Infiniti G35 overheats but it's not the radiator
2004 G35 coupe 3.5ltr. 72000 miles, Automatic.
My G35 recently started cutting off on me while driving. I pop the hood and the radiator
is fine, the coolant isn't boiling, no apparent leaks, fans still work.
When it shuts down, it won't start again until it sits and cools for about 15 to 20
minutes. Turning the key to battery power the fans can be heard spinning very rapidly.
Turning the key to ignition the car cranks but doesn't ignite.
The temperature gauge does not rise above half, however the dash display that shows
the outside temperature says 108f - 111f, when really it is about 80 something degrees
outside.
Also, if it does not over heat and shut off on me on the road, when i stop to my
destination and leave the car for a few minutes, come back and try to start it, same
problem. I would have to wait until it cools.
Oil is at proper level
Why is this happening?
