Welcome! Looks like we'll be headed to your state soon to open an affiliate in San Antonio. Texas rocks!We just extend that breather tube down and get rid of the bottle, keeps the mess out of the radiator.
Most of the tanks we pull are for the most part clean but weve seen a few that have a real dark green sludge in them. On older models say 94-99 the steel components inside the module can be quite rusted.
