Do your gauges seem to read fairly accurately? I wouldn't expect the gauges to work as well, with the probes being out of the mainstream flow of coolant contact (not directly in the head).

 

Hmm...I never thought of that. I'll have to compare them to the data logger next time I have it hooked up. I'm sure they might be a few degrees off from each other.

 

As Cam69 suggests, sensor has to be in the flow to read coolant temp.
If not, then they read ambient temp as the fittings will dissipate heat to the atmosphere.

If one cannot remove the plug in the head, one can install a doubled nutted 4-sided nuts on a short bolt, insert into plug and use a long handle/extension - more leverage - more torque. Always worked for me.
