I have a 74 400 and it has, what I believe is an A/C unit on top of the water pump. I have no use for it and want to remove all that extra useless iron. But, I have never removed an A/C unit, are there any pitfalls in pulling it off? Anything I need to be wary of?  (sorry the pic is sideways) |

All you gotta worry about are the hoses and any possible fluids and you'll also need smaller belts for the alternator to make up for the lost pulley. If the a/c hasn't worked since the 90's, like I suspect mine did, it should be dry and nothing to worry about. Press the valve open on the hose elbow, at the back of the compressor to let out built up pressure. If it goes more than a few seconds before slowing or if fluid comes out, cap it and take it to a shop to get evacuated. I'd take the hoses off back to the evaporator on the firewall and plug the tubes, don't need those flopping around. There were big nuts (1 1/16" I think) attaching the hose and that long pipe strapped to the wheel well to the evaporator tubes. You can take the expansion valve off too. On mine, there were 3 or 4 bolts holding the compressor to the block. Keep track of which brackets go where, some of them are multipurpose. On mine, I think the bracket near the steering pump is where the ground wire and pedal return spring hooks. Remove the hoses from the condenser and plug or remove that. The tall, black, cylinder that's strapped to the body, (I think I can see it in the very top left) is the filter/drier. It's hooked to the other side of the condenser, you can take that out too. If you do any work on your own car and are familiar enough with what's what, it shouldn't be too much work. You might need some liquid wrench, cause those nuts are gonna be on there tight. PS. I don't know if it's just me, but I save everything that I take off. Those A/C parts might be salvageable and they're really hard to find. So keep them around, maybe give them to someone who's fixing up their Mopar's A/C. Thankfully all my hoses and pipes were still good, because I couldn't find replacements anywhere! |
