Each manufacturer is specific to change intervals. GM recommends 5 years or 160k on the newer models. However it has been noted that their Dexron coolant is not able to last that long. A safe interval is 2 years or 60,000km whichever comes first.
could you tell me how often should coolant be added to my 1998 el.ford futura thanks
This is often caused by air being trapped in the cooling system. Get a qualified mechanic to drain, flush and refill the radiator/cooling system.
flush and change cooling system liquid every 2 years. use correct liquids for your vehicle.
It is not necessary to flush the power steering system in a car. However, you should check the power steering fluid level in the car each month.
never unless there is a leak in the cooling system
A water heater flush should be performed once a year to maintain optimal performance and efficiency.
It is a good practice to flush the engine after each use, particularly if operated in salt, or brackish water. Also, if operated in shallow water where the engine may be picking up silt or sand, as any of the above mentioned may cause obstructed cooling water flow.
A hot water heater flush should be performed annually to maintain optimal performance and efficiency.
Should really flush your system every year to prevent any rusting or fouling, but at the very least every 2 years.
Although it doesn't specify how often you can use it, since it is flushing out your system and takes a lot of motivation to go through with, I wouldn't suggest doing it very often. After the flush, it is recommended to start a healthy diet to keep some of the weight from coming back on.
Water lines should be flushed regularly to maintain optimal water quality and system efficiency. It is recommended to flush water lines at least once a year to remove any buildup of sediment, minerals, or bacteria that can affect water quality and system performance.
Every 3000 miles or every 3 months, whichever comes first.
