Went out to my truck this morning like I always do when its cold and start it. It was 45 degrees outside. Fired the truck up and put the idle up feature on to about 1200 RPM. A/C light was on BUT was actually set up to heat the cabin of the truck with the thermostat.


When I walked outside 15 mins later I hear something coming from the front of the truck and look under and the A/C Compressor is spraying a freon / oil looking liquid on the ground out of a vent hole on the bottom back side of compressor. Then it stops. I get in the truck and put the thermostat to COLD and the truck gets cold like it normally would.

THE AMOUNT OF LIQUID / FREON WAS PROBABLY A 12" PIE PLATE AND LOOKS LIKE IT WAS BLOWING JUST A FEW SECONDS...


Anyone have any suggestions or has experienced this before.

This is the 2nd A/C System put in this truck but I have about 30K since the last compressor and fan clutch was replaced.

Thanks for any info....

John

High-pressure relief valve on the Halle compressor... pretty common for them to keep venting more frequently once the seal is lifted.

Everything seems to be alright now! call me with questions (412)997-5722

Wow, that's an expensive compressor job... a Halle is ~$300 from the dealer & labor should be less than 2 hrs.

Since it's an automatic I would check between the condenser and intercooler for trash to buildup that could restrict airflow over the condenser causing a heat buildup if it don't get enough air to cool the condenser it can get hot and blow off excess pressure from the heat
