I posted this on a Ford Mustang forum and haven't gotten answer. Or even any looks. I thought I'd try my luck here. ------------- After I wrote this, I realized how long it is. I shall summarize now. '89 LX 5.0 convertible. Runs great, save for few minor problems. 1. No AC. Request parts list for full AC replacement. 2. Has smog pump. Want it gone. Any special considerations? 3. Rear right suspension thunking, as if loose. Can convertible boot be opened from inside to access where tower bolts to car? 4. When tranny is cold, misses or grinds into reverse. Causes? Fixes? 5. Rad fan removed by previous owner. Current fan too small and held in with coat hangar wire, as is rad overflow tank. where does tank go, what size fan to replace? As the title says, I bought an '89 LX 5.0 convertible. So far all I've had to do is put new tires on her, alignment, and replaced the front left brake line. Otherwise the car runs like a champ. But there are a few things I'm not too sure about, and so I come to you. Also, most of what I've got to say came from a friend who has alot more Ford experience than I do, so don't shoot the messenger. I'd also like to state I'm mechanically inclined, but not a mechanic, so with some ok instruction, I can do just about anything. 1. My car has no AC. Yeah, it's a conv, but Arizona is damn hot. The guy who had the car before the guy I bought it from removed all the major components, but left a bunch of tubes and piping. I dunno. I'm just going to buy all the parts I need and install everything on a weekend. So what I'm looking for is a parts list for an AC replacement. Everything I need to get the cold blowing. 2. My car was at one time a California legal smog machine, as is evident by a smog pump. I want it gone, much on the same principle of removing the AC. Is this a good idea? If so, what do I need to do besides unbolt and get a shorter belt? 3. There's this annoying thunking coming fron the right rear suspension. I'm lead to believe it's a loose strut tower. It sounds like something hitting sheetmetal in response to suspension movement. If I detach the convertible boot from the inside, can I access the top of that tower to wrench it down? Or do I need to go in through the trunk? 4. When the transmission is cold, it'll grind a bit or totally miss the gear when I shift into reverse. I put the stick there and I don't get backwards. Doesn't happen when I pull in after I'd driven it awhile. Anything I can fix without dropping the tranny? 5. For some reason a prior owner removed the clutch fan (correct?) and replaced it with a much smaller electric fan that's turned on and off with a switch in the cab. I leave it on, (Arizona's hot, remember?). Also, the fan is held in there with coat hangar wire, along with the radiator overflow reservoir. Where does the reservoir usually go and what size fan should I have for my car? All in all, that's what's wrong with my car. I greatly appreciate everyone who reads this and has anything helpful to say. Take care.
