OK, I've posted before about having a "running warm" condition on the 84 Euro. Well, now it's back, and the only way to keep the temps down is to keep the car out of 5th. It doesn't matter if I'm on flat or hilly ground, the temp guage gradually creeps up over 100C in 5th.

It has a new water pump, new radiator, new T-Stat, new radiator cap, and total coolant system flush (lots o' crap came outta that). The hoses are in new condition, and aren't restricting flow. I'm not using any coolant, nor oil. I see no indications of coolant in the exhaust. The injectors passed testing, despite there always being a continual light trail of smoke, with a fuel odor. I want to get the A/C fixed, and be able to do road trips in this car, but cannot untill I get a lid on this annoyance. Any ideas? I'm stumped.
