also anyone have any recommendations for radiator reservoirs? do they help in hot weather? what is the difference in how a catch can and a siphon back are constructed? photos of installed setups? thanks

They should all siphon back to work properly. Basically it's a bottle with a tube that goes to the bottom (coming from the radiator overflow) and a breather hole in the top of the bottle.

Lot of fellers use extra winshield wiper bottles.

To make your rad suck the puked fluid, you just need a later model rad cap. One with 2 rubber seals instead of one.
Mine is run to an extra indshield washer resivour as stated above.
