| Post subject: | Radiator Cap Pressure?? |
Can someone tell me what pressure a radiator cap should be.. Says in the book 13psi (89kPa) for "All except late UK models" or 15psi (103kPa) for "Late UK models" |

Stick to 13psi I think most people will say. I think that's what I have on mine. |

13 for my K. I bought a new cap, after running an old one from my clubby, and the new 13 one is right on the money. |

Although, I was just thinking... In Aus, our cars obviously get hotter than they do in England. Would a 15psi cap not suit our cars better? The water in our cooling systems has a tendency to get hotter, so would it not be better to pressurise the system a touch more to increase the boiling point, hence less likely to boil on a hot day? Hmmmm.... Wait for a pro to answer this one... |

The cap you have shown is off the radiator, and it does not pressurise the system. The Pressured cap will rather be on the overflow tank. this keeps the rad full, and the overflow tank at a varying level istead. This just means that the rad never loses coolant below the full level. |

| That's not the right one...
There should be a rubber piece with a spring. As far as I know there are 2 types for australia, "long" spring version for later radiators for clubbies etc and earlier "short" spring version for earlier models. The spring length corresponds to the radiator neck length (the bit that the radiator cap screws on to). The rubber bit on the spring should be just abit longer than the radiator neck to form a pressure seal on the inner lip of the neck of the radiator... |

DONT mix up the long and short ....DOUBLE-CHECK that the parts guy gives you the right one..... I run a Minispares 4-core and it uses the SHORT cap ... NOT the long one ... (its only 1/4" difference) you'll have endless fun if you put the wrong one on .... like 2 impromptu side of the road lower-radiator hose changes, a welsh plug change and an upper radiator hose change . . . . its a Looooong way from goulburn to gosford. . . . .

Trevors radiator is under a lot of pressure too. He has to perform well at everthing Poor Trevor. One day. |
