Re: 1998 honda civic a/c compressor replacement...

Pugal, you may have another option? I think I had a very similar problem
caused my me. My severe hesitation on hot days was caused by my almost
new AC compressor having too much refigerant. I had added a half can of
the factory 134-A refigerant (not freon)in the spring without monitoring
the guages last April. As the weather got hotter, I was getting a belt
squeal on hot days that was dragging down the engine rpm's. I thought I
had a fuel / main relay problem. When I finally put the guages on the AC
last week the high side was reading well over 300 psi at medium rpm. The
higher the rpm the higher the pressure and the more of a load it puts on
your engine. Max pressure on your Civic is 300. Your high side should be
between 240 and 300 psi. Low side should be between 22 and 36 psi. Any
chance someone overloaded your AC with refrigerant?
I would go back to the dealer and have them physically show you the
pressure readings. If they are high, bleed a little off slowly until you
get a 280 psi reading at medium rpms. I hope this helps? Good luck.
