Title: Expansion tank cap pressure
Post by: HFStuart on March 22, 2011, 08:59:56 AM

Does anyone know the correct pressure rating for the expansion tank cap? I've got conflicting information from internet and Mr Haynes...

Thanks,

7 psi seems to stick in my mind.

couldn't find it in the official manual found this

kuhlerverschluss-uberdruckventil offnungsdruck 0.78 bar
prufdruck zur kuhlerdichtheit                          1.00 bar

in verlag workshop manual but I don't understand German so I'm not sure if it's the right info

just a comment and a personal opinion but on the whole I wouldn't rely too much on haynes better to get hold of a pucka Lancia issued workshop manual plus the latest update of the technical databook that you can find (and the later style short manual if you have an injection car)

Great - I couldn't find that in my UK manual.

Loosly translated - Cap opening pressure 0.78bar, cooling system test pressure 1.00 bar

Thanks,
