Wow... that really is a stumper.
If you are getting air lock, after a very very short time the engine would get hot as hell as circulation stops while the pump cavitates if in fact the pump is actually cavitating. But you can get air lock in parts of the system even while the pump is pumping away too.
Sounds like you need to know two things. What the actual water temp is in the engine at the sensor when you go into the red, and at the same time if water is flowing at the sensor. The only way I can see doing it, is yanking the sensor outand see if coolant comes out. But if it is air locked at the time, you will have just relieved the air lock by doing that and coolant will probably fly out..... A catch 22.
Does it ever come back out of the red while you are riding it?
I am still betting on faulty sensor system. Or least I am hoping that is all it is....
So am I Bubba, But all of the sensor system has been checked and re checked. Hopefully in the next week or so I can get it checked with the Infrared Thermometer to see what the overall picture is.
Everyone who has looked at it now is of the opinion that the engine and cooling system is fine it is just something in the sensor area that goes haywire, after a period of operation.
The temp holds perfectly until about 25 miles. then it starts to climb. Then the revs and distance and ambient temp dictate where above the gauge will sit. Once at that level whether near the red line or around the 5th line It will not come down until I have stopped for a while or get into a slower area where the revs get back down to the 2000 area.
Is there anything in the sensor wiring that could have been moved into a hot area giving false readings?
Doe anyone know if the ECU receives the reading from the sensor first then shoots it off to the gauge?
