Weird Cooling issue Hey all,
New to the forums posting but long time follower. I just encountered a weird issue I can not seem to ID. my LS3 gets to temp then idles fine. Then it goes from 190 to 230 and then back down to 200 or so. I thought it was just a thermostat... I just changed it... Same issue...
It never hits 230 for long. It goes right back down like the the thermostat opened..... When cruising on the highway it sits at 200 even on a cool night when normally with the 180 degree stat it sits at no more than 190.
The coolant does boil over when the car is parked and keyed off but when running it does not. Just goes up and down between 200 and 230 rapidly ... every 3 - 5 minutes it cycles that way.
Any ideas? Bad replacement thermostat or waterpump? The pump is not leaking and like I said it still looks to be pumping.

Check the cooling fan turn on temperature. Most likely too high. My Vette did the same thing until I had the fan on temperature lowered to 195 with a 190 stat.

It was either a 5 or 6 core cooler, all aluminium.
The top brand in the country called Adrad. Designed to cool around 2000hp.
Luckily though, they were very quick to make me another one and I had it one week later so I can't complain really..
It's currently being fitted along with my other parts.
Your issue is a tricky one..

I was pretty pissed about it as I paid 1000 USD.
