Temperature guage
What is your question?
The temperature guage moves to a hot temp and then back to normal repeatedly during operation. I had a radiator leak and put in stop leak. What causes this?

I have not had the thermostat changed. Ive owned the van for 8 months so Im not how old the antifreeze is. I was thinking maybe getting a flush and changing the thermostat.
