Drain vs Flush coolant
I've read a few entries on this and have been doing my homework, but thought I'd post the question to the forum for your feedback.
I have a '00 Durango, 4.7 V8 4WD. It's just shy of 123,000 miles. I bought it almost 4 years ago so don't know the service schedule on it, although I either take it in or DYI on most regular service needs.
Q: Is it better to drain and refill the coolant or have the system flushed? I beleive the coolant in the system is the original and it's started to become dirty over the past few months. To my knowledge, the system has never been flushed, nor has the coolant been changed.
I know some pros and cons to both, but looking for any advice on what the group thinks.
