Yes, they are "suppose" to fail in the open position (but don't always do that).

I always put mine in a pot of water on the stove and boil it until it opens. That way I'm sure it will work well when installed.

Once it gets hot and the water starts moving, it should send all the air to the radiator. Check to make sure the level stays up.

Unhappy new 66' econoline owner

Hi, I have a cabover. It's my first classic and I plan to learn mechanic with my truck. What do you mean when you explained about making sure the level stays up?
I have a high temperature problem. Though it stays a little over the middle of my temperature gauge if I stay cruising on the highway at 40mph and up. I don't want to burn my engine so soon, but I don't know where to start looking? I appreciate any input.

By "level stays up" I meant to keep the radiator full of coolant. The air in the system should travel to the radiator to get out.

About the radiator. were you able to get a radiator for the actual truck or is it one that happens to fit? also was it a 2 tube or 3 tube (the number cooling tubes when looking from the front to the rear along the inside edge of the top and bottom tank) the one that was in mine when i got the van is close though i had trouble finding a lower hose. wound up cutting down a hose from another application. mine is not leaking but it's real old and want to be ahead of it before it fails. thanks in advance for any feed back you can share

EB to this point it's also a good idea to put a meat thermometer in the water to track when it opens. Works on the lower temp 'stats. Most scales end at 190 but you can get a feel for the other when the water hits a boil at 212 (depending on your altitude. i think lower at higher elevations?)
