It appears that the Shell Rotella line has recently undergone a reformulation. The plain old, Rotella T (if I'm reading correctly) is going to go away. We are also now on the "CK" cert, up from CI and CJ4. I've always been leery of any kind of additive for anything (fuel, oil, coolant). The...

The "three types" were covered in Frank's articles. Ok, I get that our trucks need ZDDP in the oil but which of the 3 classes? Also, the articles indicate that not all additives play nice with all types of oil. So which additive/oil combination is safest with our engines and will protect them...

Whoops, I missed this post last night. Very interesting (and reassuring)! Yeah, no problems with removing the radiator. I have to replace all belts and hoses on the truck so I suspect that it'll just be easier with the radiator out of the way. I wanted to do this stuff this winter because I...

Thanks for the solid answers, guys. I've been driving clean, new cars for too long.

That was always the plan. I was just testing the coolant Ph to see if it was acidic while the truck was sitting and what kind of trouble the cylinder liners might be in.

Great, thanks gents.

Following advice given here, I performed a coolant test today, using test strips. The kit says it measures freeze point, nitrites and Ph. I opened the drain cock at the bottom of the radiator and a pure black fluid resembling engine oil drained out. After swearing a few choice words, I calmed...

My M813 is missing both wiper arms (and the nut that holds the arms on). I have the original pneumatic wiper motors and they work fine. In the archives, the NAPA part number is obsolete and not available. Anco wiper arms P/N 41-01 is listed as a possible replacement. Has anyone successfully...

I haven't read all of the articles, but it's very interesting reading. Frank, what is your background? Chemistry? Based on all of these articles, what is your oil of preference for old military vehicles with unknown maintenance histories?

According to an article that I read yesterday, 2018 autumn was the wettest on record for the U.S. Maryland is forecast to get almost 2 inches of rain this weekend, which will bring us to our wettest year ever, since records started being kept in 1870. We're something like 2 feet over average...

NICE. I'll bet the neighborhood kids love the "drivers."

Thanks, Scar! I am a bit concerned that the engine sat "pickled" in sour coolant over the last 8 years while it was parked. Test strips and a coolant flush are #1 on the list.

Regarding my previous question: "Where exactly is the air purge valve (petcock) for the fuel system on the M809 series trucks?" Several trips through the search engine mention the valve but I could find no photos and no specific description of its location, only instructions to "open it" when...

Ack! Don't mix brake fluids. As to your earlier question, my reading (and brief experience with my own truck) indicates that you should be hearing air when you shift between reverse and 1st. The reason for this, is because it operates the "sprag" in the transfer case. These trucks are always...

Looks very clean. Congrats!

I hear you! Amazingly, the brakes are firm and no leaks detected but due to the age, I'll have to work my way through them. The A1 has the drop-down sides, lucky guy.

While I'm waiting for parts and generally trying to get through Christmas...

God, I hope you're right. Ok gang, first question- Using the Operator's TM for the M809, I drained some fuel/water/sediment out of the fuel/water separator. (Pg. 3-15, item E, service fuel/water separator.) Page 3-16 describes opening the air purge drain cock in the engine compartment to...

Well stick around. I need people to tell me "You're doing it wrong" while I try to get it road worthy.

Whew, read this thread from start to finish. Incredible job!
