CL65 normal operating engine/water temperature
Guys,
Does anybody know what is the normal (official standard) engine/water temperature range for '05 CL65? I cannot find this information anywhere.
Mine keeps showing somewhere betw. 80C and 90C, I just feel this may be a bit too high...?

Mine seems to always be around 80, but once I was stuck in traffic for over an hour and it reached over 90, I was concerned but my garage assured me it would not overheat because of the hot and cold weather testing done by

I am having this issue as well. I have never seen a vehicle without a cooling system issue fluctuate water temps this much. (Assuming there is no issue.) At ambient temps around 30f-40f my water temp stays right around 80c. Today it was 55f ambient and water temp was around 90c-95c. Needless to say I am a little concerned.
In searching the forum it looks like I should upgrade my IC pump and heat exchanger. I won't be able to do that right away so I am inquiring as to weather I have cause for concern or not.
That being said, recommendations for heat exchanger and IC pump would be helpful. What have your experiences been?
