Coolant Loss - word to the wise

[Scott & Heather]

Thread revival, but don't make me start a new one. Cliff, Zerex? Where can I get this stuff? I'm low on coolant and need to top off...

[luvrbus]

Napa has it or can get it overnight fwiw Valvoline and Zerex are 1 in the same 

good luck

[Scott & Heather]

Perfect. Thanks!

   Naah, necroposting! 

haha. nice! 

Ok, so, had a short but great conversation with Sean this morning about Zerek, Shell Rotella ELC, etc. Our bus came with the green juice. So for now I'll stick with Zerex. Cliff, do I need to add another chemical to that?? Does it eat away at metal bits? Should I someday flush the system to the ELC?

Some water filters are also pre-charged (if equipped). Not entirely a bad idea if your unit is prone to sitting for an extended length of time.

Don't add anything for a while buy some test strips and check it about every 3 months I always ran a SCA filter on my bus never had to add anything the Pre charge antifreeze uses a plain filter no chemicals.

Run the green forever it won't hurt the 92 series not enough contact with water on the liner to make any difference just don't buy the WalMart green the old 2 strokes were around 50 years before the designer color antifreeze and distilled water If you want a SCA filter I have a extra I can ship to for free you pay the shipping

good luck

 Matt it's a Napa 4070 or Wix 24070 those are sold by the years and the mileage for the chemicals to last fwiw so the one you remove may be a different number but don't sweat it the above numbers are good for 2+ years

good luck

This is what I ended up buying. A call into valvoline confirmed it has SCA's in it and it mixes with green just fine. Hope this was ok.

Any word from anyone? The jugs are sitting waiting to be poured into my cooling system but I just wanted one word of encouragement before I actually did it. Valvoline says it's ok, cliff?

Color really doesn't matter. Coolant is classified into two different catagories. One is the normal coolant (like the regular green stuff) that you have to check acidity with strips and add treatment as needed. Then there is extended life. You basically do nothing to this. If you add treatment to extended life, you just wasted all your money on that extended life coolant since the treatment cancels out the extended chemicals.
If you have a wet cylinder liner engine, like a 92 series or Series 60 and most other engines, the extended life is what I'd use. With the 71 series the regular coolant, with checking for acidity level is sufficient. Good Luck, TomC
