Ali:

I'm not familiar with your model of MB; however, there are some basic principles that apply across the board.

- Many T-Stats have an air bleed valve on them that must be positioned at the highest level.

- You may have introduced air into the system when the coolant was changed.

- What mixture of coolant-to-water is now being used vs. before? Excessive coolant can cause increased temps. as coolant does not disperse heat very well.

Regards.
