Lead for, 456 550 575 Coolant Caps, overflow tank

Should you do a search of the archives there are a number of threads about this subject. Many of the experts on here have changed the necks on their coolant tanks to adapt to normal radiator caps. Some for convenience of easy affordable replacement, some to have more flexibility as to cap pressures. Common knowledge is that the OE piece, a 1 bar unit, is marginal at best. And the recommendation is to have it checked and or replaced more often than you would think. Reason being maintaining proper pressure in the system is instrumental in proper cooling.
There is a member in the Fchat parts for sale classifieds selling exact OE new 1.0 bar caps for an affordable price relative to dealer prices. Not affiliated with this member but purchased a couple caps. They are exact and as described. Just a FYI for those that might be interested but do not peruse the classifieds on a regular basis.

John thanks for your comments. And Brian's quoted comments are exactly what I remembered and the reason I replaced my cap about a year ago.
Like Taz I ordered couple spares for some day.
Had the ocassion this past weekend to use one of my spares and it felt good. A like new flexible brake line on my hardly driven Olds 442 had collapsed during a fluid flush. New discontinued spare had been saved for years. Just went back in the house, found it, fixed it and moved on. No delay or trip to the parts store needed. A small pleasure for a gearnut.
Unfortunately Ferrari spares are usually too expensive to keep.
