Among the frequent issues faced by car owners, leaking coolant ranks top on the list. As the fluid responsible for dissipating your engine’s temperature, coolant is essential for your vehicle’s optimal performance.
The coolant is transported via the radiator to the engine through an intricate hoses system to dissipate heat. In case of a leakage, the thermal load results in overheating your engine, exposing your vehicle to the risk of damage.
This article tackles various causes of coolant leaks and addresses the burning question: Can you drive a car with a coolant leak?
Where Does Engine Heat Originate From?
It is essential to understand an engine’s working to understand the effect of coolant leakages on your vehicle.
Internal combustion engines are among the popular engines on many cars. Fuel combustion occurs in the cylinder causing explosions that move the crankshaft. These explosions generate heat, which should be dissipated for optimal operation.
This is because internal combustion engines cannot convert heat energy to mechanical energy.
As a result, heat energy yields a high thermal load, which causes pre-ignition and loss of power. To maintain optimal operation temperatures, engines use coolant liquid run through channels in the engine.
The hot liquid is then transported to the radiator, where they lose the heat to the environment. The engine overheats may damage the water pump, the cylinder head, the connector rod, and the head gasket.
Can I Drive My Car Without Coolant?
While it is possible to drive some distance without coolant, cars will often succumb to overheating and stop operating.
This is because the thermal load will be so high for your engine, thus causing it to cut-out. Also, driving without coolant may result in damaged components, thus increasing the maintenance costs.
Can I Drive My Car With A Coolant Leakage?
However, it is possible to travel longer distances with leakage. For this, you need to stop regularly and refill your coolant. As such, this may prove costly for more massive leakages.
While vehicles can run for up to five minutes without coolant, there are several factors to consider. For instance, the terrain and temperature dictate how long your car can run with a faulty cooling system.
When navigating rugged terrain, the engine is exposed to excess stress, which causes it to heat-up faster. Likewise, the high thermal load on sunny days causes faster heating of your engine, thus limiting the distance you can travel.
Various car models, however, are fitted with a safe mode to manage coolant leakages. The cylinder banks allow you to travel an extra 200 miles, making it easy to reach a secure location.
Although it is possible to push your car to the limits, I advise against this as it may result in extensive damage and increase the repair cost. Also, ensure to address coolant leaks before they are severe.
Besides saving you money, they avoid extensive damage, including spoiling your water pump or the engine itself.
What Happens If You Run A Car Without Coolant?
Besides its capacity to damage components within your bonnet, a coolant leak makes it uncomfortable to drive your car. This is because the AC will not dissipate energy from the chamber, thus blowing hot air into the cabin.
As stated earlier, operating without coolant results in overheating of your engine. When you run your car without coolant, the first visible change will be the indicator on your dashboard. The temperature gauge will also be turned on to inform you of the spike of temperature in your bonnet.
Your car may also stop running by engaging the automatic cut-off placed to avoid damage to other components by an overheated engine. If your car lacks the auto-off feature, the heat may escalate to a point where steam starts emanating from your bonnet.
Additionally, overheating the engine causes poor fuel combustion, thus consuming more fuel per distance. As a result, running your car without coolant results in a high operation and maintenance cost and possibly forces you to perform an engine overhaul.
Signs Of A Coolant Leak
It is essential to identify a coolant leakage in its early stages to fix it before it damages various components in your vehicle. Among the signs of a coolant leakage include:
1. A Fragrance Is Originating From Your Engine.
When coolant liquid spills on the engine, it is combusted, creating fumes with an appealing scent. As such, you should stop your engine and trace the fumes’ source to recognize the source of leakages easily.
This may often be indicated by a stained spot on various components under your bonnet.
2. High Engine Temperature, Often Indicated By The Gauge On Your Dashboard.
Overheating of your engine is often caused by an inadequate supply of coolant to the system. Most times, the limited supply of coolant is a result of broken pipes or disconnected clamps.
3. Liquid Droplets Are Collecting Under Your Bonnet.
You may notice a puddle of green, pink, or blue fluid under your car in case of external coolant leakage. However, a clear liquid is not a reason to panic.
This is because a clear spill usually arises from the A/C as the gas condenses into liquid form. Upon noticing a colored spillage, consider inspecting its source or engaging professional assistance.
4. Internal Coolant Leaks
In various scenarios, you may realize a rapid decline in your coolant without spotting a leakage. This often implies a fault with your radiator or a damaged gasket kit.
When your gasket kit is broken, coolant mixes with your engine oil, causing a white residue. The white fumes from your exhaust can also help identify this error. The fumes are usually caused by burning and evaporation of the coolant in your oil.
5. Radiator Leakage
A worn-out or poorly fastened radiator cap may also result in coolant leakages. Owing to the engine cooling system’s pressure, the liquid may spill off, thus causing a drastic reduction of your coolant.
Alternatively, a radiator may have a burst, which drains the liquid. This is often indicated by bubbles within the radiator and requires professional assistance for replacement.
