So, in my un-officially sanctioned opinion, 3 to five years with modern coolant is just fine. In the early 2000's the factory went from a 2 or 3 year interval (I forget exactly what it was) to a 15 year interval without anything having changed but the coolant formulation. Ont thing I may have missed, Is the system truly contaminated with rust and /or oil, or are you simply wanting to do this as maintenance? If your system is clean there is no reason to do anything other than change the coolant every few years or so, and even that is somewhat debatable. I have seen radiators with both metal and plastic tanks leak at the seams after a cleaning. Since you can't put cool water in a warm block, you end up waiting hours in between to let the engine cool.īased on my personal experience, gsxr and DerFuror both nailed it. And, the FSM says to use a forced-open t-stat, which is not something everyone has sitting in their toolbox. The factory citric acid cleaner is another option, but the OE powder is very expensive, and you must flush with clean water afterwards, flush, flush again, and then flush some more. IMO, 10-20 minutes of idling won't clean much on a seriously corroded system. I prefer the type that says to use it for several hours of engine running time (i.e., Prestone Super Radiator Cleaner), instead of the quick-acting stuff (i.e., Prestone Super Flush). I've found this usually doesn't fix cooling problems, so make sure you really need to use the flush. The important thing is to flush repeatedly after using the cleaner, ideally re-filling the whole system, letting the engine get up to temp, running the heater on max, then draining it all, and repeating that once or twice. Make sure to check your engine when it is cold for an accurate reading.Leaks should not be an issue. Engine coolant circulates through your engine to keep it cool in the summer but won’t freeze in the winter. When to add coolant to Ford F-350 Super Duty?Īdding engine coolant (also known as antifreeze) to your 2014 Ford F-350 Super Duty is pretty easy. If you fail to monitor and maintain SCA’s cavitation can occur, resulting in extreme damage to the block.

The coolants that came in 7.3L Powerstroke diesels (green and gold) require the use and monitoring of SCA’s. This is the method I used to flush my coolant and convert from conventional green coolant to ELC red coolant. Now is the time to check all of the radiator hoses. Tighten the drain valve on the bottom of the radiator. Remove the radiator cap on the driver’s side of the engine bay.

How to flush the radiator on a Ford F-250?įord F-250: How to Flush Radiator 1 Drain old coolant. Add enough to fill to the “Full” line on the degass bottle. Now that the straight water flush is done and drained from the system, you’ll want to add your 50/50 mixture of distilled water and Motorcraft Gold coolant to your F-150. Your cooling system holds approximately 8 gallons. Therefore, adding pre-mixed 50/50 will further dilute the solution and yield a weak freeze point, along with a low level of corrosion and cavitation inhibitors. How much water is left in the coolant system after flushing?Īfter flushing, residual water will remain in your engine and cooling system that you can’t get out. Start the truck up to get it to operating temperature. If you wish to use a chemical cleaner along with the distilled water, mix it with water while re-filling the radiator. Once the coolant is drained and you have closed the valve, refill the coolant system with distilled water. What should I use to Flush my Ford F-150 radiator?

This is the method I used to flush my coolant and convert from conventional green coolant to ELC red coolant. 1) With the engine cold, remove the radiator cap and open the radiator drain plug and drain the radiator until it is dry then close the radiator drain plug.
