2001 230 VS, I was using my heater this weekend and noticed my water temp rise, as soon as i turned my heater blower off the temp went back down. is this normal?

That is weird. Using the heater should have the opposite effect, I would think. How much did it change the temperature?

Hey guys still have temp issues when i turn on my cockpit heater. Temp runs at 170 without heater, when I turn blower on its runs 30-40 degrees warmer, as soon as I turn blower off it returns to 170. Any ideas?

Any ideas?What if you have the heater valve open, but leave the blower off? If it is only when the blower is on, I would bet it is a wiring problem. How fast does it go to 200-210?

I am with Table Rocker. It has to be some kind of electrical problem where turning on the blower switch is doing something wacky to your temp gauge. If your heater is like mine, water is flowing through the heater all the time, whether the switch is on/off. The switch simply turns on the blower fan.

The temp goes up pretty much instantly maybe 4-5 seconds.then goes back down just as fast when I turn it the heater off.

You can rest assured it is electrical and not the actual temp going up.

Agreed...no way that the engine would change temps that quickly. Sounds like a grounding issue, or insufficient current to one of the associated devices on that breaker.
