The temperture gauge on my 95 Villager is going all the way up to the hottest point. Sometimes it's ok, and sometimes it goes up and then there is no heat in the van when that happens. There are no leaks and the radiator is full. Eight months ago when this happened I changed the thermostat (A miserable job that was made worse by the fact that the haynes manual showed the thermostat going in upside down, so I had to do the job twice.) Is there any thing else it could be since the stat was changed less than a year ago although I do have the same symtoms. Thanks in advance.
