I replaced my rad cap with a new one that I purchased in my local Alfa Romeo dealer and it has finaly done the trick. It is from an Alfa 33 and the part # is 60561208, the cost was $16. The coolant is now at the correct level and no more coolant loss
BTW Brian, what year did they replace the caps with the 16psi version ?

The factory upgraded all radiator caps from 13psi to 16 psi for that reason. |

You guys have nailed it! My '89 328 dribbled, and I bled the air from the radiator, and it dribbled, and I reasoned out the problem, and it dribbled, and I replaced the expansion tank, and it dribbled, and yes David, it gave me fits...
Then, I replaced the cap with a cheap Standt 229, then a #330, let the car find it's equilibrium, and no more dribbling. Do you think there is air in the top of my radiator? You bet there is! And if I bleed it down, add a little coolent to compensate, you know what will happen.
Don't worry about the 1 or 2 drops you occasionally see after a long drive. Most of the 3.2's do it. It is the nature of the beast.
You guys are great! |

Mine (328) dribbles if I fill it to recommended level. So I don't. Mine has no warning light, however. And mine accumulates air at radiator. I bleed it every so often. Always has done that, always will I imagine. I think it is the nature of the beast. |

Dave H.: "Quit topping it off and let it spit/puke whatever until it reaches some sort of equilibrium. Then leave it alone, until you have some sort of problem. Messing with this stuff too much will just give you fits....."
EXACTLY! I went throught with this, this past winter and a few times this summer and it was non-stop (leaving big puddles). I was fed up of topping it off and then it stopped! Its lower than the requested 6cm, but my car drives around at 175-185°F and not a drop. Whatever difference made by a few cm's less coolant is only a fraction of the 24 litres of coolant that I ended up pouring into my car (and that's alot of coolant to cool a small motor like this...). |

Ferrari radiator caps are crap. I'll bet if you go to NAPA with the cap and get a replacement, the dribbling will disappear.

Well, the coolant level is down to about 3.25" from the reservoir cap and it stopped puking--I guess this must be my car's comfort zone. It's a bit lower than what the manual suggests, but the temp is good. I'll keep an eye on it and will likely replace the cap just on principle anyway. Thanks for the input, comrades. |

Have you got the correct pressure radiator cap on or perhaps the tension has become weak or the rubber seal has hardened? |

Hi David,
I did that for a week or two but the coolant level warning light kept coming on, on the center console and the level was below the recommended 6cm.
I have replaced my radiator thermoswitch (with one from a VW dealer, last week as the fans were not kicking in) and this seems to have eliminated the frothing issue and the car stopped putting out a lot of coolant. That being said it did still put out coolant, albeit a lot less.
I then left the heating system in the ON position constantly with the fan rheostat turned right down so as not to melt while driving. Then, the morning after I have been out in the car (i.e. when it has cooled down) I bled the radiator. I think it is working because it has not dumped any coolant for over a week. Initialy there was air coming from the rad bleed screw every morning but now I get no air at all. Fingers crossed, so far so good. |

if you are standing behind the car, the bleed "screw" is below you cold start injector, o on the passenger side, sitting above you water pump. It is actually a bolt, I forget the size, not a screw like on the radiator. |

Each time i take my car ( which I've owned for a month ) for a drive, I 've noticed about a drop or two of coolant coming from the overflow hose of the reserve tank once the car is parked. More recently, on very hot days, there was a lot more coolant /mixed with a whitish ,bubbly froth being puked out. I've kept the level of coolant at between 2"-3" from the reserve tank cap, as directed in the manual. Upon bleeding via the radiator bleed screw, a great deal of air/ bubbles are emitted. Any thoughts on this?
I noticed in other threads on bleeding the system, someone stated that there is also a bleed screw on the thermostat housing. I don't see any other such screw on my car ( an '85). Am I looking in the wrong place or is there just one screw on '85's? |
