Questions on AC low pressure port and missing cap
I discovered that the cap on the low pressure port of my 2004 T&C van was missing and wonder if this has caused any problems. Is its purpose merely a dust cap (if so would any tight fitting cap suffice) or does it have other purposes? Next problem is where to find a replacement without being raped by the dealer. Anyone know where I might locate one? Frank |

Everytime I have my A/C serviced, I always check for these before leaving the shop. Very few take the time to put them back after the work. KM |

Questions on AC low pressure port and missing cap
Thanks for the response - will try a salvage yard. Still not sure if the cap serves any other purpose than to keep moisture and dirt out of the port.

Questions on AC low pressure port and missing cap
as long as the actual valve is still in the center of the port. that's what
holds everything in . the cap works like a valve stem cap on your tire. keeps dirt out etc. "ECLiPSE 2002" > wrote in message ... > > Thanks for the response - will try a salvage yard.

Usually if there is a leak you'll see oil. If you run by an AC repair shop they may have a cap laying around they would give you. |

Also dirt will get in on the next recharge |
