If it looks like a hose is leaking near a clamp, try tightening the clamp with a screwdriver.
Does a cracked block leak antifreeze?
A crack in the engine block can cause antifreeze to leak from it, which puts your car at risk of overheating due to the lack of coolant. The most common sign of overheating is a rising temperature gauge and white smoke coming from under the hood.

Why is my car going through coolant quickly?
This can be caused by a number of things such as low coolant levels, a faulty thermostat, a clogged radiator or a failing coolant fan switch. In addition to leaking around the pump, you may have a leak elsewhere in the cooling system coming from one of the hoses going to or from the radiator.
Can you drive with a coolant leak?
Driving with a radiator leak is a dangerous operation, as it will very likely cause your engine to overheat. If you are driving down the road and notice your engine is overheating, pull over immediately and let the vehicle cool down.

What’s the difference between blown head gasket and cracked block?
a blown head gasket is when the material between the block and the cylinder head is damaged or otherwise leaking enough to allow cross contamination between oil, coolant and the environment. A cracked block is actually broken metal through which liquid or gas can escape.
Will an engine run with a cracked block?
A cracked engine block can result in low engine compression if the crack is severe enough and/or deep enough within the engine block to pierce any one of the engine cylinders. At this point, normal engine combustion pressure is disrupted, which in turn, lowers engine compression and results in poor engine performance.
Is it cheaper to replace a head gasket or replace engine?
Changing the engine generally will cost a ton more money than simply replacing the head gasket. So, unless your cylinder head is damaged beyond repair, and you won’t know that without stripping the cylinder head. Replacing the gasket is the most cost effective route.
