Intermittent Overheating II

In the August issue there was a technical question called “Intermittent Overheating.” One of the more common reasons for this problem is a loose water pump belt – a simple solution to what often appears to be a complex problem. It happened to me last summer and a mechanic in Sundance, Wyo., found the solution when fixing another problem on my National RV Tradewinds motorhome.

Thanks for writing, Don. Often you can hear a belt squeal when it’s too loose, particularly right after startup, but not always. A lot of modern coaches have automatic belt tensioners, but these do not always work properly. So definitely check the belt’s condition and tension when chasing down a hot-running problem.

  1. Yes I would like to find information on different manufacture’s models ( used pushers ) I am not sure of construction and type of material on most models. I am looking for full time motor home, that can give me a value and quality.
