2014 Mercedes E350 thermostat replacement.

Last video when I was cleaning the oil trap. I notice the dry and wet coolant around the thermostat assembly, so is what we doing today, I purchase a thermostat kit online, contain the housing ( thermostat inside), the coolant, and several gaskets to complete the job successfully .
at the end of the job the vehicle was running hot 98C' after letting the car seat and restart and drive the gauge came back to normal. 90C' .

Take a couple minutes and pull that belt. Coolant will soak a belt and make them squeel indefinetly. Trying to clean them after the fact usually just makes things worse.

AND I just noticed you didn't dilute the coolant before filling the bottle! The coolant should be diluted 50/50 with water BEFORE filling the system, I know it wont hold 2 Gallons so you are messed up!!

True dat!

How many gallons will I need if I replace both thermostat and water pump?
