How are you measuring the temp? The gauges can go bad.
Possibly air in the system?
Bad intake gasket or head gasket causing any leaking? Are you losing any oil or coolant?
Is there any tan gunk under your oil cap or sludge in the coolant?
Not losing any coolant or oil maybe it could be air in the the hot coolant light came on and it started sputtering so I pulled over I did have some sludge building up in coolant flushed it before I put the new radiator in and I’m just going by what the gauges say oil still looks good had it changed about a month ago
When it overheats, are you able to hop out and open the bleeder screw? I'm curious if you are getting air into the system, and if it's this frequently, you could be having headgasket issues.
I just replaced the thermostat again and those small hoses that connect to the bypass valve and the bottom of the throttle body and refilled the system with coolant and bled the air out Is this normal operating temp for you guys ?
Id say thats a little warmer than you want but not unheard of. If its higher than usual I would suspect a problem. I wouldnt see that on my 3400 unless the temp outside was above 100...
Well I’m using dex cool 50/50 blend bled the system took her on a test drive and she drove like a champ until about a hour went by then she overheated again.... at this point idk what to do anymore
This story sounds very familiar. Chibi has a point when he asked earlier, if you can pull over and leave the car run and pop the bleed valve. If you do and air shoots out and this is a repeating cycle, my money starts leaning to head gasket. Reason, combustion gases have higher pressure and force gases/air into the cooling system through the failure in the head gasket (between a cylinder and the water jacket). It may take a while before you start to see white smoke out of the exhaust (another head gasket sign).
