After only three tanks of atf, I decided to NOT put any atf in this last tank. I filled her up last night on the way home and parked her for the night. This morning I had to go downtown to talk to those friendly folks at the IRS, so I took the freeway(yay!). Great googily moogily, after a 10 minute run at highway speeds, I was back on surface roads and old girl sounded like crap, well not crap but that tick I thought was a header exhaust leak was back, and she was running warm for her...it was only 92 degrees and her fan came on(her fan doesn't even come on when it's 112 at stop lights). I was only in the IRS building 5 mins and when I started her for the ride to work the fan came on again like she was still hot...did I lose the waterpump on the freeway? Well, I shut her down and put the atf in the tank. Half way to work on city streets she cooled down and the tick was already gone. Ride home? Normal, 107 and the fan never came on once. It looks like it's atf in every tank from now on.
I think the fan thing was just an anomoly, but the benefits of atf are undeniable.
