Re: Change antifreeze
I have not created one on the Lambdas yet-- as im not at the 5yr or 150,000 mile range. (Dexcool is now rated at 150K)
But If I was to do it today- with say 100,000 miles--- and knowing the system has no leaks
I would look into draining the system via the lower radiator hose.
I would not even bother flushing the system.
But with most coolant drained- and 100K--- I would probably even consider changing the thermostat.
I have not looked to see if theres a drain valve on the radiator on these vehicles.
