Can a leak cause a car to overheat?
Once the radiator extracts the heat from the coolant, the coolant circulates back to the engine and the cycle starts again. Therefore, problems with a water pump, such as a leak, could cause an engine to overheat.
Why does coolant leaks can cause the engine to overheat?
If it develops a leak from wear over time, it’s called a blown head gasket. When this happens, your engine oil and coolant will be able to mix, causing difficulty keeping your engine running. This can also lead to coolant leaking outside of your engine and cooling system, which can cause your engine to overheat.
Why is my car overheating with no leaks?
If there’s no leak, an overheat is caused by a problem with coolant level, coolant circulation, or heat transfer. Fill the coolant level. If the problem recurs within a month, it was something other than low level. Circulation problems are caused by clogged radiators, bad water pumps, non-functioning thermostats.
Can a low coolant leak cause an engine to overheat?

What causes an engine to overheat with a water pump leak?
Any leak in the system will reduce the coolant level and pressure within the system resulting in a reduced capacity for coolant flow. If the coolant cannot circulate to do its job, then overheating will inevitably occur. There are many points at which a leak is likely including hoses, radiator, water pump or head gasket.
Can a blown head gasket cause an engine to overheat?
