Ok, first my hottest temps I can remember are around 195, going over 4th of July Pass on the way to Montana, maybe I hit 199-200, not over that.
Second - I keep the RPM's at 1500 or so and manually put into 4 going up steep hills. No toad behind the coach up to now, but on Thursday, I am setting up the jeep.
I am far more concerned about my transmission temps, and start to really worry if they get over 203 or so, so I watch them like a hawk, maybe more so than needed.
I always have the ventilation on, not necessarily the A/C. I check the hydraulic reservoir level each trip, have not noticed any leakage.
Cummings finally fixed my front plate oil leak, so I'm happy about that. After Dale's comments about his radiator spacing, I checked mine, 07 Non Smog Engine ISL400, and they look correct, at least to my untrained eye they are.
I cannot tell you with any accuracy what I have in the Hydraulic Reservoir, and believe there is a tag, but don't remember what is written on it, if it's there and I remember I will update this post with that info, as to what it contains.
I do seem to have to push on the brake pedal to get the old girl to stop, but I attributed that to lots of mass, slowing it down, Newton’s law or some such thing. Still wish it had air brakes on it. Too many hydraulic systems on the thing, with WRV’s crappy quality control, the thing could have a bad day, and I too untrained to figure out what it is.
