Surge tank cap pressure rating

[beckel]

Just purchased a new surge tank cap from Kascar and the new unit they sent me is rated at 16 lbs. The parts book calls for a 15lb. unit. Do you guys think this is a problem? I dont see 1 lb making a difference but what do you guys think?

The cap you got from kascar was for the radiator it self or the actual surge tank?

The radiator does not have a cap, only the surge tank.

The boiling temp of water increases about 3 degrees for every 1 psi in pressure. The water in your radiator will now boil at 253 instead of 250.
