My recent problems have me thinking I had better pay attention to coolant more. What do you guys use for testing and coolant additives? Looking for specific brands, sources too.

I just had a '71 4020 engine rebuilt. It was getting hard to start when the temp was cooler than 50 and it got to burning a couple of quarts of engine oil the last 2 years I planted with it. Got the sleeves out and there was very little pitting. The guy who was doing the rebuild was surprised that the o-ring grooves in the block didn't have to be rebuilt and wanted to know what I used for coolant and how often I changed it. I use deere's premixed cool-gard and changed it every 5-6 years. No other additives. I even use it in my international truck that has the 466 diesel.

You can also buy coolant filter kits and T them into your coolant system. The filter also treats the coolant.

I know another thing I learned after installing a Garn wood stove that my water is not suitable for coolant fills. The TDS is too high in my water. I will be sure to buy distilled water from now on out.

I don't test, just use new coolant with anti-cavitation conditioner every other year.

Through the local truck parts house he has test strips from Baldwin I use look much like the Donaldson ones in the other post shown. I go through everything in the fall. I only treat the wet sleeve engines. No gas or dry sleeve engines.
Pay attention to what sort of coolant is in your equipment to begin with. There are many different additive packages today. Some of these additives are compatible and some are not. Some of the incompatible ones will turn to jelly if mixed.
The test strips are specific to a certain additive chemistry. And, they have a shelf life. Deere has a couple different test strips available. Most parts stores will carry the ones for traditional "green" coolant.
I lean towards using Deere Coolgard II in most of my stuff these days. I know it is of good quality, and there is a Deere dealer every 40 miles in my neighborhood.
If you don't know what you are starting with I would recommend a complete flush and refill with a quality coolant that you know what you are working with. If there is gunk in the cooling system, Fleetgard Restore and Restore + are good chemicals to use to clean it out. Restore will remove sludge, and Restore + is for mineral build up.

We really like the Fleetguard ES Compleat (that's how they spell it) coolant on our farm. We find it to be a superior coolant. Looks like windshield washer fluid. Some of the tractors we also use have the Caterpillar heavy duty diesel coolant, a deep orange color, also works very well.

I bought my test strips at NAPA, but they were double the price for the additive over a smaller auto parts chain ($20/pt vs 10/pt). When I was getting my filters and oil at Deere, they had half gallons for around $26, so I bought a half gallon. I will have to double check, now that I hear the additives are type specific.
I never do anything to the coolant unless I add some if its low, which is hardly ever, my 2000 f250 7.3 powerstroke diesel, 208,000 miles never did anything to the coolant, my 1989 3500 Chevy 350ci 178,000 never did anything to it, 99 Dakota 172,000, my friend did intake gaskets and I don't remember if he changed the coolant. My ford 4610 tractor, 4100 hours same coolant as when it was bought in 1990.
