Try putting a colder thermostat in- I have heard of people testing thermostats and then find out it was bad so try a 180 degree-Denny
SOURCE: over heating mitsubishi k4n engine
use 50-50 antifreeze and change your radiator cap but first drain all the old antifreeze out.. hope this help
SOURCE: I have a Nissan Patrol Y60 TD42. It overheats
sounds like something clogged in the block its self try to find an acid flush and flush the system a few times untill it comes out clean
SOURCE: 1996 dodge ram. Vehicle runs hot. I have replaced
Hello there"
sounds like you have done a lot with this there is a few things that you can do to ensue every thing is running right.
first if you can get a handheld thermal gun and check the temperature at the temp sensor on the radiator or block then see what it reads compared to the guage to ensure the guage is correct.
next check the temperature at both the top and the bottom of the radiatoer if there is a big difference in temps the radiator is partially blocked a radiator will increase 30 to 100 degrees if the radiator is 20 percent blocked.. also check to ensure that the radiator hoses are not collapsing.
Now ensure that you are not gettin air in the system by way of the water pump gasket or by loose hoses ok?
and finaly check to ensure that the heater core is not leaking and drawing air into the system or is clogged this will make a vehical give the overheating symptom also ok?
Let me know how this is going
Best regards mikle

Since you have no circulation with the thermostat on-is it a new thermostat?- if yes,even though do not trust the thermostat, test him by putting him in a boiling water and with a thermometer,follow whether it operates on the temperature specified. Most probably does not respond.
