Pressure of radiator cap?

[cb500t]

Need to replace mine on the 2.9 but the cap fitted has no poundage marked on it, can some kind soul enlighten me as to it's required value ? T.I.A

14-16 PSI would be fine.

If you're putting a pressure cap on the swirl tank, make sure it is long enough to seal against the sealing ring and that it has a return valve in it. If you put the pressure cap on the expansion tank, it doesn't need the return valve and can be a standard reach.

Parts list says UnipaRT grc 1110 Quinton Hazell FC53 15IBS but I don't know which type that is.

See below for height of the Hazel one if it’s any help.
