A head gasket leaking external would cause coolant to come from below the intake or exhaust manifold and often only happens when the engine is completely warmed up.
What should the temperature be in a blown head gasket?
The failure of a head gasket is sometimes due to limitations in the vehicle’s engine design. Consequently, maintenance of the cooling system with quality fluid and top-ups is evermore essential in today’s cars. In modern engines, normal temperature levels place in the range of 200 to 225 °F.
How much does it cost to repair a blown head gasket?

If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
Can a faulty intake manifold cause engine overheating?

Why does a blown head gasket cause overheating?
Your head gasket is an important component in your cooling system. It not only creates a seal between your engine block and head, it also channels coolant for optimal engine cooling. A blown head gasket can allow coolant to either enter your engine, where it is burnt off or leaks out…
Where does the coolant go after blowing the head gasket?
Coolant either leaks past the head gasket out of the engine or past the head gasket into the cylinder and combustion chamber. If you have an external leak you will notice coolant leaking from in between your engine block and the head. This usually will happen just below the exhaust manifold or the intake manifold.

Can a crack in a head gasket be fixed?
Cracking can rarely be fixed and can be difficult to find with a simple visual inspection. Tunneling can happen when coolant leaks through to a cylinder for a long time and erodes the metal on the head. This can sometimes be fixed by welding new metal on but often means the head casting is ruined.
Is it better to replace head gasket or replace whole engine?
If your head gasket leak has caused this problem you are almost always better off replacing the whole engine as a new head gasket will stop the leak but bearing damage has probably already been done.
