Water flow in heater?

Hi all,


I want to disconnect the water lines for the heater coming from the engine so I can put new grommets on them. If I disconnect the one going from the engine to the heater (where that "spigot" is) and the other where it joins the copper pipe how much water should I expect to flow out?

Thanks!
Chet
 
Grommets could be replaced without removing the heater hoses.

I bought a "generic" grommet packet at home depot that contained two grommets that fit nicely into the firewall for the heater hose inlet and outlet. They're inexpensive and if I were to do it again I would use a razor blade to place one cleanly sliced cut into a section of the grommet - now the grommet could be slipped over the heater hose and walked into the hole in the firewall. A little silicone grease helps to ease things into place. Remember to put the cut section on the bottom where it'll go unnoticed.

I've done that a few times with almost no water coming out.
 
I recommend cutting the grommet diagonal to the radius so the ends are tapered. By doing that you can more easily start the grommet by slipping the tapered end into the gap between the pipe and the sheet metal. If you are lucky you may be able to slide the whole grommet in a circular motion until it is all installed. I'm sure even high end shops do this to save large amounts of time and customers money. You can even get some black silicone and put a dab on the cut ends after it is installed. Alcohol ( isopropyl, the rubbing type, although good whisky may also work) will also be a good lubricant and evaporates to leave no trace.

No, if using whisky, drink the good whiskey after you're done, use a cleaner, like 409, that evaporates.
