On my last trip we got up into some freezing temperatures so we used the dash heater. In Alburquerque I noticed a small amount of engine coolant under the left front corner of the coach. The next day we only used the AquaHot heater. We stopped in Williams, AZ and there was no coolant under the left front. We got up the next morning in freezing temperatures and there was a pretty good puddle of engine coolant under the left front of the coach. I spoke with Tommy Key at Newell who stated the dash heater core is under the dash on a metal pan that would drain any leakage to the left front corner of the coach. He stated if the heater core is leaking the dash has to be removed, core box opened and it is about a days job. He said to first try tightening the heater hoses that connect outside the core box. We didn't use the dash heater for the rest of the trip. I only got leakage on nights when it froze.

When I got home I removed the top of the dash. Could see the heater core box in the middle of the coach, but could not see where the hoses connected. I removed the cover that fits over the brake pedal. To the right I could see two heater hoses, but not where they connected to the heater core. I could also see the metal pan & it had remnants of engine coolant. I felt down by the floor to the right & felt where the hoses were clamped to the heater core. "In the blind" I tightened the lower hose a little. The top hose took no tightening. It has now been almost a week and no more leaking under the coach even in the freezing morning temps.

Hope this helps someone............................
