Could i remove the freeze plug in my block by tilting them (knock on the side so they turn sideways), its a GC 1993 4.0L or is they resting on som flange?

If i remove the freeze plug on the head, do i then get access to the area arround the temperatur sender? Need to see if there is some residue after some radiator sealer in there.

 

yes knock side way pull out with channel locks getting in different story...

 

thanx

 

Removing the freeze plugs will not give you access to the temp sending unit. Why not just remove the sender?

 

The hole where the sender is isnt so big that i can see if there is something there, the sender is out and the head is clean and i have flushed the water jacket and it seems to be okey. The problem is that the temperatur gauge is reading to high, i have cheked everything else and everything is 100% fine. Since the temperatur on the water is normal in front but not in the back i would see if there is something that prevent waterflow back in the head.

Radiator: new

Waterpump: new

Thermostate: new (same readings without thermostate), testet to open at correct temperatur

Temperatur sender: new (the one in the back), testet 100% correct in water up to 100 celsius

Temperatur gauge: testet 100% correct with resistors insted of the sender

Fan clutch: new

Flushed the system: yes, 3 times

Head gasket was 100% fine


Everything that is new i have replaced to correct this problem.
