10V I-5 Coolant flush procedure, if you please.

[Carl & Dawn]

Huw,

Thanks for the reply.  The needle used to hover at the halfway mark to maybe about 2/3 up MAX.  The car sat for a while and now it runs right up to the 3/4 mark and the temp light will blink if I stand still long enough.  The fan does kick on, a lot while sitting but it is still not enough.  When the fan runs constant the needle does not budge above 1/4.  I would imagine that when
on the highway you would not need the fan at all but if left off, the needle will eventually run up and the temp light will start blinking.  I pulled the radiator and it looks and flows good so that is why I am pursuing the thorough engine flush option.

Thanks a lot!
Carl
