| G-AMG G-Class DIY Host Date registered: May 2006 Location: South Texas Vehicle(s): '04 G55, '80 280GE, '99 S420, '98 E320, 2011 E350  | Photo DIY- Thermostat R/R M112 Well, I have been noticing a slight issue... made apparent by our relatively "Cool" Winter, this year. My Coolant Temperature Rise has been on the "Slow" side, and sometimes barely making it to 80C during a 7 Mile Commute. To make matters worse, I have seen (with my Own Eyes this time!) the Cappuccino/Mayonaise goop under the Oil Cap. This confirms my presumptive diagnosis of a "Lazy" Thermostat. Not out-right FAILED... but rather "Leaking" or Not Fully Closed. For those folks with a M113 engine, it is the same procedure (per WIS).
