How do I know if I need a coolant flush?
If you find that your temperature gauge is always high and your engine is frequently overheating, chances are that you need a coolant flush. Allowing your engine to overheat can cause serious, costly problems, so it is best to visit a mechanic at the first signs of temperature issues.
How often should a coolant flush be done?
The simplest way to avoid overheating is to service the system every two years or according to your car manual recommendations. Flushing the coolant and replacing it with fresh fluid every two years or 30,000 miles is a good rule.
Does coolant flush help AC?
Your A/C system uses a type of refrigerant (commonly called Freon) to cool the interior of your vehicle. Having a coolant flush performed will not help your A/C stay cool, or visa versa.
Can I do a coolant flush myself?
Remove the radiator cap and pour distilled water into the radiator until full. Replace the cap, then start up the vehicle and let it run for 10 to 15 minutes. This will work the distilled water into the engine, flushing out any loose debris or corrosion along with the last of the old antifreeze.
Does coolant affect AC?
Yes, coolant can affect a car's air conditioning by impacting the car's temperature, humidity, and airflow.
What does a coolant flush consist of?
A coolant flush resolves this problem – it's basically a blood transfusion for your cooling system. A flush involves forcing several gallons of cleaner, water and new antifreeze through the system to get rid of all the old antifreeze and the contaminants that may have built up in it.
Does coolant flush help thermostat?
No, it is not necessary to remove the thermostat. In fact, some cars you don't want to remove the thermostat while running the vehicle. The reason for this is that the thermostat can be used to direct coolant flow. If it is out, parts of the engine may not be getting coolant as designed.
Will a coolant flush fix a thermostat?
Doing a radiator flush does not require any other component to be replaced. However, if the system has a lot of debris and scale in it, the thermostat may need to be replaced if it gets clogged or corroded.

Is coolant the same as antifreeze?
Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it's important to know what variety is right for your car or truck.
Can I use water instead of coolant?
Water by itself can't do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle's engine. Plus, it doesn't absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
Does coolant affect car heater?
Low Coolant Level The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car.
How can I make my car AC colder again?
Leave the A/C button off at first. Turn the fan to its maximum speed and make sure the airflow is set to "outside" mode. Then, once you've forced out some of the humid, hot air that's accumulated in the car, turn on the A/C and switch to "recirculate" airflow mode.
How often should you change engine coolant?
HOW OFTEN SHOULD YOU FLUSH THE COOLANT? Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant. You can tell which type of coolant you have by the color.
Why is my coolant reservoir always empty?
Disappearing engine coolant could be the result of a slightly cracked hose, a tiny hole in your radiator, or a water pump issue. It's also possible for a coolant leak to develop inside your vehicle or to simply vaporize into mist via your defroster.

Can I top up coolant with tap water?
No, you should use distilled water or better yet, de-ionized water. The reason for this is that tap water has minerals that can deform deposits inside the radiator and the cooling system passages of your engine.
What happens if I add water to 50/50 coolant?
While you can drive the car for a short time using water in place of the coolant, it won't effectively protect your engine. This means its essential to get the problem that caused a low coolant level fixed as soon as possible, and the radiator filled with a 50/50 ratio of coolant to water.
What color should antifreeze be?
Fresh antifreeze is a clear brightly coloured liquid, usually blue, red, green, violet, yellow or orange but this will vary depending on the manufacturer's formulation. Over time, your coolant will become dirty losing its colour and becoming darker, often an oxidized shade of brown.
Why is the heat in my car not very warm?
You might ask, “Why is my car heater not getting hot enough?” Common causes are thermostat problems, heater core issues, jammed heater flaps, air bubbles, and low coolant levels. Some of these reasons are partly due to the age of your vehicle, while others are a result of poor vehicle maintenance.
What happens during a coolant flush?
Cleaning Out Debris: Coolant flushes are able to get rid of all of the sludge, scale, rust and other debris that may have built up in your coolant system overtime. All of these reduce the performance of your cooling and can potentially cause damage in the various parts of your cooling system.
What is the purpose of a radiator flush?
The coolant keeps your engine from overheating while running, and from freezing in cold weather when it’s not running.
