Radiator Cap on 89 SP 36'
The other day I had the fill cap neck of the coolant fill tube fixed. It had
a bad spot in the lower ring that would let the coolant buy to the over flow. It had been brazed before & it looked like it had been done at the factory as it didn't look like it had been taken out before. I took it to a rad shop & had a new neck put in. It cost a whole five dollars to have done but then I have given this shop two rad jobs in the last couple years. My question is the old cap had a rubber seal on the bottom & a brass on top and the new one I bought form NAPA had a rubber seal on the top & bottom. They are both 7# so they are the same pressure. What is the differences between them? The new one looks like it would not let any coolant out of the top& it fits a lot tighter. The generator hat the same 7# cap on it with rubber only on the bottom so I don't think they had been changed. Which is the best cap?

iwould say that the old one is an open system cap any leakage or
expansion goes to atmosphere or overflow the new cap would allow expansion only outof the overflow(closed system cap) siutable for use with expansion bottle Stephen 77fc35 --- In WanderlodgeForum@yahoogroups.com, dspithaler@a... wrote: > The other day I had the fill cap neck of the coolant fill tube fixed.
