OK - as Rob says, I'm mechanically challenged. I'm trying to understand the hot water bypass. Keep in mind I have a Royale with gas water heater.

There is a bypass gate valve which is inline under the hood. I thought that just kept hot water from circulating through the auto heater core during the summer.

I think you are talking about a valve that cuts the water heater out of the loop when it comes to radiator circulation. I guess my question is, Why? Wouldn't that circulating water have ethylene glycol from the automotive radiator?

Maybe I'm thinking about this all wrong and instead of hot water from the engine circulating around the tank, cold water from the water heater circulates through the engine.

Gotta be one of the two.

Help.
