While attempting to get the top heater hose off the valve, the hose fitting snapped like a twig. So I had to remove the valve and run both heater hoses to the firewall. Will this be a problem? I also plugged the vacuum line going to the valve, is that the proper thing to do?

Pat Blank did pass the time by typing:

Will this be a problem? Nope. Not near as much as having that snap while you were on the road. > I also > plugged the vacuum line going to the valve, is that the proper thing to > do? Yep. Otherwise you will have a vac leak and that can cause all sort of wonky things. > Please forgive me for being a PITA. :/ Ok. :) ...seriously.. It's failure to ask questions that is bad. :) -- DougW |
