Can some one either please direct me to some threads that could help me trace down an AC leak in a 94 4.0l awd xlt, or help me find out what i should do? i was thinking recharge the system first, then go from there... but i know aero stars are imfamous for having the gines book of world records for using the most elbo joints in one system... but... dad's feeling jelous of my aero, and he's wanting to get rid of his for another one, but i'd rather fix the problems (it needs new screws to hold the trim on the rear hatch, the AC needs to be fixed, the front diff. needs a new or a re-welded mounting bracket so it stops banging about, i need to find out what is causing the check engine light to come on, the throttle positioning sensor is going bad, the clock springs need to be fixed behind the steering wheel so that the horn/cruise control/air bag will work again, and the transmission, and diff's need to have the fluid's changed out of them0

there may be more, but i highly doubt it. its a GREAT car, and i don't think my dad could really find another one that wouldn't have other problems of some sort...
i have a bit of an atachment to that van too... and it doesn't even have 110,000 miles on it yet, which is why i feel my dad should keep it... we bought it almost brand new from the first owner back in 96, and have used it for lots of things... so... oh yeah i know i've posted things about this van before, but... idk i like it more than mine almost, especialy cuz of the AWD... and yes i know these are personal problems. but yeah is there anythign i can do about the AC?

also, is there a for sale part of the aerostar section?

Thanks!

I always dreaded looking for leaks until recently. I purchased a "Leak detector kit" from O'Reilley's. Consists of an aerosol can of detector, a plastic pair of glasses, a small penlight and an aerosol can of "leak fixer" (which I chunked immediately). The detector has an attached valve for your low pressure side and is good for two times. You have to have a little bit of pressure left in the system. Shoot the detector into the low side for about 3 - 5 seconds, engine on and A/C on high. With the little penlight start looking at all your connections, any leaks will show a bright, flourescent yellow. If this does not show any leaks, then you will have to dismantle the evaporator core housing(s) (two if you have rear air) and check them. Chances are pretty good, though, that it will be O-ring replacement which is pretty simple.

 

Hi Ryan:

Selling is not allowed in the forum, but we do have a classified section for everyone.

About your A/C problem, there is an UV dye you can use, but I usually just look for the oiliest spot in the system and 90% of the time it's the culprit.

Oh really? where might i find this classified section?

Thanks!

 

The leaks are usually under the van going to the rear ac unit if you have one LOL.
The brackets cause the lines to corrode.

Look at the row of buttons right below the big FORD TRUCKS ENTHUSIASTS banner. There is a button for "Classified."
