They are mostly found in European cars. A faulty EGR cooler will cause the coolant to leak into the exhaust pipe, which will also cause white smoke from the exhaust pipe.

Certified Automotive Diagnostic Technician. On Saab , I got the low coolant warning on a trip and topped up with just a little bottled water seemly no big deal. Eleven days later and 5 days before my Saab service shop can see the problem , my reservoir is half empty. My question is: to avoid mixing different coolants, is it okay to use distilled water to get the car through the next few days? I need to drive it three short distances before having the coolant issue resolved at the Saab service shop.
Ha e ods Auroa says low cooling just had mechaninc replace thermostat also new Water pump problem is that saing low cooliant on dash board. But needle says ok is normal could just be ediot lnothis normal.

Symptoms of Low Engine Coolant 1. Low engine coolant symbol on dashboard. Fluctuating temperature gauge. Rising temperature gauge. Heater not working. The sweet smell of anti-freeze. Causes of Low Engine Coolant Level 1. External coolant leak. Faulty intake manifold gasket. Faulty head gasket. Faulty radiator cap. Faulty EGR cooler.
Still have questions? This is is a common problem in cars that make use of normal tap water without an anti-freeze. To avoid this problem, you should have a ratio between the coolant and water. If low engine coolant is left unchecked for long, it will cause the engine to start overheating. This will lead t increase in temperatures on various engine hot spots. More coolant will get into the engine system because of the leaking head gasket. When this happens, it will affect the power of the vehicle because the coolant will go into the combustion chamber, thereby completely destroying the engine.

A blown head gasket can be identified by checking the end of the oil dipstick. If you see milky liquid or bubbles, it means the gasket has really blown. Ensure you have your mechanic check and rectify the issue immediately. Most engine parts are produced from metal.
The anti-freeze contains chemical compounds that helps protect components of the engine from rust. These components become exposed and vulnerable to corrosion and rusting if coolant is low. The coolant is important in cooling the engine of your car. The fuel and air mixture produces a lot of heat which has to be dissipated.
Low engine coolant may be caused by leaking hosepipes, leaking gasket, faulty radiator cap, faulty heater, and overflow reservoir. Now you know all about low coolant in the car and the signs that accompany this condition. It is not advisable to drive or run your car with low coolant because it can lead to damage to your engine. The radiator cap is released by the pressure, sending the coolant towards the overflow tank.
If the radiator cap is damaged, the coolant will be released too early, and cause the reservoir to overflow. A faulty radiator cap can cause the overflowing reservoir, turning on the low coolant light. Fix: if you think you can confidently work on your car for repairs, then you can replace the bad cap with a new one. If you do this yourself, make sure the engine is completely cool and get the correct replacement cap. The radiator hoses in your vehicle are constantly exposed to hot coolant when your engine is running.
These hoses will break-down over time due to the elements they are exposed to. They might even crack or burst, causing coolant to escape and prompt the low coolant level warning light to come on your dashboard. If your radiator hoses are damaged, the low coolant level light in your car will turn on. Fix: First, you need to park your vehicle over a dry and even surface. Let your car run until it is warm, and then let it sit overnight Check for any coolant leaks in the morning, seeing if there is any liquid or oil on the ground.
Feel the sides of your radiator hoses for any damage or leaks. If the radiator cap and the radiator hoses are not damaged, then there might be a faulty radiator, water pump, or thermostat housing. Damage to any of these parts will cause your low coolant light to come on. The radiator is in charge of passing your coolant through metal fins, wallowing the heat to flow to the air outside of your car, preventing overheating. The cost varies depending on the labor involved and the model of your car.
The water pump is a mechanism that ensures the coolant moves through the engine block hoses, and radiator. The pump in charge of the system is working at the correct temperature. Fix: If you suspect that one of these two mechanisms might be the real issue with your car, then you need to get your car to a mechanic as soon as possible. These repairs typically require the mechanic draining the coolant, and replacing the defective component, being either the water hose or the radiator.
The mechanic will then refill the coolant to fix the low coolant level. Your head gasket is in charge of providing a seal between engine block and cylinder. In addition, it lets the flow of both oil and coolant pass smoothly.
If the head gasket has failed, it can cause the coolant to be burned in your combustion chambers — this is dangerous, because you might not see any leaks happening. The burning of the coolant within the combustion chambers can cause the low coolant warning light to come on.
