Loren, the 2nd one you describe is how I'd want it to behave (and how mine behaves now that I've corrected several things, including new radiator, new temperature switch on the radiator, new temperature sender on the thermostat housing). Mine is '01 camper 2.1L engine, 4 speed manual transmission, and it behaved in part like the 2nd one you describe (except mine got too hot, needle rising to near the top of the "normal" range when climbing or even when in hot summer temperatures (over 100 F).

Wow, what a big engine you have (21.L). Speedy?
