so I'm on the cusp of parking the Dakota for the winter and figured the easiest vehicle to get to DD status (not that I have a job or anything that I go to daily) was the ol' 97 caravan since really the only issue was the stalling thing and that should be easy enough to tackle. today I drop in a battery (been parked for a few months), turn the key and she starts right up. success! or so I thought. a few seconds after ignition, smoke starts billowing out of the engine bay. some more investigation indicates that it's coming from the AC compressor pulley. after letting everything cool down, I try again and get the same result. a few secs after it fires up, the smoke starts.

 

AC clutch issue? does the same thing if the AC is turned on.

Compressor and clutch seizure is fairly common for the minvans, but I wasnt sure that the problem went back that far.......

 

More reaseach finds it is in the next gen RS model minivans ( your is an NS but they use the same engines therefore probably same compressors? ) The ones Ive seen have had the compressor and clutch lock up, causing a breakaway plate in the compressor clutch to break and melt away causing a huge amount of smoke till enough has burned away to give clearance for normal pulley operation without belt breakage. We replace the comporessor, the receiver dryer, and suction and discharge line from compressor when we see this come in.

Is the compressor locked up? Did you try spinning it by hand w/o the belt?

brilliant me, I drove over there (it's stored at my grandma's house) with the 13mm wrench, and only the 13mm wrench, only to find the tensioner pulley needs a 15. :fool: I was soooo sure it was a 13. :doh: Sun or Mon I'll be going back with more tools.

 

I have no problems dumping the AC on it if it comes down to that. doesn't work anyway. :( plus winter's coming. :D plenty of that gen van in the pull-a-parts.

 

The ones Ive seen have had the compressor and clutch lock up, causing a breakaway plate in the compressor clutch to break and melt away causing a huge amount of smoke till enough has burned away to give clearance for normal pulley operation without belt breakage.

 

so you're saying this is a self-curing problem? :brows:
