Looking for coolant cap

Yes they work. I have a 79, and it fit perfectly. You can pick one up at Pep Boys, if you have one in your area. If not, they probably have them at Autozone.

As a very-good mechanic has pointed out to me, one must NOT assume that just-because a cap will fit does not mean that it will 'work'. I'd test it before driving off with it - if it doesn't hold the correct pressure, I'd return it for a refund/exchange. I bought a brand-new cap from Rutlands, and within four months it wouldn't hold its correct 0.9 BAR pressure rating.

 

My cap has been on for about three years, and it works great!

 

11230 fits fine here. Seating depth is almost the same, the Fcar cap seat is just a tiny bit deeper by my measurements, I figure at most the Stant cap is down rating about 1-1.5 PSIG due to possible mount seating depth difference.

I did have to work the cap on and off a few times until was real happy about being installed, it went one way, but wouldn't go on 180 degrees rotated at first.

What pressure do you need? I may have an extra Ferrari coolant cap in my little box of extras that you are welcome to. Its for a Mondial 3.2, but I think they are all the same. Just let me know.

 

For some reason the factory caps do not work on my 328! I have two (.9 and 1.1 bar) that always cause the coolant to overflow. I use one from Pep Boys that is problem free.

 

Several years ago, a Ferrari dealer confirmed to me that some of the coolant tanks were made with slightly too-deep necks. I had the "overflow all the time" problem (even after bleeding and with new caps) so I put a fender washer in the neck, which raised the seating surface just enough that the problem went away and has never come back in over five years!

 

You just need to adjust the cap a little to make it fit easier. Take a pair of needle nose plyers and bend each tab on the cap . Do a little at a time and when it fits you'll know. Mine has been on for 5 years and no problems.

 

I'm not a big fan of Stant - have had a few which were supposedly equivalent replacements and they were definitely different in dimension and didn't work very well.

Here's an italian made OEM-type cap that works well on my 308 and mondial - have bought/used a couple of them now. I'd go with the 1.1 bar version (slightly stronger spring) as this seems to prevent weeping.

Stant 1.1 bar..... $10. DONE.
