Engine coolant maintenance is just as important as an oil change. In fact, the coolant condition in a diesel engine may even be more important than in a gasoline engine. … Today’s antifreeze-coolant not only protects from freezing in the winter months, but also helps protect diesel engines from common cavitation issues.
Do diesel engines take special coolant?
The difference between the antifreeze used in a diesel engine and that used in a conventional gas engine is that diesel antifreeze contains a special additive that protects against erosion on cylinder walls.
What kind of coolant do you put in a diesel?
Best Diesel Option: Zerex G-05 Antifreeze/Coolant
ZEREX G-05 contains a nitrite based additive that is designed to protect your diesel engine’s cylinder liners from cavitation erosion – a common type of erosion in diesel engines.
Does it matter what engine coolant you use?
Coolant in its base form is Ethylene Glycol. Now most people will be surprised to hear that coolant plays almost no role in the actual cooling of your engine. Engine cooling is done by the 50/50 mixture of distilled water in the radiator. … Well, you use the coolant that is specified in your owner’s manual.
How long can you run a diesel engine without coolant?
A bored block I would not worry so much about. At 20F I wouldn’t run it more than about 60 seconds at idle without coolant. Put your hand on the exhaust manifold on any engine after you start it, and see how quick it gets hot.
What is the preferred pH level of coolant in a diesel engine?
A very high pH value is also bad news as you risk damage to your gaskets and to the softer metal components. Therefore, the pH value in an ideal cooling system always needs to be between 8 and 10. To achieve this, you need buffers in your cooling fluid to neutralise the formation of acids or alkalis.
What happens if you use the wrong color antifreeze?
Mixing different engine coolants or using the wrong coolant can impair the performance of the special additive packages; this can result in increased corrosion to the radiator. … Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket.
Can I add water to my diesel coolant?
You can run straight distilled water with no ill effect, as long as it isn’t going to freeze. … Water actually cools better than antifreeze. You will have to run an additive in your cooling system for pump lubrication and anti-scale.
What happens if you don’t put antifreeze in your car?
Without antifreeze in you car you are running an all-vapor system! Waste heat cannot leave the engine. … Modern cars can detect this overheating with a temperature sensor and put the car into a “limp home mode” that limits engine speed but it’s a race against time before major damage is done.
Can I mix pink and blue coolant?
Most of us are familiar with two kinds of antifreeze. There is green antifreeze and orange antifreeze. … These days you can actually get yellow antifreeze, blue antifreeze, pink antifreeze and more. The fact is, mixing these liquids is not safe.
Is antifreeze and coolant the same?
Well, antifreeze and engine coolant are similar, but not the same. Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.
Is it OK to drive with low coolant?
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. If this heat isn’t dissipated, it can lead to serious engine damage. … It is not advisable to drive or run your car with low coolant because it can lead to damage to your engine.
How fast will a car overheat without coolant?
Not very long. Even driving gently you should expect things to start getting too hot within just a few minutes – probably less than 5 minutes if it’s completely dry. If your car has an aluminum head, like many do, then you should expect the head to warp almost immediately upon overheating.
How far can you drive without radiator fluid?
You should be able to take a vehicle at least 5, maybe 10, miles by following this advice. I should say that I live in an area that never freezes, so… A much cheaper option then towing, but which will ensure that nothing gets damaged, is for you just to fix the leak temporarily on the spot with some putty.
