Hello brothers. While repairing an A/C issue earlier I had the occasion to stand on the three point arms and remove the rear roof hatch to inspect the heating radiator. I noticed a slight leak on the rubber coolant lines around the heater regulator. Nothing serious, just enough to have a bit of sweat on the hoses, but not so much to actually drip downward. I am not sure I can rationalize replacing parts because of the small amount of the leak, but I was thinking of adding some tablets / pellets into the coolant to seal the leak. You know the classic leak sealant stuff. Is this OK to use in the 5625 or am I going to gum things up?
