part # or description for blow off/return radiator cap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

headed to the parts store for a radiator cap that will let me draw back in from the overflow - last trip, I got the deer in the headlights look. They pulled a 16lb cap off the shelf but it looks just like the one I have (ground puker type). Can anyone described what it would look like - I envision two "seals" - upper and lower so it can blow out and then pull back in on cool down. I'm searching right now but have to leave pretty soon. Thanks all!

Thanks B&B - I don't have a nearby napa though..... I wonder if they can cross ref from one of the big box places.... Do you remember the/a specific application?

79 Chevrolet Impala, any of the stores should be able to cross the #.
