Changed coolant in '94 102DL. Radiator sight glass is stained green from old coolant and new Texaco red doesn't show without climing up to get whithin a few inches to be able to see the level. I tried to wrench it out, but it seamed to want to stay put. Does anyone know if it screws out or is it normally soldered in? Now I'm hopping the new red will eventually desolve the old green stain. Thanks for any and all help! Skip |

If there is a large hex head around the sight glass then it screws out. Put a large socket wrench on it and have at it. Thanks, DrEd. |

I sure wouldn't want to be wrenching on that,sounds like an expensive mistake. whoever took care of my bus before me made a 'checker' out of a piece of coathanger,just long enough to reach into the neck & come out with one inch of 'wet' on it. it's an old coat hanger,with the paint sanded off & it has a very lite coat of rust on it,just enough to show 'wet' easily |

For what it's worth, Skip. A friend of mine has a fleet of trucks, running CAT C14's, and he was running red coolant in some of then. He lost 3 motors from cavitation. Went back to green and no more problems. |

Don't see how red coolant would cause cavitation.
Cavitation is normally caused by a mechanical force ( water pump impeller, prop etc) Correct?
CAT Coolant is Red, and Have used it in my 4104 for more than 10 years. |

I would be more inclined to say the person that put the red in, left a big air bubble in the cooling system,color does not do things like that |

Ron,
Are you talking about cavitation or aeration?
I'd "lean" towards the following distinctions.
Coolant that has less capacity to raise the boiling point of the mixture would exhibit increased aeration.
Coolant that, for example, omitted or reduced a surfectant would be more prone to display cavitation. |
