How To Check And Maintain Coolant Levels Properly
Coolant acts essentially as a heat transfer fluid in the engine of your vehicle. It absorbs the extra heat created
during combustion in the cylinder and distributes it to the entire cooling system so that the engine can work
efficiently and safely. Proper coolant level maintenance is a plus for engine health; too low or insufficient coolant
leads to overheating that damages engine components severely, diminishes performance, and is subject to expensive
repairs.
In this article, we'll guide you to what coolant is, why it's important, how to measure coolant levels, and how to
maintain them properly.
What is Coolant and Why is it Important?
Coolant, which acts as an antifreeze, is a liquid mixture of water and chemicals that regulates your engine’s temperature. It consists of a mixture of water and ethylene glycol or propylene glycol, which lowers the freezing point and raises the boiling point of the fluid. It:- It prevents overheating by absorbing engine heat.
- In winter, it prevents the freezing of the coolant.
- Prevents corrosion in your engine and radiator.
- Increases performance with a consistent temperature.
Signs of Low Coolant Levels
Before we get into how to inspect the coolant, let's check out some signs of low coolant levels:- Always runs hot on the temperature gauge.
- Sweet odour (usually this means that there is a leak).
- White smoke is coming out of the exhaust.
- Puddles out of your car; these puddles can be green or orange, or even pink.
- Warning lights on the dashboard.
- If you ever observe any of these signs, start checking the coolant immediately.
How to Check Coolant Levels Properly
Having your coolant levels inspected is an easy but important preventive maintenance operation. Here's how you can go about it.Step 1: Park Safely
Coolant checks must always be done with the vehicle parked on a level surface. Let the engine cool completely, or you might get burned by hot coolant or steam.Step 2: Find the Coolant Reservoir
Open your hood. Locate a translucent plastic tank with engine coolant marked on it.Step 3: Check the coolant Level
The reservoir should have a level between the "MIN" and "MAX" marks, and if below the MIN line, top it up, and if above the MAX line, drain it.Step 4: Check Coolant Quality
Check the coolant quality via colour. Coolant should be bright and clean (green, orange, or pink, depending on the type). Read more about: Role of Engine Coolants in Your CarHow to Maintain Coolant Levels
Monitoring Coolant Oil is half the battle; regular maintenance is what ensures optimum performance through time. Let us see what you should do to keep your cooling system at top performance:1. Topping Up for Coolant
Use the coolant recommended by your car's manufacturer. Mix the coolant with distilled water (commonly in a 50:50 ratio) unless you are using a ready-to-use/premixed solution. Pour slowly into the reservoir until just reaching the MAX line.2. Check for Leaks Regularly
Check for coolant leaks beneath and around your car's engine bay. Tiny leaks, even though very subtle, can grossly reduce coolant levels with time.3. Have the System Flushed
Coolant ceases to be effective with time. Thus, the best time to flush any car's coolant is typically every 30,000-50,000 miles or 2-3 years, which washes away the old coolant and debris.4. Track the Temperature Gauge
Keep an eye on it from your dashboard. If it gradually moves up the dial, then your coolant system is eminently due for checking.5. Replace Worn-out Items
The hoses, clamps, and radiator can wear out. Check for these items during routine maintenance to avoid leaks.Mistakes to Avoid When Checking Coolant Levels
Never ever open the radiator cap when the engine is hot because boiling water and steam could shoot out and cause serious burns. Intermixing various types of coolants: Always maintain one type (e.g., OAT, HOAT, IAT). Mixing lowers efficiency. Discoloured coolant: Rusty or hazy coolant indicates contamination. Overfilling the reservoir: Excess coolant may lead to overflow and pressure problems.Advantages of Having Proper Coolant Levels
Having proper coolant levels has several benefits:- Longer engine life.
- Improved fuel efficiency.
- Less repair bills.
- A consistent performance in all weather.
- Improved vehicle safety.
