Why is there no seal on the cap, only the adapter bottom. Won't the overflow leak from the cap (since its above the seal)?

The seal is on the neck of the adapter and not the cap. When you tighten the cap, the adaptor seal is pressed into the neck of the the radiator. This seals the funnel to the radiator. Because the seal is in in the neck of the radiator, the overflow hole is beyond (after) the adaptor seal. So, the overflow does not leak.

will this work with a jeep patriot?

It has multiple connections and I believe it will work I love it. Don't forget to run your car and turn on the air conditioning When cleaning out the radiator.

Does it fit a 2006 Nissan pathfinder?

By looking at pics of engine bay, the blue or green should fit it. I Say should only because the blue is the correct size for my 2007 Hyundai Tiburon, however the locking mechanism was incompatible. No the less I was able to completely replace all the antifreeze in car with this kit. Worst case, you may spill a little on the ground
