Thanks, but How do you detect hairline cracks?

Aren't we supposed to have the pink SLL coolant? Why yours is greenish yellowish?

Plastic/rubber gasket would risk being sucked into the cylinders....

I replaced with Fel-Pro gaskets made of metal. They are highly recommended.

What causes bubbles in the coolant reservoir/tank when the car overheats?

Also, when the car overheats, the coolant reservoir/tank bobbles. Some say this is a sign of a bad head gasket or blown head gasket. But, I am puzzled because there are no other signs of blown head gasket such as oil on the oil stick nor is there oil on the engine oil cap. There is NO smoke from the tail pipe, nor steam, nor water. the radiator cap has been replaced twice and the radiator has been replaced also. The thermostat is new as well.
