As a new owner of a PSD, I find I am learning new things everyday. Recently I learned that I need to put a coolant additive (Motorcraft part # FW-16) in the system around 15k miles. This is due to the chemicals 'wearing out' with use. A 'booster shot' for the radiator fluid.

The info I have read says that if the engine fails due to cavitation (brought about by not adding this coolant booster), it is considered owner abuse if you don't install the additive and the repair won't be covered under warranty if you are still within the limits of your warranty.

Upon reading the label on the bottle, there are so many do's and dont's that I am loathe to attempt this in my own garage. I was going to drain about a quart of fluid from the radiator and dump the 16 oz of additive in the top of the radiator. But that doesn't see like it will be an accepted procedure if there is a warranty claim.

Any input or suggestions would be appreciated.

You can do it like Ford says and add the FW-16 at 15K miles or you can test it to make sure that the level is correct. They make test strips. Just dip it in the coolant and it will tell you if you have the correct amount.

You don't want to have the additive levels too high as the stuff is abrasive to your water pump. You want it to be between 1% and 3%. 2.5% is perfect.

You can get the test strips from Ford or any diesel truck parts dealer. You can also get them on line. MUCH better price than Ford by getting the strips and additive online. One of diesel sites with a very good reputation and a good deal on both the FW-16 and test strips:

BTW, these guys have the oem fuel filters for out trucks for $13.99. Ford wants $45-60 (retail is $60) for them.

PS, Mark, from your profile I see you are an Engineer from Pasco, WA. What company do you work for? Reason I ask is that I work with a guy that's an engineer. He just transferred in from Pasco, WA.

Dave,
I really appreciate your reply. I have the dieselpage.com website bookmarked on my office PC. And there is a pic of me and my truck on the Ford owners page (near the bottom).

I think I better order a fuel filter right away!! I haven't changed the orignal yet (21k). The test strips I can probably find here locally. I am in a hurry to check out the coolant potency ASAP. This being my first new vehicle I am trying to maintain it so that it lasts as long as all my previous ones have. I want to get 20 years of service out of my F350.

I would like to discuss these and other PSD questions via phone if you are of a mind to take my call. Email your number to: [email protected] and I will give you a call today or tomorrow.

My field is civil/structural engineering. I am currently on contract with Foster Wheeler Environmental Corp. in Richland, WA (right across the river from Pasco).

BTW: I have checked your website out a couple of times and I am very impressed with your '69 drag car. Makes my little ol' '65 coupe road racer look a little pale.

You can find the answer to this question and thousands of others at my favorite Ford diesel site, naturally, Ford_Diesel.com. Go there and look around. It is only about ford diesels and what they do, nothing else. Enjoy. Bill
