You cut off the old one so that's not a problem. Your choices when fitting the replacement include:

- set the replacement in boiling water to make it more flexible

- trim just enough of the pipe extending from the head so you can fit the replacement. Look at the position of the clamp around the slimmer section of hose and determine how much you can cut. There's no bead to worry about.

sounds like my experience with the older engines wont apply here, sorry. but you still might be able to tighten the clamps.

I have replaced this pipe without replacing the waterpump. It is a B***H but can be coaxed into place, rest assured. Do not trim the new pipe!

If you are going to cut, it may be better (though not necessarily easier) to cut it from the water pump end, not the head end. The water pump is easier and cheaper to replace than the head.

If I do have to 'remove' the water pump -- it looks like pump is self contained - as if loosening the bolts that secure it to the block would do the trick. Or am I missing something.

The hose isn't leaking right now but it was and there is a small cut on the side of it. So I would rather do it before not after it blows.

Loosening the bolts is much much much much much much much much much much easer said than done

There's an o-ring between the pump housing and the block. If you pull the pump to replace the hose, replace the o-ring. Given the amount of work, consider replacing the pump.

just cut about a 1/4 inch from the cyl head pipe. then the hose
will slide in. i don't cut the pump side due to core issues.
not that hard really. make sure to smooth out the cut edges
so you don't damage the hose. some replacement hoses are thick.
make sure the hose is thin or original.

I agree, I did the same, its not a job to look forward to...........but very pleasing when completed!
