I am having big problems with my Wagovan. Put in a new radiator, no help, put in a new switch for the fan, no help, put in new thermostat, no help. What happens is when you have to wait in traffic it starts to heat up, then you move along doing the speed limit, the gauge comes down, but if you have to go up a small hill it heats up again. It never gets into the red zone but darn close to it. Now I am an old lady and this is my first AT, always drove stick shift and I love it so I need all your expert advice on what to do.

 

if youve replace all of that then the next thing would be to replace your water pump.. but first check if its got sufficient flow to be sure if its your water pump to begin with.
