Hey,

The wife was driving home from work and got the "coolant top off" alert. I checked it and it was low but not much about 1/2 qt so added the blue stuff. I did take a dropper and pulled some out to see the color and notice it was very clear and not as blue in color and dirty so planning to flush it.

My question,

Where is the engine block drain for the ML350 from the VIN I get this specs?

Engine 272967
Transmission 722906

I see some folks mention that if you pull the lower coolant hose it drains from the block not too sure on this statement?

Cheers,

Pulling the lower hose only drains the radiator and partially drains the eng.

The block drains are directly behind the motor mounts.
Thanks for the information I did the drain but not from the crankcase it is impossible to reach.

On another note I am having an issue with my cooling fan it is running at high RPM sounds like a jet engine fan. I did the scan and it gave be coolant temperature senor 1 fail error, but there is no CEL and the instrument dash gives a proper temperature.

Any thoughts

The Coolant Temp Sensor is located on the rear of the eng.

Tonight I tried to trouble shoot it more came home from work to find out that the battery is getting weak so had to jump it. The code for the coolant temp. Sensor remains. I had to disconnect the radiator cable because looks like its draining my battery. Going to have to take it to my Indy to get the ECM corrected since my scanner can’t do it.

What radiator cable?????????????????

You must own your own scanner.

Sorry I meant the radiator fan power cable for the radiator fan so that it's not engaging and turning on. I disconnected it last night so that my battery does not get drained. What I noticed was that since the fan was spinning on high at idle it was draining my battery.

Here is the scanner that I have. Foxwell Scanner NT510

That scanner should do it without a problem. I think you have faulty ECT sensor. That's why code will not clear.

Update.

I took it to my indy and he was able to clear the code and the issue is gone. I am not sure why my Foxwell scanner didn't clear the code but, everything is fine now.

Thanks for the help.
