Reply to "Erica needs to get hosed....."

OK, a good day in the garage!

Spent mostly upside down under the dash getting the heater core switch out!!! I can't believe they really need a 23mm nut on that flare fitting......

My valve was locked up solid. In removing hoses I got some amount of water out...disconnected the hoses at the engine and water pump.

Discovered that the fitting into the block is pretty ugly. Gonna see if I can get a new one and somehow get it into the block....providing I can get the old one out! There is nothing but rust holding a new hose onto the hose bib!

Used paper towels to sop up fluids...tried shop vac on the heater hoses.....not sure if it worked properly....acting like hoses are plugged!.....need to search for shut off valves!!!!

Left hose connection under dash looks reasonable. Right connection that goes up to heater valve looks ugly..... about 50% eaten away. Could benefit from new end.....probably need to trim off some of the scarfy section and double hose clamp it!

Heater valve was locked up. Was able to get it apart using article on Pantera Place. Messed up and didn't mark the parts as specified....but this thing either goes together with the passage 180 degrees out.....or partially open at full open or partially closed at closed.

I'm voting for partially open at full open....the copper hose into the heater core isn't all that large.......and I know that we want the valve to shut off the water since it shares the same spot as the evaporator for the AC....so if the valve was open, it would be working against the AC!!


Here is a question for the experts! When the heater hoses are shut off with valves, the Clevelands and Windsors tend to capture water in the water pump and start to cavitate! ...leading to overheating!

How does this setup in the Pantera allow for "some" water flow thru the system to remove the air bubbles!????

In Ford cars, there is an "H" in the hoses just prior to the shut off valve in front of the heater core. Sometimes there is an 1/8" hole in the valve to allow some water to circulate.

This valve does have a tiny slot in it....but when fully closed, this slot looks to be covered....but I did not reconnect to the cable yet to see just how much "on" or "off" I get.


Any ideas????
