I have a 1995 Integra. And for some reason my antifreeze container always overflow, and boils. The guys at the dealership at first said it was the radiator. But i had a brand new one put in about 2-4 weeks ago. And it still has the same problem. Also my Engine Temperature gauge instide the car goes way past the limit too. The engine doesnt seem to be burning. If this occurs and i take the oil cap off, white smoke comes out of it. Does anybody have a solution to these problems? If so please write back. All suggestions welcome

Thank you for your time

 

When was your thermostat last replaced?

If it is failing to fully open, you could be overheating the car despite having a fully operational radiator, which would cause coolant to flow into the overfill bottle.

 

Boiling coolant means that it's either not holding pressure (higher pressure raises the boiling point), or it means that there isn't much coolant in there, i.e. it's mostly water, or it could be both of those.

 

Just to throw this in here...driving your car to the point where it constantly overheats is not a good idea...

 

i run almost all water and i never over heat but check ur cap and thermostat
