Guys, This is all just theory from what I have read, but......
this is how I believe it works.
You, put a blanking cap on the radiator and then, you need a cap that its suitable for your overflow tank.
I bet I got that wrong!

| Post subject: | Radiator Cap |
OK the search function returned nothing. I'm putting a plastic recovery system on the Mini. The guy at Supercheap said my existing radiator cap will be fine. I know that is crap. So I went to REPCO and they gave me RC64-13 replaces CPC 508-13. When I googled the CPC 508-13 it says it has the short 22mm cap. I thought I would need a 27mm cap? Ideas please, once and for all. |

I just put on a new long cap CPC 517-13 by memory, they however are not a proper recovery cap. Just looked in our tridon book, the recovery cap it claims fits a mini (72-83) is CA4313. Hope that helps. |

That's right if the overflow tank is pressurised. If the overflow is not pressurised, you still need a pressure cap on the radiator, but one which allows the fluid back into the radiator as it cools and contracts. |

Thanks for clearing that up for me SGC, I didn't realise that there were non pressurised tanks available. |

You can not buy a recovery type long neck cap... Best thing to do is to pull the radiator out and take to your local rad shop and have them fit a short neck to it. Mine needs to be done at the next engine out. Minimad |

Craig (Minimad) is correct. Dad took the radiator to the local Natrad and they said the same. I now have a short neck put on the top tank with a Commodore cap so it can be used with a non presurised overflow tank. If I want to use a Morris 1100/Moke etc etc brass presurised tank I can just chuck on a flat cap. 
Thanks for the replies |
