I have changed the radiator cap yesterday and filled up the radiator for about 18oZ of antifreeze, this morning, I've added another about 15oZ to the radiator and it's seem OK. The fans did not run when it was showing hot temp. The only antifreeze spilled was from the overoverflow.I'll keep checking on it for couples of days to see how it does.overflow.

Don't let the engine overheat, this will damage the engine. If the engine is getting too hot the radiator cap will relieve the excessive pressure and coolant will escape from the reservoir, which is what it sounds like is happening. Have the cooling fan system checked out, and the cooling system for proper operation.
