Today I went ahead and flushed out my radiator on the '91 300E. I could not believe how much crud and sediment came out into the drain tubs. It literally looked like a sewage dump! The good news is that it did not take very long at all to get the clear water flowing out of the radiator drain plug or the engine block. I also disconnected the hoses from the expansion tank, removed it, and cleaned it all out with a hose sprayer and wiped clean with a few paper towels stuffed in and twisted around.
After adding the new coolant and running with the heater on, my engine temp was struggling to climb above 80c where it would usually quickly get up to 85c+ very quickly when at stop without the heater running! So, I guess the flushing and cleaning helped the coolant circulate better and become more effective. Any thoughts out there on my results?
I also changed out my differential oil which was black. I'm sure she appreciated that as well
