Thoughts on coolant flush
I have religiously changed the coolant in the E300D every three years. This year marks the three years since the last time I did it. But the E300D has kind of been relegated to being a little used garage queen for the past four years or so. I've put 12,000 miles on it in three years since the last coolant service. I checked the coolant today and it is nice and clean, good to minus 30 and is giving me a reading of under 100 mv when I tested it with my multi-meter. It's got Zerex G05 and distilled water in the system now and keeps a nice steady temperature of around 165 to 170 when driving.
I was all set to do it, but after today's checks, I'm thinking it can easily go another year or more.
