When changing the coolant is it worth the time to do the following:
-- Disconnect the coolant hose on one side of the oil cooler. The hoses to the cooler go up on both sides of the cooler. So, the coolant doesn't drain completely from the cooler and a portion of the hoses. It would seem to be very easy to disconnect one of the hoses at the cooler to get a complete drain.
-- Disconnect the coolant hose to the cold idle actuator assembly beneath the throttle bodies. Using compressed air push the coolant through the assembly to the radiator. Disconnect the hose where it connects to the thermostat assembly above the engine head.
These are two areas where coolant might not totally drain from the engine/radiator.
All of these areas would be easily accessible when I check/adjust the engine valve clearances and drain a portion of the coolant. Seems like an opportune time to change the coolant.
