I neglected to post the mileage when my message came up. I was under 13000 miles. It will be interesting to see what Paul comes up with on this matter. I am still unsure why the owners should bear the cost of this testing, especially at 13000 miles. If anyone is interested, I would split the cost of the kits for the testing. Even the dealer is complaining about the cost.

The "Check Coolant" message does take into account both miles drive and hours of engine operation. Basic calculation is 1 hour of idle time is equivalent to 25 miles driven. So 15,000 miles being equal to 600 hours of operation or any combination of the two before the message is displayed.
For clarification, as I previously mentioned for those that may have missed the other thread, many of these trucks are used in stationary applications for longs periods of time. Many have PTO conversions that drive all sorts of equipment, power generation, pumps, etc. so it's important to know running time. -Paul |

I am just shy of 13,000 miles/ 418 hours and i noticed the message "check coolant additive" about 100 miles ago. Does that mean it just needs to be tested then resetted?

My check Coolant message finally came on - So I went to my local dealer and they gave me a few test strips - unfortunately I don't have a chart to compare them to - Does any one know what is the appropriate color after the coolant is tested to be OK? What color will the pads be if the coolant is not OK? Also the strips that were given to me have three small pads of different colors on them - Did I get the right strips? If so - is one of the three color pads supposed to be colored more than the others if the coolant is OK? - Please advise.
Thanks |
The OAT type coolant requires different test strips than other Ford coolant types. My dealer has to order them in when my light came on. I can not answer the color questions.

The standard for industrial engines is a combination of hours and fuel used. That tells plenty about how hard the engine is worked as well as how long. Mileage is only a proxy for how hard the engine is worked.. though using it with hours can get you a proxy... I still like fuel used and hours better. |

Buy the strips from Partsguyed.com by mail order and you be sure you get the right ones and at good prices.

Anyone have these strips that can answer my questions?

I've posted the general test procedures for 6.7L coolant testing here... https://www.ford-trucks.com/forums/p...ictureid=48451
My apologies for the scale but the site forced me to rescale the image. If someone could advise how to post a .PDF here, it would make things a bit easier. These newer OAT coolants provide significant benefits vs. the traditional glycol based derivatives. Cooling performance requirements continue to scale upward with higher engine horsepower and torque ratings along with decreases in NOx & CO2 emissions compliance requirements. Heat exchanger technology for things like tube material, changes in base metals, gauge thickness, high efficient heat transfer methods and some of the more obscure influences such as the heat exchanger core solder flux that's used during the manufacturing process all have an impact on coolant life. Using the incorrect coolant type can cause nasty things to happen like gel formation. For the 6.7L, under most typical customer usage profiles (duty cycle) there's minimal risk that the coolant will breakdown prematurely. Severe operation under the most extreme conditions (max trailer weight, etc.) will over time erode some of the coolants protective properties. During our internal reviews it was deemed important enough to add to the message center as a friendly reminder to monitor coolant condition at the given mileage intervals. -Paul Disclaimer: I work at Ford, but this is my own opinion and is not the opinion of Ford Motor Company. A point of clarification. In the attached link with the coolant check process, that table calls out Rotunda test strip 328-00001, but the diesel supplement calls out Rotunda 328-00007. I'm thinking -00007 is correct, but wanted to make sure |
