OVERHEATING
So... I spent all day today, and the better part of yesterday fighting the old fight. I thought I'd fixed the overheating issue, all those years ago. I have NEVER had a fox put up an overheating fight like this, and I'm starting to think that one of the coolant ports has a blockage, if one of the head gaskets isn't turned around.
During a 96 degree day, I was able to cruise about 15 miles, but not with the A/C on. The temp gauge stayed near the top of the gauge, pointed at the "N", which seemed to be in the 195-210 range using an infrared sensor on the T-stat housing. Later the T-stat housing went as high as 230* before I heard what I thought was detonation and shut it down. I swapped the stock water pump pulley back on in place of the U/D pulley that was on it. Then I drained the coolant, pulled out the radiator. The Ron Davis Radiator's fins were clean as a whistle, both inside and out as far as I could tell, and the fluid was beautiful, though probably a 50/50 mix. Pulled the T-stat out -- wanted to ensure there were no air bubble or T-stat shenanigans. Refilled with water only, though there was still coolant in the block. I let it idle with the A/C on and the temps pushed over 195*, this evening while it was 84* outside. It was still climbing. When I shut the A/C off, it stabilized and dropped to the 193 range. Then I spun the motor a little faster @ 1,500 RPMs and the temps dropped quite a bit. That tells me pretty clearly that the U/D crank pulley has got to go, and the stocker will go back on tomorrow.
This one is a bit of a stumper. I think I'll bring timing back down to stock to protect the motor when it's hot if the stock crank pulley doesn't get rid of the issue.
ELECTRICAL
One thing that did change was the head unit. It was not worth whatever Mark paid to do it, though. The electrical is a cluster F, now. Lights aren't working right. I've got an airbag light. The blinkers are intermittent. Turning on the lights causes the gauges to completely spaz. No instrument cluster backlight. The line lock no longer functions. I guess it all stemmed from whomever did the stereo system. Some genius ran the amp's wire through the driver's fender, through the rubber boot in the door to get into the cab, and then down the floor board. Hopefully, I can get into the dash wiring tomorrow and find a simple fix, but I suspect I'm going to find a hack job.
