What does it mean when your car heater core is leaking?
If your windows are fogging, it means the feed pipe is leaking. It could also mean that the small pipings in the heater core have a leak. Instead of hot air blowing into the cabin, the hot coolant leaks and evaporates into steam. The cool air in the car condenses the hot coolant. This is how your windows become fogged out.
Can a bad blower motor indicate a bad heater core?
It may indicate that your blower motor or another component of your heater has gone bad (cheer up, it may be a component that’s less tedious to fix than the heater core). Though, if you’re seeing one of the other signs in addition to a lack of heat that’s a pretty good indicator that the heater core itself has a problem.
What happens when a heater core goes bad?
A heater core often goes bad due to leaking. As the heater core uses engine coolant to generate heat, a leaking heater core will reduce the amount of coolant in the cooling system. Low coolant will cause an engine to run at a higher temperature, which can result in extensive engine damage. Can a Bad Heater Core Cause Overheating?
How is the heater core connected to the engine?
As said earlier, the heater core connects to the engine by two pipes – feed pipe and return pipe. Hot coolant flows from the engine via the feed pipe into the heater core. If your windows are fogging, it means the feed pipe is leaking. It could also mean that the small pipings in the heater core have a leak.

Can a bad heater core cause engine damage?
A low coolant level (caused by a leaking heater core) can lead to overheating and possible engine damage. Even a clogged heater core has the potential to obstruct coolant flow enough to cause overheating. A low coolant level (caused by a leaking heater core) can lead to overheating and possible engine damage.
What should I do if my heater core is too hot?
Set the heater to the MAX heat position. Check the temperature of the heater core hoses: Both hoses should be too hot to hold. Typically, the inlet hose should be about 20 degrees warmer than the outlet hose. If the outlet heater hose is significantly cooler than the inlet hose, the heater core is probably clogged.

Where is the heater core in a car?
As said earlier, the location of the heater core is behind the dashboard on the passenger side. If your heater core is leaking coolant, that means the coolant level is low. As such, the engine can overheat. This is one of the main causes of mechanical breakdown.
When do you Know Your heater core is bad?
Though, if you’re seeing one of the other signs in addition to a lack of heat that’s a pretty good indicator that the heater core itself has a problem. When a hole or puncture develops in your heater core, all that warm air may escape too quickly to reach you at the other end of the heater ducts.
Why is my heater core gurgling and hissing?
This usually means that there is air trapped in the coolant that circulates through the core. This can happen for a number of reasons, including a blown head gasket or a leak developing in the heater control valve. You’ll need to diagnose and fix the cause before you remove the air and replace the coolant.
Can a car heater core leak into the cabin?
Even if you have an older vehicle with the heater core outside the cabin, leaking fluid can still find its way into the cabin through the ventilation ducts. Having coolant leaking into the cabin of your vehicle can cause all sorts of problems.
What does it mean when your heater core is leaking?
Having a leaking heater core can be one of the most frustrating leaks you can have in your vehicle. Almost any leak in your car is an external leak, meaning the leaking fluid will just leak out onto the ground.
How can you tell if your car heater core is bad?
The antifreeze or coolant is the main ingredient that keeps your coolant system and car cool. If the odor is strong inside the passenger compartment, it’s a sign you have a bad heater core. Antifreeze contains ethylene glycol. This is a toxic substance and what makes the coolant have a sweet and fruity smell.
What should I do if my air conditioner core is failing?
The heater hoses should be inspected when replacing a heater core. Problems with the heater hoses can cause similar problems to a failing heater core and are less expensive to correct. Some cars will need to have the air conditioning system recharged, which can increase the cost of repair.
