Hey guys
I have a 2004 LS sport (3.9) that Ive owned for a couple of years now. She's been very reliable until now.
The other day the LS over heated. The needle went into the red while my wife was driving it. So i trouble shoot and everything leads to the thermostat. I bought a new thermostat and housing, installed it today. The old thermostat had come apart and was pushing the housing out while trying to unbolt it. It doesnt over heat now but my diagnostic tool says the coolant temp is sitting at between 220 - 240 degrees depending if the heat or the AC is on, during idle.
So I keep trying to bleed it, but I can't get a steady stream from the bleeder at idle. When i rev it coolant will come out, but then stops once at idle again.
The system appears to be pressurized. I loosened the degas cap and pressure and heat came out... All of the plastic components and hoses are within 3 years old, minus the upper radiator hose which i replaced in 2013. None look damaged at all, still looking new.
How should I trouble shoot the issue of not being able to get a steady stream of coolant from the bleeder valve, at idle?
TIA
