heater hose outlet pipe question
 

Hi Guys...question on a 3.0L v-6. I've got a Generac 30kw standby generator... it has a ford v-6 3.0 engine. The water pump has a heater hose outlet pipe... typical metal pipe with a bubble flare at the hose end where you clamp on the heater hose.. since the generator has no heater this fitting has a rubber cap held on by a screw clamp... every couple of years this cap deteriorates and either sprays antifreeze every dang where or just seeps till the coolant level is below the sensor and the generator will not run (no/low coolant fault).. the metal fitting seems to be press fit into the water pump (no obvious threads or hex fitting to screw it out. I don’t want to screw it up and it cost me a new water pump... and I don't want to remove half the front of the engine to get the water pump off..

the question... is there another way to seal this metal fitting permanently instead of the cap that deteriorates ?? something plastic or metal that can stand the heat and vibration and not leak...maybe epoxy'd in place ??? I’m about ready to drive a wooden plug in it !!! somebody has got to make something that will work...

I'm recovering from hip replacement surgery so I want something relatively easy and cheap... suggestions ???

thanks
John
