EVAPORATOR, CLEANING WITH Suction Feed Spray Gun :VAG1538 AND SPRAY LANCE: Notes

WARNING: This page is about a different variant/trim than selected.

Special tools and workshop equipment required 

WARNING:

A/C unit may be contaminated by other substances

  • Only use a suction feed spray gun and a spray lance that were not already used with other fluids.
NOTE:

The vacuum cleaner is only necessary if there is dirt in the plenum chamber or in the A/C intake shroud, or if dirt has gotten into the evaporator housing through the dust and pollen filter.

The Suction Nozzle With Brush :VAS6288  is only necessary if dirt has gotten into the evaporator housing through the dust and pollen filter.

It is recommended to have several short and long spray lances, since they are used either in their straight form, or must be bent to different degrees for various vehicles (or they are already bent). Repeatedly changing the form of the spray lance will damage it and is therefore not advisable.

Recommended bend radius of the Suction Feed Spray Gun - Probe for Evaporator (Straight) :VAG1538/5  -A- for this vehicle.

The guide washer -B- is attached opposite of the spray lance holes -C-. This also allows the spray direction to be recognized when the spray lance is inserted.
