No the cap is vented and push any unwanted coolant out
I don't think you can actually overfill a car with antifreeze. There is an overflow chamber that prevents this. Perhaps this overflow can be overfilled but in that case the worst thing that can happen is the little plastic cover pops off and you get some excess antifreeze on the ground. It might also depend on the car. when car gets hot it will push coolant to reservoir (expansion) and when cold, into radiator. this is the function of the rad. cap....if u overfill reservoir it will only leak out of fill cap to the grd
Correct coolant level for the 306 is about 4 inches below the top of the radiator. If it is filled any higher the car will blow out the excess DO NOT OVERFILL
When the car is cold the thermostat is closed. When the thermostat is closed the coolant does not circulate or get in to the engine block.
Just pour it into the coolant tank. Don't overfill, use 50% water and get an extra 15lb coolant tank cap.
After coolant is added run vehicle to normal operating temperature and re-check coolant level
You start to lose compression and coolant is in your oil
The car normally pushes it out the over flow.
When you overfill oil in a lawnmower it will smoke when you tip it sideways while mowing,it has no harm
a big mess.
The engine of your car will heat up.
The coolant add/overfill jug is on the left side of the motor when your looking at it. Add coolant up the closest line towards the top, and only when the engine is cold.
