About Replace Coolant Pump of M276

What diameter clear tubing did you use ? 1/2 inch ?

6 mm

What size hex to loosen the drain ?

6.1 Loosen drain screw (7) on the coolant pump (8) until it can be turned by hand, 6Nm (80lb-in) +90° for installation;​

Thank you ! However, I think the drain for a W251 is different than a S212.

The WIS for drain coolant is on the end fo page "Replace Coolant Pump of M276"

At here

Hello Senior Leigh,

Excellent content that you create.

My current copy of MB Virtual PC is not working due to a problem with the VMware. Would you be able to post the WIS for draining coolant for a S212 ? Thank you. VIN WDDHH8JB5DA728493
