For about a week, brush/grass/wildland fires were getting pretty prominant in my area, so my paid FD's brush truck was getting called out to assist our neighboring dept.

Two fires occured during my shift, but it wasn't until the second one that I noticed the temps for the coolant and tranny. With as late as it is right now, I've forgotten the tranny's temp, but I do remember the coolant temp was getting up to about 210*. This was on the return trip to the station.

The rig was driven near 55 mph for most of the call to the scene and at low speeds for about 15-20 mins on scene, with some brief idling. When I noticed that temp I was driving the rig at 55 mph on the highway and the temperature was around mid 50s. Coolant is nice n' green, but I think getting that high was not normal.

So, can anybody let me know what the normal operating temp for coolant and transmission is for highway use? BTW, I did some searching and couldn't find nothing directly related to what I'm looking for, but if a thread does exist, please point me in the right direction.
