Happy Holidays everyone,

Temperature questions seem to focus on running hot, but my question is just
the opposite.  My '90 multivan runs cold.  I just drove home over an hour
and the temp needle never even crept up.  I did have the heat going full
and was driving highway speeds, and the air temp in MD was in the 30-40F
range  This is not uncommon for this vehicle.  If I let the car idle for a
good half hour the temp guage does rise to a little less than midway so I
assume the gauge is working.  Also around town the guage will rise
slightly.  Is there a problem that can arise from not running hot enough?
I am getting ready to leave on a long trip and wanted to make sure.

Thanks in advance,

Kevin
