And put some in the expansion tank.
Then run the motor, get it hot.
It should puke coolant into the expansion tank, let the motor cool down and it´ll suck back into the radiator what it needs.
Keep the expansion tank about half full.

Hi folks ..my 77 305 has a dual core rad.....I've only had the car a couple weeks...I noticed the expansion tank is empty and doesn't appear to fill with any coolant...should I be concerned?...as no probs on the road..and the temp warning gauge works and has never come on....also I've noticed the level in the radiator was down a few cores...so I topped up but not so covering all of them...there's no "max" mark on the casing so am I right in thinking that it just settles to a certain level which is normal for my particular car? |

There should always be some coolant in the expansion tank, never dry. Mine´s marked at half full for cold, engine hot the level rises a little. My rad is full to the brim. |

Second that on the coolant reservoir  They are designed as closed loop, you can get the reservoirs new from the U.S which is good news. |

Thanks I'd thought about filling the expansion tank......i brimmed the radiator today before going for a city center drive.....no probs during it.......i checked for leaks and none seen....the inlet and outlet hoses were warm too....so the system works.

You should´nt have to take the cap off the rad., just check the expansion tank and top that up. |
