My SPF has a CST brand radiator cap, and it says its a 7 lbs version (Marked "T-7 7 pounds).
Its getting rusty and has leaked a couple of times (just a small leak), so its time to change it out for a new one.
Two questions:
1) Is the 7 pound cap correct? The car has never overheated in the 8 K miles I have put on it.
2) Your recommendation for a "good looking" cap. Most radiator caps are
PUG UGLY.
