Replaced both idler pulleys 141800 mi 5/14/2018
Belt tensioner and Belt 141102 mi. 4/25/2018

First I replaced just the tensioner pulley as it wobbled badly and a shreading belt, I noticed the belt not tracking straight, starting to lose a rib a couple of weeks later and so the whole tensioner and another new belt under warranty, one idler had slop, ordered the idlers to be safe.

mgill85258 I've had 6 total MB's now, all at least 15 years old or more, and I've also only replaced one water pump ever. It was on a 1995 C220.

Water pumps can outlast the car, so you never know.
The best preemptive repair is get a new car.

For me the water pump is now a maintenace item. If you have a second car to drive, someone to come and get you when you break down, and live near a dealer, dont travel far from home, etc them ok maybe not, but

One very cold and snowy Friday evening and several hundred miles from home, my low coolant warning came on, had to stop at three different connivence stores before i could get even a gallon of distilled water. Found a dealer, 50 miles away, just before closing, they didnt have a pump in stock, werent sure when it would come in because it was during Christmas/New Year holidays and they were backlogged a week so next Friday. So only bought coolant from the dealer. I ordered a pump from FCP while sitting at the dealers. Went to A grocery that was closed but I snuck in through the out door, a self checkout register was lit, so I managed to buy 5 gallons of distilled, by the time I got home at midnight I had used 4.5 gallons. I got the pump Monday dec 31, and put it on, wasn’t too diificult, had to pull the fan. And make sure there is no grime and grit under the high pressure fuel pump. This is why its a maintenance item for me from now on.

On my 2006 e320 cdi, the cluster temp gauge is definatly not a dummy, when the thermostat went out in the dead of winter, my gauge would only get up about about 40 degrees during a long idle, once the car was underway the gauge would drop to 10 or lower.

Kajtek1 Just becouse you don't see junk on top of the radiator, doesn't mean it is not packed at the bottom.
Anyway, I always appreciate when somebody volunteer to be Guinea Pig.
Still even with your positive review, I am not taking my chances for $5 saving.
We are long way from times when radiators cost $120.

Why not? What exactly is wrong with it? Is the Mercedes cooling system made out of some material that isn't found in any other car? Please explain.

Before I start driving MB, I had to replace radiators on 3 vehicles only becouse of build up the green coolant developed after few years.
Still remember $120 for Volvo radiator with lifetime guarantee 20 years ago.
Sweet times.
That's odd. My 2 Volvo and 3 Mercedes use the same generic green coolant and never encountered any build up. Here's the inside 16mm radiator I just pulled from the E320. I don't see any green build up. Do you?
