Chris the T-stat is really in the engine, not the hose.

Bottom hoses used to have a spring in them for support so they don't collapse under suction. You don't see springs in replacement hoses anymore and I forgot why.

the molded hoses don't have the springs in them, but the flex-hoses all have the springs in them still i think

Thanks, that's what I meant. The molded hoses used to have a separate spring slipped inside them.

Yep, in the old days the molded hoses had a spring inside to prevent collapse under suction. I don't know why they don't put them in anymore. I have seen hoses collapse. I suppose the new engines could have better water pump and cooling system designs but we have OLD style (good) engines...
