Factory temp gauge? if so, try an aftermarket gauge to make sure you are getting an accurate reading. Maybe replace the temp sending unit. Does your radiator have any cool spots at operating temp?

fresh engines usually run a bit warmer than usual during the break-in period.

I personally don't trust running the fans off the thermostat, I use a toggle switch and keep them running.

i loosened the coolant temp sensor (the one for the dash gauge) and alot of air came out, then closed it when coolant started coming out. even tho i burped it anyway. [ 2013-07-22, 08:55 PM: Message edited by: dean-93 ]

I would say temp guage. Get a thermo reader from harbor freight and check it that way
Need to know the lower and upper hose temps

If you check temp of upper and lower temp. That will tell you rather thermostat is opening or waterpump not circulating

sure you don't have a blown or leaking head gasket? I had a slow leak with my supercharged 347 for a while, I would have to keep topping off my coolant (no water in the oil at this time) so I did a pressure test and found out my rad hoses were slightly loose, then a few weeks later while driving normal, the temp shot from 180 to 210 so I shut it off and checked the dipstick and sure enough-- water in the oil. pulled the heads off and found out I had a warped head. Just a thought.

That's my next guess but heads were checked before install and car only has 400 miles on this set up

Do you have a mechanical fan setup you can put on? Maybe your not pulling enough air.

Check to make sure your thermostat is opening? That's a quick easy fix and should only cost a few bucks
