What to do if you think your car is leaking coolant?
If you think there is a leak in your engine, you need to find out where the leak is coming from. This leak could be an internal or external leak. You need to search under your car to see if you can notice any external leaks. If you don’t find one, then search under the hood for an internal leak.
How can I find out if my cooling system is leaking?
The common trouble spots in the cooling system — the places where you should check for coolant leaks— are shown here. Check for cooling system leaks and other problems. Look under your vehicle: Look under your vehicle in the morning, when the vehicle is nice and cool, to see if there’s any liquid on the ground below the under-the-hood area.
What happens if coolant leaks from the radiator?
This sediment could plug the system and eventually cause leaks. Any type of leak within this system could seriously damage the engine. If coolant leaks into the engine, you need to stop driving your car immediately and get the leak repaired. Did you know that a leaking radiator is the leading cause of overheated engines?
Can a crack in the head gasket cause a coolant leak?
This is a sign of a coolant leak, but might also be caused by cracks in the engine, head, or head gasket. The most obvious coolant leak solution is to find and fix the leak, but finding the leak is not always an easy task. Here are some of the most common ways causes of a coolant leak and how to fix them.
How much does it cost to repair a coolant leak?
Leaks are able to occur anywhere the refrigerant passes from part to another. If it isn’t a leak, the common repair can be anywhere from as little as $300 to more than $2,000. Recharging the old refrigerant is one of the most common repairs and can cost $95 to $255.
Is leaking coolant an expensive fix?
If coolant is leaking inside your car, then the repair can be expensive as the heater core must be replaced and those are difficult to get to which requires more labor. If coolant is leaking inside your engine because of a blown head gasket or cracked block, then the repair will be quite expensive.
How do you repair a coolant leak?

Can you lose coolant without having a leak?
When you are losing coolant but no leak is visible, several parts could be the guilty party. It could be a blown head gasket, a fractured cylinder head, damaged cylinder bores, or a manifold leak . It could also be a hydraulic lock. If the antifreeze vanishes without any apparent reason, check these components for cracks, damage, or defects.
Why do I have a leak in my coolant reservoir?
But if you’re refilling the coolant reservoir or radiator frequently, most likely the engine cooling system has a leak somewhere. Some leaks will form a narrow stream of coolant you can’t miss. But small leaks and internal ones, especially, make troubleshooting tricky. Either way, you’re in a race against time.
Can a bad coolant sensor cause a car to not start?
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.
What does it mean when your coolant level is low?
A low coolant level doesn’t necessarily mean a coolant leak. But if you’re refilling the coolant reservoir or radiator frequently, most likely the engine cooling system has a leak somewhere.
What should I do if I have a coolant leak?
The pressure of too much coolant could cause the radiator to start leaking. If you notice a leak, you should check the level of your radiator and the strength of your coolant. Always make sure you check your radiator when your engine is cool.
What causes a radiator to start leaking coolant?
This happens because radiators and hose connections all collect sediment over time and then they start to rust. This rust creates holes throughout the radiator. Another way the radiator could leak is by over-filling it. The pressure of too much coolant could cause the radiator to start leaking.
What happens if you lose antifreeze with no apparent leak?
Losing Antifreeze With No Apparent Leak. Whenever a vehicle loses antifreeze, also known as coolant, the usual expectation leads the owner to check for evidence of leaks at all the coolant connections and components. Obvious coolant leaks can usually be found in the form of puddles left on the pavement.
What to do if your coolant system wont hold pressure?
Check to see if your coolant is discolered or has any particles floating around in it. Then check your oil and see if it is over limit or smells like coolant. If so it is probably your head gasket. especially since you have changed the thermostat already.
Can a coolant leak cause a puddle under the car?
However, if you have performed a thorough assessment and found nothing wrong with the external car coolant system, then you’re most likely dealing with an internal leak. Internal car coolant leaks do not produce a puddle of coolant right under the vehicle as what you would normally see in an external coolant leak.
Can a blown head gasket cause coolant to leak?
If the head gasket fails, coolant, and engine oil may mix. You may also notice that coolant is leaking from the bottom of the engine and dripping onto the ground. Either way, a blown head gasket can be disastrous for your engine.

Is it normal for coolant to leak from Radiator?
If your vehicle’s radiator has one, you may notice a leak in front of your engine. Coolant leaks are serious business any time of the year. That is, even though coolant is commonly called antifreeze, it is essential year-round. Therefore, if you have a car leaking coolant, you must take the leak seriously.
Can a car lose antifreeze without a leak?
Monitoring its level and condition is a part of the regular maintenance of the vehicle. Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze. However, a car could be losing coolant but no leak. What should you do when coolant disappearing from reservoir without leaving any trace?

Where does the coolant go in a car?
If you still can’t find anything or the pressure does not drop, then there probably is not an external leak. Another important thing to remember is that the coolant system goes into the car’s cabin. This means that it could leak from the heater. Check to see if the floor mat in your car is dry.
Why is coolant leaking from the intake manifold?
If the coolant is leaking from the exhaust or the intake manifold, a blown gasket head could be the reason. One should know that treating head gasket leaks should be a priority as they may expand over time.
Can a blown head gasket cause a coolant leak?
Blown Head Gasket The car’s head gasket is responsible for keeping the engine oil and coolant separate. When the gasket first fails, you may not even know what’s happening because the leakage can be internal. However, you might start to notice coolant in the engine oil or vice versa.
What should I do if my coolant is leaking?
The coolant leak will need to have the cooling system pressure tested to see if a hose or component is leaking in the rear heater system. If you lose all the coolant, the engine will overheat and can cause engine damage. Have the coolant leak repaired as soon as possible.
If the head gasket fails, coolant, and engine oil may mix. You may also notice that coolant is leaking from the bottom of the engine and dripping onto the ground. Either way, a blown head gasket can be disastrous for your engine.
What happens if coolant leaks from the bottom of a radiator?
The radiator is a pressurized system so if there is a loss of pressure from the cap not fitting properly or if the cap is the incorrect cap for the radiator, the pressure will be lost and a leak could occur. This can be diagnosed with a pressure test of the radiator cap.
Is it possible to smell a coolant leak?
You may even be able to smell the coolant leaking. Oftentimes, the type of leak is easy to determine but sometimes it takes a little more effort to find it. It is a good idea to check the level of the coolant reservoir tank with every few gas fill-ups. Below are the common causes to your coolant leaks:
