77 240d ac removal question
I picked up a 77 240d recently as a project and have pretty much had to tear the engine completely apart. It has a factory installed York ac that has seen better days. I should start out with telling everybody that I am a licensened hvac tech.. But this is my first Benz. I would like to completely remove the system including the coils. I have already removed the compressor.
My question is; are there any engine components tied into the ac system that would prevent me from pulling the whole system? |

I can't think of anything but the auxiliary fan which is triggered by an AC system switch. You might not need it without AC.

Sixto- are you referring to the electric fan in front of the condenser coil?

If so I was wanting to keep that fan ..... I'm still used to doing things Baja style having recently movEd from San Diego to Spokane. Really weird not having to use the ac even in August up here

Just leave it all in place so the next person that gets the car if you ever sell it won't have a headache.

I am replacing the radiator in the morning and having another "inoperable" coil in front would restrict airflow to the radiator. Has anyone ever stripped an ac from a 240d
? I don't plan to get rid of this car. It's got low miles and I have 3 sons. It's more of a toy then anything |

Pretty sure you'll have enough airflow even with the coil in place.
No one here has stripped the AC out but if you want it's easy. Only hard part is removing the dash to get to the evaporator but really, why bother. |

Cool thanks for the advice. I think I may pull the condenser out at least.

Yes my friends had some of theirs removed actually. The big plus to deleting the A/C is removing the bracket the compressor mounts on. With it gone it gives you very easy access to the starter, water pump, and alternator. With it on there all of those things become a pain in the ass to access. I wouldn't go to the trouble of removing anything other than the compressor, bracket, and condenser though.

Seriously that stupid bracket took me an hour to get out. Thankfully that's done now and I was able to work on the alternator and also some of the wiring in that area

I assume it's a manual system - those are really nice; I'd keep it in place - at least all the parts in the cabin.

The Haynes manual shows two triggers for the auxiliary fan - a 100*C engine coolant switch and a 62*C refrigerant switch. The switches are independent so disconnecting the refrigerant switch won't disable the coolant switch... assuming you don't rip out the harness with the AC hardware.

I do plan to keep the components and rebuild the unit at some point. I have been doing hvac for over 10 years and have never had the chance to tinker with such an old one. But I prolly won't put it back in this car. It has a few too many dings in my opinion to be completely restored so I am just going to do it up rally style ( even though it's an automatic) the streets are pretty rough in some places here.
