Koyo radiator - cap?

[goldtop]

Famous leaky radiator (at 117000 miles, not too bad). Am ordering a Koyo, as it's so well documented here through Kaz' blogs and others' contributions.

Qs: is the cap typically included? A few supplier sites appear to say that it isn't. And is there an NSX-specific pressure spec?

The pressure cap fits onto the expansion bottle in the engine compartment. The radiator has no cap. Don't lose the cap,it's more than £40 from Honda

Thanks. The car is at the storage co, and I had just seen in the Koyo advert text that caps were not included. Seems that's a generic note and not applicable to the NSX.
