SERVICE - Custom A6 Compressor/Clutch Rebuild

$390 plus s/h. Requires a rebuildable core.
SKU: 17-A6-c
Make: PONTIAC
Call for availability
Custom rebuild of your original A6 compressor and clutch core. Rebuild consists of initial test to determine if the core is serviceable *, followed by stripping exterior surfaces to bare metal and dismantling. Compressor gut pack, reed valves, oil pump gears and valve plates are cleaned inspected and reinstalled along with a new shaft seal and o-rings, a full 11 oz. oil charge is added and the compressor is pressure tested for leaks with Nitrogen at 250 psi. Both clutch pulley and hub surfaces are resurfaced and installed on the compressor with a new bearing and the unit is performance tested at 1800 rpm's and painted. *NOTE 1 - Initial serviceable diagnosis of the compressor is not a guarantee that a rebuild can be completed. In most cases we can still use your original housing and replace the gut-pack at an additional cost. NOTE 2 - In many cases we can save the original decal and/or duplicate the original "OK FINAL TEST" stamp. New decals may be available at an additional cost.

CONVERTING GENERAL MOTORS CARS

TO 134a

Until 1995, most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. since then, the industry standard has been R134a, which is an efficient replacement.  Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool.

 

1955-61 Models with Hot Gas Valve (aka By Pass or Hot Gas By Pass Valve)

The Hot Gas Valve is most often found mounted to the compressor, though some cars have it mounted back near the evaporator. The front half of it looks like a bullet. (Click here for a typical photo)

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Rebuild hot gas valve.
  • Install 134a charge port adapters.
  • Charge with 134a between 70-80% of the original R12 charge amount. Note: Hot gas valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

 

1962-66 Models with Suction Throttling Valve (aka STV)

The suction throttling valve is installed on the evaporator, near the firewall.(Click here for a typical photo)

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Rebuild suction throttling valve.
  • Install 134a charge port adapters.
  • Charge with 134a between 70-80% of the original R12 charge amount. Note: Suction throttling valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

 

1966-73 Models with POA Valve

The POA Valve is installed on the evaporator, near the firewall. (Click here for a typical photo)

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Install 134a charge port adapters.
  • Have POA valve recalibrated/rebuilt for 134a, or replaced with a POA Delete Kit
  • Charge with 134a between 70-80% of the original R12 charge amount.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

 

1973-76 Models with VIR

The VIR is installed on the evaporator, near the firewall. (Click here for a typical photo)

Minimum Requirements

  • Change desiccant in VIR.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Install 134a charge port adapters.
  • Charge with 134a between 70-80% of the original R12 charge amount.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch
  • Install our VIR Eliminator (strongly recommended when converting to 134a), purchase a rebuilt VIR or let us rebuild yours.

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

 

1977-Newer Models with Accumulator

Minimum Requirements

  • Change or restore the accumulator.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
