Weve got a 1968 (Serial number 2601xtd) xt190 also 1969 180 gas (Serial number 7873). Wondering if there are test kits for the PH level in the coolant. I have read and heard horror stories to cylinders due to cavatition from improper PH levels.
Thanks Mack for the description on the dampner plate on our F2. Is it normal for that plate to make a ratteling noise when idling? Or, should I check for broken springs? Thanks.

| Do you know what the proper ph would be? Too much acid and you get pitting. Too much alkaline and you get scaling. I would just change the anti freeze every two years using a long life anti freeze and leave it at that. |

Yea, I wouldn't get too crazy worring about it.
I use distilled water {No Minerals that form deposits} and I add a bottle of NAPA Radiator Anti-Rust with fresh anti-freeze and run it. Regular PH paper from a drug store will work. ------------- I Love Meatballs and Dumplings on Toast with Gravy and Rosemary and ??? {Open For Suggestions} |

If you want to get really into it you can add a treated water filter and plumb it into your system. ------------- I Love Meatballs and Dumplings on Toast with Gravy and Rosemary and ??? {Open For Suggestions} |

Diesels can benefit from an additive to cut back on cavitation to save sleeves, some demand it, like Cummins and Ford diesels in recent times. Gerald J. |

| There is a science to anti freeze. I can't say I'm knowledgeable in this regard, but I do have considerable experience in boiler treatments. Water behaves the same in either case. We usually ran the water a bit on the acidic side to prevent scaling. We would also use a silica formula to coat the metals to prevent pitting. Think of anti freeze as something that does more than just preventing water freeze. It acts as a lubricant for your water pump bushing. It prevents corrosion. It prevents pitting. I like the 50/50 pre-blended anti freezes as they already use distilled water. A high quality anti freeze should come as a complete chemical package. That should be all you need. Just change it before the additives "wear out." |

| My dad became interested in checking the quality of our antifreeze last year. Wix sells a kit with test strips that check the ph. Wix also sells a additive to boost older antifreeze. It wasnt very expensive and it atleast took my dads mind off of it!!! Is it really important or not?? Ryan |

We get test strips from the BG folks. For Powerstrokes, the specs they give us is above 800, the coolant is good and requires no attention. 300 to 800 the corrosion additives are weak, add a rejuvinator and retest. Below 300 must flush. I'd say if there is any question about your coolant, change it. If you have a 6.0/6.4 Powerstroke, change it! ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

| We can really open a can of worms and discuss motor oil, Ryan. Suffice to say I believe in buying a quality product and not trying to stretch it beyond its design life. For what anti freeze costs, I just put in the good stuff and change it every couple years. I also use extended life motor oil in my car and change it every year. At first I was very hesitant to do the extended change intervals until I had the oil tested at six month intervals for the first couple of years. The oil was tested in a very scientific way. If I were to have my anti freeze tested, I would want it tested in a way that is more thorough than a piece of paper that only tells me the ph. |

The dampner will raddle but the more they wear, the more they will rattle.
Antifreeze, put a coolent filter on and change every year and change antifreeze every 2 years. You would not beleve how clean the water area of the block is when a operator changes the filter every year. MACK

I got a test kit at NAPA.

Flush it, Fill it and run it.
It lasted this long if you get what I mean. You can study acid, corrosion and anti-freeze properties the reast of your life and you still will get some corrosion. ------------- I Love Meatballs and Dumplings on Toast with Gravy and Rosemary and ??? {Open For Suggestions} |

| I had this conversation several years ago when I had my 185 overhauled. Someone said to use tractor supply fleetguard anti freeze that it would help stop cavitation. Keep the tractor long enough and you will probably still have problem no matter what you do. Bill |

Friend gave me a bottle of CAT additive. I drain it and refresh it every spring and add the recommended amount to the mix.

Thanks guys for all the input. Doug S that is a very informative link, Thank You. Dad has owned the 190 for 20+ years it replaced a D19, and the 180 for only 4 years, the 180 replaced a D15. Somewhat know the history of the 190 (bought local from a dealer) but the 180 has been rode hard and put away wet. They only run 30-35 hrs/yr so I didnt know if that had any effect on the coolant condition. |

The 2900 engines were bad about eating up the liners. I've overhauled 3 myself that had the liners pitted to the point of leaking. I like the water filters myself. We run them on our Cummins engines (that are also know for eating the liners) at work with good results. |

I just put Fleetguard antifreeze in my 931 Case, but if I had it to do again i would use an extended life antifreeze that meets Cats EC-1 spec. A little more expensive, but you never have to worry about additives for longer than most of us own tractors! 600k miles, 6k hours or 6 years, which ever comes first. http://www.finning.ca/_downloads/sos/Extended%20Life%20Coolant%20Data%20Sheet_pehp4036.pdf |

I would still change the antifreeze every two years, Rawleigh. Unless you know the engine is pristine when you first start using an extended life antifreeze.
Others: Tell me more about the water filters. Who makes them? What's the easiest way to install one on a D2800?

Many make them.
Fleetguard is a popular one. You will have to find a housing for it that you can plumb into your system. ------------- I Love Meatballs and Dumplings on Toast with Gravy and Rosemary and ??? {Open For Suggestions} |
