AC load

[e34musician]

I noticed a dramatic AC load on the engine when it's on. I feel it when merging into the freeway. Do you V8 guys feel the same thing? I was wondering if it's just mine. Maybe it's "chip" time. I am still on a stock DME.

Another quesion, is there any need to service AC compressor like oil change, pulley change? Thanks!

When I set the climate control to ~69F, I almost don't feel the load at all. It may depend on the outside temp as well. Anyway, overall, not as bad as I thought/feel earlier.

I guess my only question is how we service the compressor? And do we need to? My A/C is still blowing very cold.

If it works... don't touch it. No service required unless you lost refrigerant.
