In searching this and other jeep forums, I get the feeling that the stock XJ cooling system is inadequate for the most part.
My girlfriend's XJ, on it's first long trip under her ownership, started exhibiting some overheating behavior, I just want to know if this is the typical behavior for an XJ before tearing into it:
truck will cruise at 55-65mph all day long with a/c on around 220 degrees. about 215 with a/c off.
Cruising at 75 with the a/c on, causes truck to creep well above comfortable, prompting us to slow down and turn on the heater.
(speed limit is 75 on I-10 in AZ)
Engine sits below 2500 RPM at 75mph (i'm used to 3100 in my truck!) and transmission doesn't feel like it's slipping, doesn't shift erratically. Flat ground.
1987 XJ wagoneer 4.0L automatic / NP242 (in 2wd) and 3.55 gears on 205/75-15 street tires.
Is this how the cooling issues usually look?
