The heat has been off all summer, but it was a bit nippy this morning. I reached down to turn the heater valve on and got wet. Silly little valve peed on my hand!

So, it is time to get NAPA 660-1000 and replace the rubber. Should I also get new pieces of heater hose? What size? Should I drain a couple of quarts of coolant from the engine to get the coolant below the HCV, or, just unhook the coolant hose at the bottom of the HCV and let it drain into a bucket?

What scares me is the copper thermostat tubing will probably not come out of the heater box. Can I just replace the NAPA 660-1000 while it is in the car and I am upside down? Or will I be in need of a proper workbench?

Thanks,

Klaus

EDIT: How in the heck am I supposed to get the heater box apart!? The screws come in from the firewall side, I think they are phillips. I have nothing short enough to turn the screws???

After looking at the engine bay, there is nothing to drain except for a few drops. Easy on the engine side, just need to measure the hose. The bottom coupling is showing signs of a leak.
