Re: bypassing the ac compressor????

That's an easy one as I did something similar after removing my A/C compressor. You just need to buy an alternator belt for a 2001 Civic DX. They came stock without A/C and that belt will fit.

Is it possible to bypass an A/C compressor on a 2001 Honda Civic EX? If so, how?

Re: bypassing the ac compressor????

Thanks for this info. It worked great for me for a 2002 Civic EX. Found belt 5060340 at an Advance near me, but not many had this belt. Seized compressor does not interfere with new belt going from crank to alternator. I was missing the adjusting bolt on the alternator so had a hard time trying to tighten the belt. Part not available near me, so went to home depot and got a Hex bolt M8-1.25 x 65mm, class 8-coarse. It worked perfect and was easy to tighten belt. One question, should I remove ac fuse? Just wondering what effect if ac button gets turned on since system still seems to be charged. Thanks

Checked a wiring diagram. I would not pull the fuse, because that may also disable one of the radiator fans.


I'd open the engine compartment fuse box and remove the relay for the AC compressor clutch instead.

Relay labeled D in this diagram:

Re: bypassing the ac compressor????

Will a serpentine belt for a 2011 Honda Civic 1.8L without AC fit if I want to bypass the AC compressor or, will I need a different length?

Assuming you have a 2011, a belt for a car without AC would get the job done quick and simple

I prefer to fix the real problems though.

Re: bypassing the ac compressor????

Just be sure to tighten all 4 alternator mounting bolts/ wingnuts correctly.

Civic DX doesn't come with AC, at least here in America. But the belt you need to run the alternator without an AC compressor is shorter than the belt for a car with AC since it goes right from the crank pulley to the alternator pulley and doesn't have to reach the AC compressor. Just go to a parts store and tell them you need an alternator belt for your 01 Civic with no AC, they should have one.

Re: bypassing the ac compressor????

I have a '03 Honda Civic Sport from Canada, The a.c. unit is about to seize or melt the serpentine belt. Will the alternator belt for a '01 Civic work to bypass it? Any help would be greatly appreciated.

Thank you for the info and yes I read it all. Just making sure before I buy the part. I'm new to working on cars and since its a Canadian car I wasn't sure if it needed different parts.

Re: bypassing the ac compressor????

Hey for the record, I just did this on my 2003 Honda Civic Hatchback 5-door (EU model). My compressor had been making noise for a bit, so I stopped driving but periodically had been running the car in idle in the parking lot. Finally one day the compressor seized entirely and the engine would not start.

I wasn't able to find the DX model, but through a lot of research online on what other people did, I figured out that the correct belt length to bypass the compressor was ~865mm so i bought a 6PK862 belt and just attached it last night and it's working very well. I do not have power steering, so it was extremely easy to install as I just removed the old belt and installed my new one without looping around the compressor (just alternator and crankshaft).

Thanks to everyone on this thread for the advice!
