2008 Chevrolet Colorado A/C Accumulator Parts and Q&A

• Q: How to replace the A/C Accumulator in an A/C system on 2008 Chevrolet Colorado?

  A: The A/C Accumulator replacement process begins by evacuating the refrigerant through the usage of the halogen leak detector (J 39400-A). It is necessary to remove the grille but avoid pulling any hoses or lines before the system discharges its r134a completely because of safety reasons for human injuries. Duplicate the process by first removing the condenser hose bolt then the condenser hose from the A/C Accumulator before proceeding with the evaporator tube bolt then the evaporator tube. Cap both the condenser hose and the evaporator tube assemblage to stop moisture from entering and oil leakage. First free the bolts securing the A/C Accumulator bracket followed by the removal of the accumulator assembly and final removal of the accumulator by loosening the clamp bolt. To replace the A/C Accumulator, proper pag oil amount must be added to the system. Install the A/C Accumulator bottle to the clamp but do not tighten it before placing new o-rings. The r-134a a/c system requires pag as its internal circulatory fluid but fitting threads and o-rings need 525 viscosity mineral oil to avoid compressor breakdown. Secure the A/C Accumulator in position through bolts before tightening the accumulator clamp bolt to 5 n.m (44 lb in). Seal washers for the condenser hose and condenser cap should be replaced after plugging and removing the condenser hose to condenser cap assembly. Connect the A/C Accumulator evaporator tube with its bolt installation while tightening it to 20 n.m (15 lb.ft.). Fasten the condenser hose while beginning hand torking on the bolt then tighten it to 20 n.m (15 lb ft). The a/c system needs evacuation and recharging before the halogen leak detector (J 39400-A) checks component fittings that lead to grille reinstallation.
