It Was A Dark And Stormy Night........
No, really, it was. We've received over 4-1/2" of rain in the last couple of weeks, and since I won't take Ms Swan out in the rain, I thought it would be a good time to change out the slooowly failing alternator with the new, higher capacity unit I bought a while back. I've swapped more than couple of alternators in the past, and it's generally a pretty straight forward job, when you can see all the bolts. The car had a pinhole leak in the power steering high-pressure hose, which sprayed out a fine mist at certain times. The mist coated that side of the engine, and the underbody, with a mix of road grime and hydraulic oil. The resultant gunk was about 1/4" thick in spots, meaning I couldn't see the bolts to get a wrench on them. This is after a quick douse and brush with a bit of mineral spirits. The slider on the threaded rod was completely jammed with gunk, and I could't move the alternator enough to loosen the belt.
Prior to cleaning this bracket and adjustment bolt you couldn't see them. To get to this point, however, I had to remove the pulley on the power steering pump.
And it's on there really tight.
Takes a big wrench, lots of grunt, a dash of PB Blaster, and a means to hold the damn thing while you break the nut loose.
The pulley had to come off to reach a bolt holding the alternator bracket (the jammed-with-crud bracket) to the block. This required pulling the cooling fan and fan shroud. To pull the fan shroud requires you to remove the top radiator hose, which means draining a bunch of coolant. If I'm going to do that, I might as well replace both radiator hoses. That required pulling the radiator, as the degraded bottom hose was stuck on there so tight that I had to cut it to pull the radiator. The hose clamp is also installed perilously close to the end of the outlet, and was barely clamping the hose on. Looks like it was in a different place during it's life, too.
Since the coolant had been drained, I decided to look into "The Case Of The Missing Thermostat", or so I thought because the engine ran too cool, rarely reaching the normal zone on the gauge. The water out of the engine through the top hose also showed immediate warming from a cold-start, a sure sign of a missing thermostat.
Surprise, Surprise, Surprise!
It had one in it, but it was stuck wide-open.
It was also installed wrong, as the "Jiggle Valve" should be at the top to allow air to bleed out as you fill the engine with coolant.
So I'm cleaning a ton of parts, including those it's very hard to see or reach with these various bits on the car.
And as long as I'm this far into it, I'm going to go ahead and change the cam drive belt, tensioner, and spring.
And It All Began On A Rainy Day......
