Friendly A/C reminder and an A/C belt tension question
Hi,
A friendly suggestion, having the original York a/c system filled and working for the first time since owning the car, both fans removed over winter and cleaned up so they run smooth, cold and quiet, I suggest to feel all the connectors for excess heat under operation. The front condenser blower connector next to the battery was almost kettle hot. Sepperated the connectors, soldered and cleaned, now it's cool. The evap in the smugglers box including the relay, mildly warm, cleaned and soldered two or three of them. All connectors now cool. I know there is a fuse that can be added, but this is a quick test that I'd suggest be performed every year. Didn't delete the connectors, just soldered at the crimp, using flux solder. Question Now, York compressor belt to crank, a/c off, belt runs smooth, a/c on and it wobbles about as each compression stroke happens I imagine. How much wobble do we tolerate before tightening? Phil, 81 sc us. Oh yeah, the a/c is like a revelation, not to mention the stereo sounds so good with the windows all up, it's a really nice improvement. * Last edited by ahh911; 07-07-2022 at 08:51 AM.. |

The York compressor is heavy and has a lot of vibration, switch to a Sanden type. Much smoother operation.

From what I've read, the Sanden doesn't come with it's own oil sump, I like the idea of the r12a running low and no harm done to the system until the next refill. No I'll keep the York, will tighten the belt up a smidgen.

If you don't like the Sanden, use the factory type Nippondenso. The HP losses and increased vibration of the York, not to mention less effective operation make the upgrade very worthwhile. You will be surprised.

Thanks,
I'll see how it goes it the hot weather (it's been cool for summer here lately) and if there is any other work to do, the a/c system is now in it's prove in phase as basic functionality works very well. If in time something comes up, I'll look into things, hopefully it continues to blast sub 40F into the cabin (3krpm, fan setting 2) and cycles on and off for next month signaling success and no need to change a good thing. If I suspect compressor issues, I'll check out your suggestions. Phil |
