    High Temps?

    Yesterday on a 3 hour trip (90 degrees) I noticed my temp (on the gauge) was a little higher than normal. On the Eldo it usually sits right in the middle of the gauge reguardless of all other exterior conditions. I noticed while drving a back road (hills etc) with my air on, the temp actually moved up an entire notch on the gauge. Is this normal? Its the first time I have seen this happen and I am planning on going on a 11 hour trip next week.

    It doesn't sound unusual to me... For lower speed driving on hills and such on a 90 degree day...??? One would expect the coolant temp to increase slightly. From what you said, I wouldn't worry about it at all. Coolant temps change all the time depending on engine speed, load, ambient temp, AC demand, etc... Anything from 200 to 240 could be considered "normal" under the right conditions. For the coolant temp to increase slightly in a higher load, lower speed situation (hills and less ram air due to slower speeds..??) with concurrent high AC load on a 90 degree day is nothing to worry about. Put tape over the temp gauge and drive the car. There are multiple warnings about the cooling system and impending problems. There is the low coolant warning, several levels of temp warning, the system will automatically shut off the AC if it gets WAY too hot and then the loss of coolant protection mode will kick in if the system boils dry and you need to get to a safe place. You have a lot of redundant systems to warn you that should give you peace of mind.
