Here are some more information for Radiator Coolant:

1) The oil gauge

On the dash board of almost every passenger car you will find an instrument which is marked oil. Most drivers misunderstand the meaning of this instrument and that could end up costing you thousands of dollars on a replacement engine. The oil gauge is not an oil level indicator, which most people believe it to be, but instead is an oil pressure gauge. The purpose of this instrument is to monitor the oil pressure inside the engine and to alert you to a drop in pressure which is a sign of internal engine damage or wear. This gauge is not a replacement for regular oil level monitoring done by checking the oil level dipstick in the engine compartment. Many people unknowingly assume this oil gauge will inform when the engine is becoming low on oil. This is one of the most common causes for seized engines as the oil pressure can be good even if the engine is almost completely empty of oil. By the time the oil pressure gauge reflects a low reading it is likely that internal engine damage has already happened. Check your oil level regularly, and more in older or high mileage engines to avoid a premature engine failure.

2) Overheated engines

When a car leaks or burns radiator coolant below a minimum level the engine will lack the required fluid to keep the engine within proper temperature range. If you experience an overheated engine it is absolutely critical that you understand the correct method to add radiator coolant to avoid causing major internal engine damage. When an engine runs for extended periods, and especially when the radiator coolant is excessively low, the metal inside the engine and combustion chamber becomes incredibly hot. Adding cold, cool or even room temperature coolant or water to the radiator when the engine is hot can cause a major internal failure. The temperature differential between the coolant and the engine will often cause a crack to form in the head, a major internal engine component. In order to add radiator coolant to a hot engine you need to ensure that the engine is running as this will drastically reduce the likelihood of damaging the engine. Should the engine not be running when you add coolant, the new colder fluid can sit stationary against internal engine components that are incredibly hot. By running the engine when you add coolant you encourage the new coolant to move swiftly through the engine mixing with any existing coolant that will be closer to the temperature of the engine itself. It is preferable to let a hot engine cool at least slightly before adding more coolant and essential that the engine is running. Adding cold or cool coolant to a hot engine that is not running will cause engine damage or failure in many cases.

3) Starting a cold engine

The majority of engine wear happens when you first start a cold engine. While the engine rests the oil inside the engine will drain to the lowest points and away from moving parts that require the oil lubricant in order to avoid damage. If you start a cold engine and immediately start driving you are causing serious engine wear each time you do this. It takes a few moments of running the engine for the oil to pressurize and be pushed to the critical areas where it is required to lubricate moving parts that rub together and cause friction. By letting the engine idle even for 30 seconds before throwing the car in drive you can drastically reduce the engine wear over the lifetime of the vehicle. In extremely cold weather a longer period of idling is required to allow the oil to become viscous again.

4) Regular oil changes

Replacing the oil every 5000 kilometres or 3000 miles is essential to maintaining a smooth running engine. Even if you tend to not maintain your car properly, this is one rule that you should absolutely adhere to. Oil changes are one of the cheapest maintenance items you can do to a car and one of the very best things that you can do to help your engine run, trouble free, for a long time. A new engine can cost thousands of dollars while an oil and oil filter change can be completed for between $25-$50 in a matter of minutes.

5) Timing belt replacement

The timing belt is a critical engine component, that should it fail, can cause major engine damage and even a total failure of the engine. The timing belt is a relatively cheap part, costing only $50 or so dollars for most cars and can be changed by a mechanic shop in as little as 30 minutes. It is recommended to replace your timing belt every 100,000 kilometres or every 60,000 miles as preventative maintenance. It is also recommended to replace the timing belt any time a car has been sitting or stored for periods of two months or more as they tend to become reliable when not in use for extended periods of time. By the time a timing belt breaks, the damage has already been done so protect your investment with this minor preventative maintenance measure.

Cold Weather Coolant Tips

Radiator coolant is vital during hot weather because it prevents your car from overheating. The coolant increases the boiling point for the water in your cooling system, while drawing heat away from vulnerable engine parts. But do you know why anti-freeze is equally as important in cold weather? Because it prevents the same water in your car's system from freezing up and destroying portions of your car. Did you know that anti-freeze is still important in the cold weather to prevent over heating, no matter how cold it gets?

In the coldest weather, anti-freeze is important to prevent the evaporation of vital fluids. Water evaporates rapidly, whereas anti-freeze does not. The lubricating properties of anti-freeze are also very important to remember. The hoses and other important parts of your vehicle need to stay protected too. Cold weather is brutal on your car and all of its moving parts, including the passengers.

This is perhaps one of the most crucial uses of anti-freeze, to keep the heat in your vehicle running. Without this precious green liquid in your car's system, you won't have any heat to stay warm when temperatures are frosty. Many people aren't aware of this fact, and they think that when their heat stops working that they have a mechanical problem of some sort. They fear radiator leaks, heater core failures, a thermostat being either stuck open or closed, and all of the other possible things that can go wrong that causes a car's heater to stop working. The truth is, what many don't know, is that being low on anti-freeze can cause your heat to stop working.

When cars are in extreme cold weather, it is sometimes necessary to start them every few hours in order to keep them from freezing up entirely, even with anti-freeze in the system. In areas of the country and the world where temperatures are well below zero for extended periods of time, engine block heaters or frequent restarting of the engine can be required in order to prevent catastrophic failure.

Starting a car in frigid temperatures can be quite punishing. Fluids that have been lying dormant in the system have to instantly be called to life and circulate quickly throughout the system. Anti-freeze is among the most important throughout this system, along with the lubricating fluids; oil, transmission, and brake. Your car has to instantly start circulating the fluid so it will keep itself cool and keep you warm. It's no surprise then, that car mechanics and car makers agree that keeping your anti-freeze at the proper levels is of paramount importance at any time of the year; especially in extreme heat and extreme cold.

Add coolant to radiator, or have thermostat checked?

I have a 97 transport that takes Dexcool. Bought it from a private seller two hours from home. Put Peak antifreeze in it without realizing it needed Dexcool compatible anitfreeze. Drove for about 2 weeks and temperature guage went up and down and there was little to no heat but car still drove fine, engine never shut off and wasnt too hot. Had a friend drain ALL the antifreeze out of the radiator and the plastic tank. Didnt know they put straight anitfreeze in it without adding water. Drove about 1 mile and the low coolant light came on and engine overheated and van shut off. Took out some of the straight antifreeze and added water to the rest but its still overheating and theres not much heat. I dont think he added coolant to the radiator, just the plastic overflow tank. What should I do?

Get ready to replace the intake gaskets.

LIMP HOME MODE... just wondering how many x-type owners, who claim to have had this problem, will admit its there fault. Check out top gear's jeremy clarkson, s-type diesel manual trying to get round the nurburgring in under ten minutes.
