| Pop quiz, what's "reverse alkalinity"? Whatever it is, mine is below 3.0. |

| It's reserve Alkalinity, not reverse. How well the coolant can handle acid contamination. |

| OK, I have been reading up on this. I guess what confused me is the new test strips I got. The old ones just said Ph. So, the 3.0 is the ph level and I need to bring it up to at least 5.0. Anyone have a recommendation on additives. I don't recall having much trouble with this over the years. We keep our buses for close to 20 years so I want to figure this out. |

I'm with you on that. I haven't had a coolant engine related issue other than the DT466 o ring, but that was an IC issue not coolant. |

it's more for 'wet sleeved' engines, the sleeves vibrate fiercely , forcing the coolant molecules to continually bounce away from the sleeve & then return with a 'violent' collision, over time the sleeve can pit and cause a hole. most every modern wet sleeve diesel engine has a coolant filter which is not an actual filter, but a cartridge containing dca's that attach to the metal parts & sleeves, protecting them from pitting.
in a tradition solid block, the dca's (additives) do squat, although some say it helps protect the waterpump in the same way. |

| This is on a propane engine. I have always ran Cat extended life coolant in all my diesels. I seldom change the coolant and have never had and issue. My oldest bus has 250k plus miles and is 18 years old. It's sitting right in front of me now. It actually looks & drives pretty darn good to be that old, if I don't say so myself. Wish I could post pics on here as easy as Facebook. I may try to post a pic here in a few. Pretty proud of it for some reason. lol |

| I also have two on daily routes. One gets mega miles on it. I have 4 that serve as spares. Never fail to start unless the batteries are down. |

Hey Bryan this is a little off your topic but since you mentioned your GM buses I am trying to find a "Low coolant" sensor for my 2003 BB B7 chassis with the 8.1L in it. It sits in the radiator on the right tank about half way down. I put a new Carquest radiator in it.My GM and parts store cant't find anything for it. Also BB dealer said no. HELP! Any ideas?

Hmm, all mine are in the plastic tank on the right side of the engine compartment. What's the sensor look like? |

I found another GM dealer that was able to locate the "switch" which I called a sensor. It has two prong hookup and is plastic. It twisted off during removal.
I will see if it is correct today when it comes in.

Bryan, The switch worked for my radiator. It is in the right hand radiator tank.
